Sudeep Dasari

I'm an undergraduate Electrical Engineering and Computer Science student at UC Berkeley. On campus, you can usually find me at Berkeley Aritificial Intelligence Research (BAIR) labs - where I work with Professor Sergey Levine on deep reinforcement learning/machine learning research . Previously, I worked at Los Alamos National Laboratory with Dr. David Mascareñas on cyber-phsyical systems research.

Research

I'm interested in computer vision, machine learning, robotics, statistics, and generative modelling. I aspire to push the boundaries of what robots can do with visual data given minimal supervision, and create new ways for them to interact more naturally with humans.

We demonstrate that video prediction models - generative models trained on autonomously collected data of robots interacting with their environment - can be used for vision based robotic control.

Robustness via Retrying

While visual prediction planners can acheive a wide variety of manipulation tasks, they often fail by loosing track of the object. We propose a self-supervised registration algorithm which allows even imperfect planners to retry continuously until they succeed.

Domain Adaptive Meta-Learning

Domain Adaptive Meta-Learning allows for one-shot learning under domain shift. Using our policy, robots can to learn to manipulate unseen objects by referring to a single video demonstration of a human performing a task with said object.

Deep Robotic Learning using Visual Imagination & Meta-Learning

project page, press coverage

A key, unsolved challenge for learning with real robotic systems is the ability to acquire vision-based behaviors from raw RGB images. We present two approaches to this goal that we demonstrate: first, learning task-agnostic visual models for planning and second, learning to quickly adapt to new objects and environments using meta-imitation learning.

Light Field Imaging of Three-Dimensional Structural Dynamics

Society for Experimental Mechanics: IMAC, 2018

Cameras offer a way to perform low cost and non-invasive damage detection by analyzing a structure's vibrations. To acheive this goal, we use a light field imager to create a 3D point cloud of vibrating cantilever beams, and then use Principal Component Analysis and Blind Source Seperation to find the beam's mode shapes and frequencies.

A framework for the identification of full-field structural dynamics using sequences of images in the presence of non-ideal operating conditions

Journal of Intelligent Material Systems and Structures, 2017

Recent developments in analyzing structures with raw video streams has great potential for reducing the resources and time required for performing operational modal analysis at very high spatial resolution. We propose a key-point based registration technique to extend this method to settings with large rigid body motion (e.g drone footage).

Efficient Full-Field Vibration Measurements and Operational Modal Analysis Using Neuromorphic Event-Based Imaging

We demonstrate that asynchronous silicon retina imagers can capture structural motion on the microsecond scale in an extremely data-efficient manner.

Fun With Words: Generating Text with Context
Sudeep Dasari, Hankun (Jerry) Zhao, William Zhao, 2018


State of the art machine translation networks can be used for conditional text generation. We leverage the Yelp dataset to train models which generate sensible 1 - 5 star reviews of resteraunts given only the establishment's name.

Non-Linear Raytracing
Sudeep Dasari, Jennifer Wen Hsu, 2017


Most ray-tracing algorithms assume that light travels in a straight line from the camera into the scene. However, there are many cases where a light may travel a non-linear path (e.g mirage). We demonstrate non-linear raytracing can correctly render scenes with mirages and fata-morgana, as well as trace light passing through Gradient Optic Index Lenses.
