Pramod Chunduri

I’m a PhD Candidate in Computer Science at Georgia Tech advised by Prof. Joy Arulraj, where I’m building efficient systems for AI applications, with a particular emphasis on video analytics and large language models (LLM).

My research focuses on accelerating query processing on AI platforms with a goal of achieving low latency and high accuracy. Through my research, I have developed advanced video analytics systems capable of answering complex queries involving multiple objects, actions, and motions in videos. Presently, I am optimizing Retrieval-Augmented Generation (RAG), a state-of-the-art LLM paradigm, to enhance question-answering efficiency.

In addition to my academic pursuits, I gained valuable industry experience as an Applied Scientist Intern at AWS AI Labs, where I built a state-of-the-art tabular QA system leveraging LLMs as task-specific verifiers. I also worked as a Research Scientist Intern at Adobe, where I utilized machine learning to devise personalized video editing tools that recommend optimal highlights and edits from raw footage.

Detection and localization of actions in videos is an important problem in practice. State-of-the-art video analytics systems are unable to efficiently and effectively answer such action queries because actions often involve a complex interaction between objects and are spread across a sequence of frames; detecting and localizing them requires computationally expensive deep neural networks. It is also important to consider the entire sequence of frames to answer the query effectively. In this paper, we present ZEUS, a video analytics system tailored for answering action queries. We present a novel technique for efficiently answering these queries using deep reinforcement learning. ZEUS trains a reinforcement learning agent that learns to adaptively modify the input video segments that are subsequently sent to an action classification network. The agent alters the input segments along three dimensions - sampling rate, segment length, and resolution. To meet the user-specified accuracy target, ZEUS’s query optimizer trains the agent based on an accuracy-aware, aggregate reward function. Evaluation on three diverse video datasets shows that ZEUS outperforms state-of-the-art frame- and window-based filtering techniques by up to 22.1x and 4.7x, respectively. It also consistently meets the user-specified accuracy target across all queries.
