Sruthi Sudhakar

I am a second-year PhD student at Columbia University advised by Carl Vondrick and Richard Zemel. My work is supported by the NSF Graduate Research Fellowship. Previously, I completed my B.S. in Computer Science at Georgia Tech where I worked on Algorithmic Fairness advised by Judy Hoffman

I have had the opportunity to intern at Microsoft Research (2022) with Vibhav Vineet and Neel Joshi. I have spent 3 summers working as a Software Engineering Intern with Bloomberg and Microsoft. I am also an active mobile app development volunteer for YogaSangeeta.

In my free time, I enjoy classical indian dancing and spending time with friends and family. Feel free to email me to chat about research, grad school applications, or life!

I'm interested in enabling agents to build representations of their environment and act in the world by learning from offline data and real-world interactions. Building such systems raises many facinating learning questions that I am interested in exploring including perception, generalization, compositionality, and explainability.

Dreamitate is a visuomotor policy learning framework that synthesize videos of humans using tools to complete a task, tracks the tool, and executes the trajectory on the robot to accomplish the task in the real-world.

PaperBot directly learns to design and use a tool in the real world using paper without human intervention.

We propose learning to model interactions through a novel form of visual conditioning: hands. Hands are a natural way to specify control through actions such as grasping, pulling, pushing, etc. Given an input image and a representation of a hand interacting with the scene, our approach, CoSHAND, synthesizes a depiction of what the scene would look like after the interaction has occurred.

We study factors of variation in 3D model quality between simulated and real data to determine what factors are important for computer vision model performanc. To do so, we create a new YCB-Real and digital twin YCB-Synthetic dataset to study adaptation and generalization in controlled environments.

ICON2 leverages prior knowledge on the deficiencies of object detection systems to identify performance discrepancies across sub-populations, compute correlations between these potential confounders and a given sensitive attribute, and control for the most likely confounders to obtain a more reliable estimate of model bias.

TADeT: A targeted alignment strategy for debiasing transformers that aims to discover and remove bias primarily from query matrix features.

UDIS identifies subpopulations via hierarchical clustering of dataset embeddings and surfaces systematic failure modes by visualizing low performing clusters along with their gradient-weighted class-activation maps.
