Social media users may need to think twice before hitting that “Post” button.

A new large-language model (LLM) developed by Georgia Tech researchers can help them filter content that could risk their privacy and offer alternative phrasing that keeps the context of their posts intact.

According to a new paper that will be presented at the 2024 Association for Computing Linguistics(ACL) conference, social media users should tread carefully about the information they self-disclose in their posts.

Many people use social media to express their feelings about their experiences without realizing the risks to their privacy. For example, a person revealing their gender identity or sexual orientation may be subject to doxing and harassment from outside parties. 

Others want to express their opinions without their employers or families knowing.

Ph.D. student Yao Dou and associate professors Alan Ritter and Wei Xu originally set out to study user awareness of self-disclosure privacy risks on Reddit. Working with anonymous users, they created an LLM to detect at-risk content.

While the study boosted user awareness of the personal information they revealed, many called for an intervention. They asked the researchers for assistance to rewrite their posts so they didn’t have to be concerned about privacy.

The researchers revamped the model to suggest alternative phrases that reduce the risk of privacy invasion.

One user disclosed, “I’m 16F I think I want to be a bi M.” The new tool offered alternative phrases such as:

• “I am exploring my sexual identity.”
• “I have a desire to explore new options.”
• “I am attracted to the idea of exploring different gender identities.”

Dou said the challenge is making sure the model provides suggestions that don’t change or distort the desired context of the post.

“That’s why instead of providing one suggestion, we provide three suggestions that are different from each other, and we allow the user to choose which one they want,” Dou said. “In some cases, the discourse information is important to the post, and in that case, they can choose what to abstract.”

WEIGHING THE RISKS

The researchers sampled 10,000 Reddit posts from a pool of 4 million that met their search criteria. They annotated those posts and created 19 categories of self-disclosures, including age, sexual orientation, gender, race or nationality, and location.

From there, they worked with Reddit users to test the effectiveness and accuracy of their model, with 82% giving positive feedback.

However, a contingent thought the model was “oversensitive,” highlighting content they did not believe posed a risk. 

Ultimately, the researchers say users must decide what they will post. 

“It’s a personal decision,” Ritter said. “People need to look at this and think about what they’re writing and decide between this tradeoff of what benefits they are getting from sharing information versus what privacy risks are associated with that.”

Xu acknowledged that future work on the project should include a metric that gives users a better idea of what types of content are more at risk than others.

“It’s kind of the way passwords work,” she said. “Years ago, they never told you your password strength, and now there’s a bar telling you how good your password is. Then you realize you need to add a special character and capitalize some letters, and that’s become a standard. This is telling the public how they can protect themselves. The risk isn’t zero, but it helps them think about it.”

WHAT ARE THE CONSEQUENCES?

While doxing and harassment are the most likely consequences of posting sensitive personal information, especially for those who belong to minority groups, the researchers say users have other privacy concerns.

Users should know that when they draft posts on a site, their input can be extracted by the site’s application programming interface (API). If that site has a data breach, a user’s personal information could fall into unwanted hands.

“I think we should have a path toward having everything work locally on the user’s computer, so it doesn’t rely on any external APIs to send this data off their local machine,” Ritter said.

Ritter added that users could also be targets of popular scams like phishing without ever knowing it. 

“People trying targeted phishing attacks can learn personal information about people online that might help them craft more customized attacks that could make users vulnerable,” he said.

The safest way to avoid a breach of privacy is to stay off social media. But Xu said that’s impractical as there are resources and support these sites can provide that users may not get from anywhere else.

“We want people who may be afraid of social media to use it and feel safe when they post,” she said. “Maybe the best way to get an answer to a question is to ask online, but some people don’t feel comfortable doing that, so a tool like this can make them more comfortable sharing without much risk.”

A Georgia Tech researcher will continue to mitigate harmful post-deployment effects created by artificial intelligence (AI) as he joins the 2024-2025 cohort of fellows selected by the Berkman-Klein Center (BKC) for Internet and Society at Harvard University.

Upol Ehsan is the first Georgia Tech graduate selected by BKC. As a fellow, he will contribute to its mission of exploring and understanding cyberspace, focusing on AI, social media, and university discourse.

Entering its 25th year, the BKC Harvard fellowship program addresses pressing issues and produces impactful research that influences academia and public policy. It offers a global perspective, a vibrant intellectual community, and significant funding and resources that attract top scholars and leaders.

The program is highly competitive and sought after by early career candidates and veteran academic and industry professionals. Cohorts hail from numerous backgrounds, including law, computer science, sociology, political science, neuroscience, philosophy, and media studies. 

“Having the opportunity to join such a talented group of people and working with them is a treat,” Ehsan said. “I’m looking forward to adding to the prismatic network of BKC Harvard and learning from the cohesively diverse community.”

While at Georgia Tech, Ehsan expanded the field of explainable AI (XAI) and pioneered a subcategory he labeled human-centered explainable AI (HCXAI). Several of his papers introduced novel and foundational concepts into that subcategory of XAI.

Ehsan works with Professor Mark Riedl in the School of Interactive Computing and the Human-centered AI and Entertainment Intelligence Lab.

Ehsan says he will continue to work on research he introduced in his 2022 paper The Algorithmic Imprint, which shows how the potential harm from algorithms can linger even after an algorithm is no longer used. His research has informed the United Nations’ algorithmic reparations policies and has been incorporated into the National Institute of Standards and Technology AI Risk Management Framework.

“It’s a massive honor to receive this recognition of my work,” Ehsan said. “The Algorithmic Imprint remains a globally applicable Responsible AI concept developed entirely from the Global South. This recognition is dedicated to the participants who made this work possible. I want to take their stories even further."

While at BKC Harvard, Ehsan will develop a taxonomy of potentially harmful AI effects after a model is no longer used. He will also design a process to anticipate these effects and create interventions. He said his work addresses an “accountability blindspot” in responsible AI, which tends to focus on potential harmful effects created during AI deployment.

From airplanes to soda cans, aluminum is a crucial — not to mention, an incredibly sustainable — material in manufacturing. Since 2019, Georgia Tech has partnered with Novelis, a global leader in aluminum rolling and recycling, through the Novelis Innovation Hub to advance research and business opportunities in aluminum manufacturing.

Novelis and the Georgia Institute of Technology recently co-hosted the 19th International Conference on Aluminum Alloys (ICAA19). Held on Georgia Tech's campus, this event brought together the brightest minds in aluminum technology for four days of intensive learning and networking.

Since its inception in 1986, ICAA has been the premier global forum for aluminum manufacturing innovations. This year, the conference attracted over 300 participants from 19 countries, including representatives from academia, research organizations, and industry leaders.

“The diverse mix of attendees created a rich tapestry of knowledge and experience, fostering a robust exchange of ideas,” said Naresh Thadhani, conference co-chair and professor in the School of Materials Science and Engineering

ICAA19 featured 12 symposia topics and over 250 technical presentations, delving into critical themes such as sustainability, future mobility, and next-generation manufacturing. Keynote addresses from leaders at the Aluminum Association, Airbus, and Coca-Cola set the stage for insightful discussions. Novelis Chief Technology Officer Philippe Meyer and Georgia Tech Executive Vice President for Research Chaouki Abdallah headlined the event, underscoring the importance of Novelis’ partnership with Georgia Tech.

Marking the fifth anniversary of the Novelis Innovation Hub at Georgia Tech, Hub Executive Director Shreyes Melkote says that “ICAA19 represents a prime example of the close collaboration between Novelis and the Institute, enabled by the Novelis Innovation Hub.” Melkote, a professor in the George W. Woodruff School of Mechanical Engineering, also serves as the associate director of the Georgia Tech Manufacturing Institute.

“This unique center for research, development, and technology has been instrumental in advancing aluminum innovations, exemplifying the power of partnerships in driving industry progress,” says Meyer. “As we reflect on the success of ICAA19, we remain committed to strengthening our existing partnerships and forging new alliances to accelerate innovation. The collaborative spirit showcased at the conference is a testament to our dedication to leading the aluminum industry into a more sustainable future.”

When it comes to manufacturing innovation, the “valley of death” — the gap between the lab and the industry floor where even the best discoveries often get lost — looms large.

“An individual faculty’s lab focuses on showing the innovation or the new science that they discovered,” said Aaron Stebner, professor and Eugene C. Gwaltney Jr. Chair in Manufacturing in the George W. Woodruff School of Mechanical Engineering. “At that point, the business case hasn't been made for the technology yet — there's no testing on an industrial system to know if it breaks or if it scales up. A lot of innovation and scientific discovery dies there.”

The Georgia Tech Manufacturing Institute (GTMI) launched the Advanced Manufacturing Pilot Facility (AMPF) in 2017 to help bridge that gap. 

Now, GTMI is breaking ground on an extensive expansion to bring new capabilities in automation, artificial intelligence, and data management to the facility. 

“This will be the first facility of this size that's being intentionally designed to enable AI to perform research and development in materials and manufacturing at the same time,” said Stebner, “setting up GTMI as not just a leader in Georgia, but a leader in automation and AI in manufacturing across the country.”

AMPF: A Catalyst for Collaboration

Located just north of Georgia Tech’s main campus, APMF is a 20,000-square-foot facility serving as a teaching laboratory, technology test bed, and workforce development space for manufacturing innovations.

“The pilot facility,” says Stebner, “is meant to be a place where stakeholders in academic research, government, industry, and workforce development can come together and develop both the workforce that is needed for future technologies, as well as mature, de-risk, and develop business cases for new technologies — proving them out to the point where it makes sense for industry to pick them up.”

In addition to serving as the flagship facility for GTMI research and the state’s Georgia AIM (Artificial Intelligence in Manufacturing) project, the AMPF is a user facility accessible to Georgia Tech’s industry partners as well as the Institute’s faculty, staff, and students.

“We have all kinds of great capabilities and technologies, plus staff that can train students, postdocs, and faculty on how to use them,” said Stebner, who also serves as co-director of the GTMI-affiliated Georgia AIM project. “It creates a unique asset for Georgia Tech faculty, staff, and students.”

Bringing AI and Automation to the Forefront

The renovation of APMF is a key component of the $65 million grant, awarded to Georgia Tech by the U.S. Department of Commerce’s Economic Development Administration in 2022, which gave rise to the Georgia AIM project. With over $23 million in support from Georgia AIM, the improved facility will feature new workforce training programs, personnel, and equipment. 

Set to complete in Spring 2026, the Institute’s investment of $16 million supports construction that will roughly triple the size of the facility — and work to address a major roadblock for incorporating AI and automation into manufacturing practices: data.

“There’s a lot of work going on across the world in using machine learning in engineering problems, including manufacturing, but it's limited in scale-up and commercial adoption,” explained Stebner. 

Machine learning algorithms have the potential to make manufacturing more efficient, but they need a lot of reliable, repeatable data about the processes and materials involved to be effective. Collecting that data manually is monotonous, costly, and time-consuming.

“The idea is to automate those functions that we need to enable AI and machine learning” in manufacturing, says Stebner. “Let it be a facility where you can imagine new things and push new boundaries and not just be stuck in demonstrating concepts over and over again.”

To make that possible, the expanded facility will couple AI and data management with robotic automation.

“We're going to be able to demonstrate automation from the very beginning of our process all the way through the entire ecosystem of manufacturing,” said Steven Sheffield, GTMI’s senior assistant director of research operations.

“This expansion — no one else has done anything like it,” added Steven Ferguson, principal research scientist with GTMI and managing director of Georgia AIM. “We will have the leading facility for demonstrating what a hyperconnected and AI-driven manufacturing enterprise looks like. We’re setting the stage for Georgia Tech to continue to lead in the manufacturing space for the next decade and beyond.”

Hepatic, or liver, disease affects more than 100 million people in the U.S. About 4.5 million adults (1.8%) have been diagnosed with liver disease, but it is estimated that between 80 and 100 million adults in the U.S. have undiagnosed fatty liver disease in varying stages. Over time, undiagnosed and untreated hepatic diseases can lead to cirrhosis, a severe scarring of the liver that cannot be reversed. 

Most hepatic diseases are chronic conditions that will be present over the life of the patient, but early detection improves overall health and the ability to manage specific conditions over time. Additionally, assessing patients over time allows for effective treatments to be adjusted as necessary. The standard protocol for diagnosis, as well as follow-up tissue assessment, is a biopsy after the return of an abnormal blood test, but biopsies are time-consuming and pose risks for the patient. Several non-invasive imaging techniques have been developed to assess the stiffness of liver tissue, an indication of scarring, including magnetic resonance elastography (MRE).

MRE combines elements of ultrasound and MRI imaging to create a visual map showing gradients of stiffness throughout the liver and is increasingly used to diagnose hepatic issues. MRE exams, however, can fail for many reasons, including patient motion, patient physiology, imaging issues, and mechanical issues such as improper wave generation or propagation in the liver. Determining the success of MRE exams depends on visual inspection of technologists and radiologists. With increasing work demands and workforce shortages, providing an accurate, automated way to classify image quality will create a streamlined approach and reduce the need for repeat scans. 

Professor Jun Ueda in the George W. Woodruff School of Mechanical Engineering and robotics Ph.D. student Heriberto Nieves, working with a team from the Icahn School of Medicine at Mount Sinai, have successfully applied deep learning techniques for accurate, automated quality control image assessment. The research, “Deep Learning-Enabled Automated Quality Control for Liver MR Elastography: Initial Results,” was published in the Journal of Magnetic Resonance Imaging.

Using five deep learning training models, an accuracy of 92% was achieved by the best-performing ensemble on retrospective MRE images of patients with varied liver stiffnesses. The team also achieved a return of the analyzed data within seconds. The rapidity of image quality return allows the technician to focus on adjusting hardware or patient orientation for re-scan in a single session, rather than requiring patients to return for costly and timely re-scans due to low-quality initial images.

This new research is a step toward streamlining the review pipeline for MRE using deep learning techniques, which have remained unexplored compared to other medical imaging modalities.  The research also provides a helpful baseline for future avenues of inquiry, such as assessing the health of the spleen or kidneys. It may also be applied to automation for image quality control for monitoring non-hepatic conditions, such as breast cancer or muscular dystrophy, in which tissue stiffness is an indicator of initial health and disease progression. Ueda, Nieves, and their team hope to test these models on Siemens Healthineers magnetic resonance scanners within the next year.

New research from Georgia Tech is giving scientists more control options over generative artificial intelligence (AI) models in their studies. Greater customization from this research can lead to discovery of new drugs, materials, and other applications tailor-made for consumers.

The Tech group dubbed its method PRODIGY (PROjected DIffusion for controlled Graph Generation). PRODIGY enables diffusion models to generate 3D images of complex structures, such as molecules from chemical formulas. 

Scientists in pharmacology, materials science, social network analysis, and other fields can use PRODIGY to simulate large-scale networks. By generating 3D molecules from multiple graph datasets, the group proved that PRODIGY could handle complex structures.

In keeping with its name, PRODIGY is the first plug-and-play machine learning (ML) approach to controllable graph generation in diffusion models. This method overcomes a known limitation inhibiting diffusion models from broad use in science and engineering.

“We hope PRODIGY enables drug designers and scientists to generate structures that meet their precise needs,” said Kartik Sharma, lead researcher on the project. “It should also inspire future innovations to precisely control modern generative models across domains.” 

PRODIGY works on diffusion models, a generative AI model for computer vision tasks. While suitable for image creation and denoising, diffusion methods are limited because they cannot accurately generate graph representations of custom parameters a user provides.

PRODIGY empowers any pre-trained diffusion model for graph generation to produce graphs that meet specific, user-given constraints. This capability means, as an example, that a drug designer could use any diffusion model to design a molecule with a specific number of atoms and bonds.

The group tested PRODIGY on two molecular and five generic datasets to generate custom 2D and 3D structures. This approach ensured the method could create such complex structures, accounting for the atoms, bonds, structures, and other properties at play in molecules. 

Molecular generation experiments with PRODIGY directly impact chemistry, biology, pharmacology, materials science, and other fields. The researchers say PRODIGY has potential in other fields using large networks and datasets, such as social sciences and telecommunications.

These features led to PRODIGY’s acceptance for presentation at the upcoming International Conference on Machine Learning (ICML 2024). ICML 2024 is the leading international academic conference on ML. The conference is taking place July 21-27 in Vienna.

Assistant Professor Srijan Kumar is Sharma’s advisor and paper co-author. They worked with Tech alumnus Rakshit Trivedi (Ph.D. CS 2020), a Massachusetts Institute of Technology postdoctoral associate.

A new machine learning (ML) model created at Georgia Tech is helping neuroscientists better understand communications between brain regions. Insights from the model could lead to personalized medicine, better brain-computer interfaces, and advances in neurotechnology.

The Georgia Tech group combined two current ML methods into their hybrid model called MRM-GP (Multi-Region Markovian Gaussian Process). 

Neuroscientists who use MRM-GP learn more about communications and interactions within the brain. This in turn improves understanding of brain functions and disorders.

“Clinically, MRM-GP could enhance diagnostic tools and treatment monitoring by identifying and analyzing neural activity patterns linked to various brain disorders,” said Weihan Li, the study’s lead researcher. 

“Neuroscientists can leverage MRM-GP for its robust modeling capabilities and efficiency in handling large-scale brain data.” 

MRM-GP reveals where and how communication travels across brain regions. 

The group tested MRM-GP using spike trains and local field potential recordings, two kinds of measurements of brain activity. These tests produced representations that illustrated directional flow of communication among brain regions. 

Experiments also disentangled brainwaves, called oscillatory interactions, into organized frequency bands. MRM-GP’s hybrid configuration allows it to model frequencies and phase delays within the latent space of neural recordings.

MRM-GP combines the strengths of two existing methods: the Gaussian process (GP) and linear dynamical systems (LDS). The researchers say that MRM-GP is essentially an LDS that mirrors a GP.

LDS is a computationally efficient and cost-effective method, but it lacks the power to produce representations of the brain. GP-based approaches boost LDS's power, facilitating the discovery of variables in frequency bands and communication directions in the brain.

Converting GP outputs into an LDS is a difficult task in ML. The group overcame this challenge by instilling separability in the model’s multi-region kernel. Separability establishes a connection between the kernel and LDS while modeling communication between brain regions.

Through this approach, MRM-GP overcomes two challenges facing both neuroscience and ML fields. The model helps solve the mystery of intraregional brain communication. It does so by bridging a gap between GP and LDS, a feat not previously accomplished in ML.

“The introduction of MRM-GP provides a useful tool to model and understand complex brain region communications,” said Li, a Ph.D. student in the School of Computational Science and Engineering (CSE). 

“This marks a significant advancement in both neuroscience and machine learning.”

Fellow doctoral students Chengrui Li and Yule Wang co-authored the paper with Li. School of CSE Assistant Professor Anqi Wu advises the group. 

Each MRM-GP student pursues a different Ph.D. degree offered by the School of CSE. W. Li studies computer science, C. Li studies computational science and engineering, and Wang studies machine learning. The school also offers Ph.D. degrees in bioinformatics and bioengineering.

Wu is a 2023 recipient of the Sloan Research Fellowship for neuroscience research. Her work straddles two of the School’s five research areas: machine learning and computational bioscience. 

MRM-GP will be featured at the world’s top conference on ML and artificial intelligence. The group will share their work at the International Conference on Machine Learning (ICML 2024), which will be held July 21-27 in Vienna. 

ICML 2024 also accepted for presentation a second paper from Wu’s group intersecting neuroscience and ML. The same authors will present A Differentiable Partially Observable Generalized Linear Model with Forward-Backward Message Passing.

Twenty-four Georgia Tech faculty from the Colleges of Computing and Engineering will present 40 papers at ICML 2024. Wu is one of six faculty representing the School of CSE who will present eight total papers.

The group’s ICML 2024 presentations exemplify Georgia Tech’s focus on neuroscience research as a strategic initiative.  

Wu is an affiliated faculty member with the Neuro Next Initiative, a new interdisciplinary program at Georgia Tech that will lead research in neuroscience, neurotechnology, and society. The University System of Georgia Board of Regents recently approved a new neuroscience and neurotechnology Ph.D. program at Georgia Tech. 

“Presenting papers at international conferences like ICML is crucial for our group to gain recognition and visibility, facilitates networking with other researchers and industry professionals, and offers valuable feedback for improving our work,” Wu said. 

“It allows us to share our findings, stay updated on the latest developments in the field, and enhance our professional development and public speaking skills.”

From weather prediction to drug discovery, math powers the models used in computer simulations. To help these vital tools with their calculations, global experts recently met at Georgia Tech to share ways to make math easier for computers.

Tech hosted the 2024 International Conference on Preconditioning Techniques for Scientific and Industrial Applications (Precond 24), June 10-12. 

Preconditioning accelerates matrix computations, a kind of math used in most large-scale models. These computer models become faster, more efficient, and more accessible with help from preconditioned equations.

“Preconditioning transforms complex numerical problems into more easily solved ones,” said Edmond Chow, a professor at Georgia Tech and co-chair of Precond 24’s local organization and program committees. 

“The new problem wields a better condition number, giving rise to the name preconditioning.”

Researchers from 13 countries presented their work through 20 mini-symposia and seven invited talks at Precond 24. Their work showcased the practicality of preconditioners. 

Vandana Dwarka, an assistant professor at Delft University of Technology, shared newly developed preconditioners for electromagnetic simulations. This technology can be used in further applications ranging from imaging to designing nuclear fusion devices.

Xiaozhe Hu presented a physics-based preconditioner that simulates biophysical processes in the brain, such as blood flow and metabolic waste clearance. Hu brought this research from Tufts University, where he is an associate professor.

Tucker Hartland, a postdoctoral researcher at Lawrence Livermore National Laboratory, discussed preconditioning in contact mechanics. This work improves the modeling of interactions between physical objects that touch each other. Many fields stand to benefit from Hartland’s study, including mechanical engineering, civil engineering, and materials science.

A unique aspect of this year’s conference was an emphasis on machine learning (ML). Between a panel discussion, tutorial, and several talks, experts detailed how to employ ML for preconditioning and how preconditioning can train ML models.

Precond 24 invited seven speakers from institutions around the world to share their research with conference attendees. The presenters were: 

• Monica Dessole, CERN, Switzerland
• Selime Gurol, CERFACS, France
• Alexander Heinlein, Delft University of Technology, Netherlands
• Rui Peng Li, Lawrence Livermore National Laboratory, USA 
• Will Pazner, Portland State University, USA 
• Tyrone Rees, Science and Technology Facilities Council, UK
• Jacob B. Schroder, University of New Mexico, USA

Along with hosting Precond 24, several Georgia Tech researchers participated in the conference through presentations. 

Ph.D. students Hua Huang and Shikhar Shah each presented a paper on the conference’s first day. Alumnus Srinivas Eswar (Ph.D. CS 2022) returned to Atlanta to share research from his current role at Argonne National Laboratory. Chow chaired the ML panel and a symposium on preconditioners for matrices.

“It was an engaging and rewarding experience meeting so many people from this very tight-knit community,” said Shah, who studies computational science and engineering (CSE). “Getting to see talks close to my research provided me with a lot of inspiration and direction for future work.”

Precond 2024 was the thirteenth meeting of the conference, which occurs every two years. 

The conference returned to Atlanta this year for the first time since 2005. Atlanta joins Minneapolis as one of only two cities in the world to host Precond more than once. Precond 24 marked the sixth time the conference met in the U.S. 

Georgia Tech and Emory University’s Department of Mathematics organized and sponsored Precond 24. The U.S. Department of Energy Office of Science co-sponsored the conference with Tech and Emory. 

Georgia Tech entities swarmed together in support of Precond 24. The Office of the Associate Vice President for Research Operations and Infrastructure, College of Computing, and School of CSE co-sponsored the conference.

“The enthusiasm at the conference has been very gratifying. So many people organized sessions at the conference and contributed to the very strong attendance,” Chow said. 

“This is a testament to the continued importance of preconditioning and related numerical methods in a rapidly changing technological world.”

Work done by Georgia AIM (Artificial Intelligence in Manufacturing) is translating into success stories across the state. Recently, these success stories framed another achievement: Helping to host Vice President Kamala Harris as she kicked off her Economic Opportunity Tour in Atlanta at the end of April.

The multi-state tour was designed to showcase ways the Biden-Harris administration has built economic opportunity, supported communities, and is investing in traditionally underserved areas. Georgia AIM is an example of this, as it helps to expand technology training, job opportunities and advances for manufacturing across the state. Along with Georgia AIM, the Georgia Minority Business Development Agency Business Center (Georgia MBC), and Southeast Business Hub, programs of Georgia Tech’s Enterprise Innovation Institute, also attended the event at the Georgia International Convention Center, near Hartsfield-Jackson Atlanta International Airport.

“This event was a great opportunity to introduce the vice president to the work of Georgia AIM,” said Donna Ennis, co-director of Georgia AIM, which works to drive adoption of AI in U.S. manufacturing. “We were founded as part of the federal government’s Build Back Better plan. It’s important for her to see how we are putting the grant to work to deliver equity in artificial intelligence for manufacturing in Georgia.”

Prior to the arrival of Vice President Harris, attendees could visit tables set up in the entry hall and learn about a number of organizations, from banks to nonprofits to governmental agencies, that are working to level the playing field for underserved Georgians. Attendees included representatives from the Environmental Protection Agency, Rise, and Brunswick Job Corps Center.

The Georgia AIM table, staffed by Ryan Scott, the community engagement manager, and Kyle Saleeby, research engineer with Georgia Tech Manufacturing Institute (GTMI), was a popular stop, thanks to the tabletop “cobot” showing how robotics can be used in manufacturing and an array of 3-D printed industrial materials.

The program featured a conversation with Harris and financial literacy and business advice podcasters Rashad Bilal and Troy Millings, from Earn Your Leisure. The podcast has an audience of about 2 million people, a majority of whom are Black. Harris spoke to the crowd of approximately 400 people about the administration’s focus on access to capital for minority small businesses and entrepreneurs.

“One of the compelling reasons for me to start this tour now,” Harris said, “is to ask all the leaders here for help in getting the word out about what is available to entrepreneurs and small businesses. Because we are in the process of putting a lot of money in the streets of America.”

Some of those funds have gone to Enterprise Innovation Institute programs, including $65 million for Georgia AIM.

Georgia senators Jon Ossoff and Raphael Warnock and Rep. Nikema Williams also spoke at the event. Prior to the event, they joined Harris at the Russell Innovation Center for Entrepreneurs(RICE), a partner project with Georgia AIM. RICE is developing a mobile lab with researchers at the University of Georgia College of Engineering that will showcase AI-based technologies to communities across the state.

“It was exciting to hear first-hand about the administration’s commitment to equity in small businesses and entrepreneurship,” Ennis said. “It dovetails perfectly with the commitment of the programs of the Enterprise Innovation Institute.”
