Adapting a Foundation Model for Space-based Tasks

no code implementations12 Aug 2024 Matthew Foutter, Praneet Bhoj, Rohan Sinha, Amine Elhafsi, Somrita Banerjee, Christopher Agia, Justin Kruger, Tommaso Guffanti, Daniele Gammelli, Simone D'Amico, Marco Pavone

Foundation models, e. g., large language models, possess attributes of intelligence which offer promise to endow a robot with the contextual understanding necessary to navigate complex, unstructured tasks in the wild.

Real-Time Anomaly Detection and Reactive Planning with Large Language Models

no code implementations11 Jul 2024 Rohan Sinha, Amine Elhafsi, Christopher Agia, Matthew Foutter, Edward Schmerling, Marco Pavone

Foundation models, e. g., large language models (LLMs), trained on internet-scale data possess zero-shot generalization capabilities that make them a promising technology towards detecting and mitigating out-of-distribution failure modes of robotic systems.

Learning Temporal Logic Predicates from Data with Statistical Guarantees

no code implementations15 Jun 2024 Emi Soroka, Rohan Sinha, Sanjay Lall

We present a novel method to learn temporal logic predicates from data with finite-sample correctness guarantees.

Closing the Loop on Runtime Monitors with Fallback-Safe MPC

no code implementations15 Sep 2023 Rohan Sinha, Edward Schmerling, Marco Pavone

When we rely on deep-learned models for robotic perception, we must recognize that these models may behave unreliably on inputs dissimilar from the training data, compromising the closed-loop system's safety.

A System-Level View on Out-of-Distribution Data in Robotics

no code implementations28 Dec 2022 Rohan Sinha, Apoorva Sharma, Somrita Banerjee, Thomas Lew, Rachel Luo, Spencer M. Richards, Yixiao Sun, Edward Schmerling, Marco Pavone

When testing conditions differ from those represented in training data, so-called out-of-distribution (OOD) inputs can mar the reliability of learned components in the modern robot autonomy stack.

Adaptive Robust Model Predictive Control via Uncertainty Cancellation

no code implementations2 Dec 2022 Rohan Sinha, James Harrison, Spencer M. Richards, Marco Pavone

We propose a learning-based robust predictive control algorithm that compensates for significant uncertainty in the dynamics for a class of discrete-time systems that are nominally linear with an additive nonlinear component.

Online Distribution Shift Detection via Recency Prediction

no code implementations17 Nov 2022 Rachel Luo, Rohan Sinha, Yixiao Sun, Ali Hindy, Shengjia Zhao, Silvio Savarese, Edward Schmerling, Marco Pavone

When deploying modern machine learning-enabled robotic systems in high-stakes applications, detecting distribution shift is critical.

Adaptive Robust Model Predictive Control with Matched and Unmatched Uncertainty

no code implementations16 Apr 2021 Rohan Sinha, James Harrison, Spencer M. Richards, Marco Pavone

We propose a learning-based robust predictive control algorithm that compensates for significant uncertainty in the dynamics for a class of discrete-time systems that are nominally linear with an additive nonlinear component.
