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

Learning to Represent Words by how They’re Spelled

A fundamental question in Natural Language Processing (NLP) is how to represent words. If we have a paragraph we want to translate, or a product review we want to determine whether is positive or negative, or a question we want to answer, ultimately the easiest building block to start from is the individual word. The … Continue reading Learning to Represent Words by how They’re Spelled

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").
