Vijay Veerabadran

Hello there! My name is Vijay, and I am a Ph.D. student at the UC San Diego. My research lies in the conjunction of primate vision and machine vision. I am working on developing the next generation of robust computer vision models by taking inspiration from computational principles that underlie primate vision. As a way of closing this loop of neuroscience to better machine learning, my work also involves the application state-of-the-art machine learning techniques to analyze neural data (i.e., machine learning to better neuroscience).

I primarily work with my advisor, Dr. Virginia de Sa at UCSD Cognitive Science, and I actively collaborate with Dr. Terrence Sejnowski at the Salk Institute.

Prior to starting my Ph.D., I spent a wonderful year working at Brown University with Dr. Thomas Serre. In April 2017, I graduated with a bachelors degree in Computer Science and Engineering from SSN College of Engineering, Chennai, India.

Research

My recent work is centered around the development of neurally inspired hierarchical and recurrent architectures with the help of computer vision and optogenetics data. I am interested in computationally reverse-engineering the visual cortex, and thereby utilize these models for relevant computer vision tasks to obtain brain-like robustness and sample efficiency.

Abstract

In this poster, we discuss the identification of early behavioral deficits in the SOD1-G85R mouse model for ALS. We also briefly discuss our automated behavioral monitoring system and its application to efficiently recording and analyzing activities of mice on a massively parallel scale.


Projects

Listed below are a few of my recent research projects for which I have open-sourced my implementation. I have implemented all the below solutions using TensorFlow, my most comfortable framework for implementing neural architectures.

Automated Continuous Behavioral Monitoring using Inception3D
Code / Demo

I worked with Dr. Justin Fallon and Thomas Serre on an automated behavioral monitoring system to complement research in diagnosing neuromotor diseases through video analysis using deep learning.

Automated Video Captioning - Undergraduate thesis
Code / Demo

I developed a sequence-to-sequence deep neural network to generate natural language captions describing input videos. This repository is one of the most popular repositories for video captioning on GitHub.


Talks
Neocognitron: A neural network model for a mechanism of visual pattern recognition - Kunihiko Fukushima, Sei Miyake, Takayuki Ito Slides

I gave an introductory talk on the Neocognitron, the predecessor to Convolutional Neural Networks, at Sanjoy Dasgupta's seminar - CSE 254: Neurally Inspired Unsupervised Learning.

Generative Adversarial Networks and Their Applications Slides

In this talk that I delivered at Artifacia Inc., I presented an introduction to Generative Adversarial Networks and their applications to several cutting-edge computer vision problems.
