Georgia Tech’s Newest AI System Can Mimic Thinking Out Loud and Explain Its Decision to Non-Experts in Real-time

By Upol Ehsan, Ph.D. Student, School of Interactive Computing, Georgia Tech (contributing writer; Joshua Preston, GVU Center) If the power of AI is to be democratized, it needs to be accessible to anyone regardless of their technical abilities. As AI pervades all aspects of our lives, there is a distinct need for human-centered AI design … Continue reading Georgia Tech’s Newest AI System Can Mimic Thinking Out Loud and Explain Its Decision to Non-Experts in Real-time

Learning to Cluster

“Can machines categorize new things by learning how to group similar things together?” The following describes work by Yen-Chang Hsu, Zhaoyang Lv, and Zsolt Kira, which will be presented at the 2018 International Conference on Learning Representations (ICLR) in Vancouver. Read the paper here. Clustering is the task of partitioning data into groups, so that … Continue reading Learning to Cluster

From Object Interactions to Fine-grained Video Understanding

Video understanding tasks such as action recognition and caption generation are crucial for various real-world applications in surveillance, video retrieval, human behavior understanding, etc. In this work, we present a generic recurrent module to detect relationships and interactions between arbitrary object groups for fine-grained video understanding. Our work is applicable to various open domain video … Continue reading From Object Interactions to Fine-grained Video Understanding

The Minds of the New Machines | Research Horizons | Georgia Tech’s Research News

Georgia Tech's Research Horizons Magazine has done a very nice write-up of the ML@GT center, featuring many of our research projects. Machine learning has been around for decades, but the advent of big data and more powerful computers has increased its impact significantly — ­moving machine learning beyond pattern recognition and natural language processing into a … Continue reading The Minds of the New Machines | Research Horizons | Georgia Tech’s Research News

Robust Skill Generalization Using Probabilistic Inference

Everyday skills, such as making your bed or even pressing a doorbell, might seem trivial to us, but are actually quite complicated for today’s robots. Think about your performance the first time you tried a sport.  Did you seek help from a peer or coach? Did you perform better after that? Most probably you answered yes. It … Continue reading Robust Skill Generalization Using Probabilistic Inference

Embodied Question Answering

Embodied Question Answering is a new AI task where an agent is spawned at a random location in a 3D environment and asked a question ("What color is the car?"). In order to answer, the agent must first intelligently navigate to explore the environment, gather information through first-person (egocentric) vision, and then answer the question ("orange").
