Welcome The Agency, the undergraduate AI/ML club at Georgia Tech


The Agency is an undergraduate AI/ML club at Georgia Tech. Here is a short introduction to The Agency, from the members of this club.

We are a hub for connecting undergraduate students with the machine learning community at Tech. Every week, we present talks on machine learning/artificial intelligence. These range from undergraduates lecturing on interesting concepts in the field to professors/graduate students presenting their research.

Beyond our weekly lectures, we give people the resources to do machine learning research. For instance, we organize larger events, such as our recent workshop on TensorFlow, and offer dedicated computing resources for undergraduates to train learning models. We also host a deep learning paper reading group that meets every two weeks.agencyblurbformlgt_pdf__page_2_of_2_

Furthermore, we also work on projects such as Buzzmobile, an autonomous vehicle modeled after the Rambling Wreck. Buzzmobile has a purely reactive control architecture, built entirely in ROSpy. Other shorter-term projects we’ve worked on in the past include various game AIs and applications of different AI and ML algorithms and models, such as RNNs for lyrics generation or simulated annealing for prettifying graphs.

Many of our members and officers are already doing undergraduate research in the field of Machine Learning. We are hoping to grow this community of undergraduate researchers by providing our members with the resources of and connections to ML labs (or labs that can use ML).

If you’d like to know more about us, please visit our website, join our Slack, or like our Facebook page. Or feel free to get in touch with our External Relations officer, Raphael Gontijo Lopes.

We welcome The Agency to ML@GT family.

Jacob Eisentein (Georgia Tech) "Two new machine learning approaches for text classification"

Speaker: Jacob Eisenstein

Title: Two new machine learning approaches for text classification


Text document classification is one of the most well studied applications of machine learning. Yet this technology is still limited by practical difficulties and invalid underlying assumptions.

First, many people who want text classifiers do not have the time or resources to annotate a dataset. They often employ a heuristic alternative: they create word lists for each label class, and then perform prediction by selecting the class whose list matches the largest number of words in the text. This heuristic is theoretically unjustified, and mistakenly assigns the same importance to every word in the list. I show that list-based classification can be viewed as a (very!) special case of Naive Bayes. Based on this analysis, it is possible to estimate weights for each word without supervision, using the method-of-moments.

Second, machine learning approaches to text classification nearly always begin with an IID assumption. Yet words can mean different things to different people, raising the possibility for misunderstandings even in human-human conversation. One potential solution is to relax the IID assumption by personalizing text classifiers to the author. An apparent roadblock is the challenge of obtaining labeled data for each author. I will present a method that sidesteps this requirement by relying on the sociological theory of homophily, which states that people who are socially connected tend to share personal traits. This idea can be formalized by estimating node embeddings for each individual in a social network, and then using these embeddings to drive a social attentional mechanism in a neural ensemble classifier. The resulting system obtains significant improvements on sentiment analysis in Twitter. This project is joint work with Yi Yang.

IDEaS and ARC DL: Jon Kleinberg "Human Decisions and Machine Predictions"

IDEaS and ARC Distinguished Lecture

As part of ARC10: Celebrating 10 years of the Algorithms and Randomness Center

Monday, October 24 at 10 AM

Jon Kleinberg (Cornell University)

Human Decisions and Machine Predictions

Klaus Advanced Computing Building Room 1116


An increasing number of domains are providing us with detailed trace data on human decisions, often made by experts with deep experience in the subject matter. This provides an opportunity to use machine-learning prediction algorithms to ask several families of questions -- not only about the extent to which algorithms can outperform expert-level human decision-making in specific domains, but also whether we can use algorithms to analyze the nature of the errors made by human experts, to predict which instances will be hardest for these experts, and to explore some of the ways in which prediction algorithms can serve as supplements to human decision-making in different applications.  In this talk, I'll explore this theme by drawing on a line of recent projects; all are joint with Sendhil Mullainathan, and include collaborations with Ashton Anderson, Himabindu Lakkaraju, Jure Leskovec, Annie Liang, and Jens Ludwig. 


Jon Kleinberg is the Tisch University Professor in the Departments of Computer Science and Information Science at Cornell University. His research focuses on issues at the interface of networks and information, with an emphasis on the social and information networks that underpin the Web and other on-line media. He is a member of the National Academy of Sciences, the National Academy of Engineering, and the American Academy of Arts and Science; and he is the recipient of research fellowships from the MacArthur, Packard, Simons, and Sloan Foundations, as well as awards including the Nevanlinna Prize, the Harvey Prize, the Newell Award, and the ACM-Infosys Foundation Award in the Computing Sciences.

Welcome to ML@GT by the Director

Welcome to ML@GT, a new interdisciplinary research center at Georgia Tech dedicated to the study and application of machine learning—one of the fastest developing research areas impacting computing, engineering, sciences and many other disciplines.

What makes machine learning so important? If you’re visiting this site, you probably already have an answer to that question. But for those new to the field, think of it this way: For all their power and ever-increasing capabilities, computers historically have actually been pretty dumb. They tended to do only what you explicitly told them to do. Of course, ever more sophisticated software (running on ever more sophisticated machines) could carry a lot of instructions, but at the end of day, humans still needed to tell the machine exactly how to respond to each individual circumstance and how to make inferences.

Machine learning changes all that. Now we can provide computers not just with instructions but with the means to learn from their observations and the data they collect. In effect, we enable computers to response to circumstances “on the ground”—or in outer space, or somewhere along the supply chain, or up in the cloud in the midst of billions of terabytes of constantly changing data.

At Georgia Tech, we recognize machine learning to be a game-changer not just in computer science, but in a broad range of scientific, engineering, and business disciplines and practices. And the faculty membership of ML@GT reflects that broad thinking, with dozens of affiliated researchers from the Institute’s Colleges of Computing, Engineering, Sciences, Business, and other areas.

I invite you to peruse our new website to get a feel for what machine learning can do and how Georgia Tech will study and apply it. Whether you already work in machine learning or are a student interested to learn how you can incorporate ML into your studies, we’d like to work with you.

Feel feel to drop us a note. We can all help make the machines all around us just a little bit smarter.
