Apoorv Umang Saxena

I am a research scientist at Adobe Research, Bangalore with a research focus on NLP and multi-modal machine learning.

Previously I received my PhD from the Department of Computational and Data Sciences (CDS) at the Indian Institute of Science, Bangalore. I was supervised by Prof. Partha Pratim Talukdar.

Prior to graduate school, I received my Bachelor of Engineering (BE Hons.) in Computer Science from Birla Institute of Technology and Science, Pilani (BITS Pilani) in 2015.

Research

I am broadly interested in generative AI (NLP, computer vision) and their applications. In my post-graduate work, I had a specific focus on knowledge graphs (KG) and question answering. In this area, I have tried to improve QA performance by combining pre-trained language models with KG embeddings. I have also worked on making KG embeddings more scalable and easier to apply to downstream tasks. During my undergraduate studies I worked on humanoid robotics and computer vision.

Podcast transcription and highlight generation

I used openai-whisper (along with pyannote and flan-t5) to automatically generate transcripts and highlights for all episodes of The Seen and The Unseen podcast by Amit Varma. These can be browsed at https://apoorvumang.github.io/seenunseen
