Time Weaver: A Conditional Time Series Generation Model

no code implementations5 Mar 2024 Sai Shankar Narasimhan, Shubhankar Agarwal, Oguzhan Akcin, Sujay Sanghavi, Sandeep Chinchali

Current approaches to time series generation often ignore this paired metadata, and its heterogeneity poses several practical challenges in adapting existing conditional generation approaches from the image, audio, and video domains to the time series domain.

Symbolic Regression on Sparse and Noisy Data with Gaussian Processes

no code implementations20 Sep 2023 Junette Hsin, Shubhankar Agarwal, Adam Thorpe, Luis Sentis, David Fridovich-Keil

To overcome this, we combine Gaussian process regression with a sparse identification of nonlinear dynamics (SINDy) method to denoise the data and identify nonlinear dynamical equations.

Data Games: A Game-Theoretic Approach to Swarm Robotic Data Collection

no code implementations7 Mar 2023 Oguzhan Akcin, Po-han Li, Shubhankar Agarwal, Sandeep Chinchali

Instead, we propose a cooperative data sampling strategy where geo-distributed AVs collaborate to collect a diverse ML training dataset in the cloud.

Robust Forecasting for Robotic Control: A Game-Theoretic Approach

no code implementations22 Sep 2022 Shubhankar Agarwal, David Fridovich-Keil, Sandeep P. Chinchali

In order to model real-world factors affecting future forecasts, we introduce the notion of an adversary, which perturbs observed historical time series to increase a robot's ultimate control cost.

Imitative Planning using Conditional Normalizing Flow

no code implementations31 Jul 2020 Shubhankar Agarwal, Harshit Sikchi, Cole Gulino, Eric Wilkinson, Shivam Gautam

A popular way to plan trajectories in dynamic urban scenarios for Autonomous Vehicles is to rely on explicitly specified and hand crafted cost functions, coupled with random sampling in the trajectory space to find the minimum cost trajectory.
