Srikar Yellapragada

I am a PhD student in the Computer Science department at Stony Brook University, advised by Dimitris Samaras My research is focused on Computer vision. Before this, I was a Software Engineer at Bloomberg LP; our team built an ETL pipeline for the ingestion of third party data.

In 2020, I obtained my Masters in Computer Science from NYU, where I worked with Kyunghyun Cho's group on Similarity of Neural Networks, and interned at IBM Watson Health.

Previously, I obtained a B.Tech in Electrical Engineering from Indian Institute of Technology, Hyderabad, where I worked with Sumohana Channappayya on Image Processing. I interned at Video Analytics Lab, IISc Bangalore.

In my free time, I enjoy playing video games. I'm a big fan of strategy games, such as Dota 2 and Age of Empires 2.

We build a text conditioned LDM for histopathology using GPT summarized text reports and CLIP embeddings.

Conditional Generation from Unconditional Diffusion Models using Denoiser Representations
Alexandros Graikos, Srikar Yellapragada, Dimitris Samaras
In British Machine Vision Conference (BMVC), 2023
paper / code / poster

We condition unconditional models in limited data scenarios using an auxiliary network built upon denoiser representations.

Are the proposed similarity metrics also a measure of functional similarity?
Manikanta Srikar Yellapragada
Masters Thesis, 2020
paper

Short ans: NO.
Existing representation similarity metrics cannot fully capture the output (functional) similiarity of a neural network.
