Decentralized Input and State Estimation for Multi-agent System with Dynamic Topology and Heterogeneous Sensor Network

no code implementations30 Sep 2024 Zida Wu, Ankur Mehta

A crucial challenge in decentralized systems is state estimation in the presence of unknown inputs, particularly within heterogeneous sensor networks with dynamic topologies.

Population-aware Online Mirror Descent for Mean-Field Games by Deep Reinforcement Learning

no code implementations6 Mar 2024 Zida Wu, Mathieu Lauriere, Samuel Jia Cong Chua, Matthieu Geist, Olivier Pietquin, Ankur Mehta

Mean Field Games (MFGs) have the ability to handle large-scale multi-agent systems, but learning Nash equilibria in MFGs remains a challenging task.

Cost-Driven Hardware-Software Co-Optimization of Machine Learning Pipelines

no code implementations11 Oct 2023 Ravit Sharma, Wojciech Romaszkan, Feiqian Zhu, Puneet Gupta, Ankur Mehta

We perform this hardware/software co-design from the cost, latency, and user-experience perspective, and develop a set of guidelines for optimal system design and model deployment for the most cost-constrained platforms.

User Based Design and Evaluation Pipeline for Indoor Airships

no code implementations19 Oct 2021 Zhaoliang Zheng, Jiahao Li, Parth Agrawal, Zhao Lei, Aaron John-Sabu, Ankur Mehta

Designing a controllable airship for non-expert users or preemptively evaluating the performance of desired airships has always been a very challenging problem.

Computational Design and Fabrication of Corrugated Mechanisms from Behavioral Specifications

no code implementations10 Nov 2020 Chang Liu, Wenzhong Yan, Ankur Mehta

Based on an equivalent plate model, we develop and validate analytical formulas for the behavioral specifications of OADLC mechanisms; the analytical formulas can be described as expressions of design parameters.

Unsupervised Monocular Depth Learning with Integrated Intrinsics and Spatio-Temporal Constraints

no code implementations2 Nov 2020 Kenny Chen, Alexandra Pogue, Brett T. Lopez, Ali-akbar Agha-mohammadi, Ankur Mehta

Monocular depth inference has gained tremendous attention from researchers in recent years and remains as a promising replacement for expensive time-of-flight sensors, but issues with scale acquisition and implementation overhead still plague these systems.

Risk-Averse MPC via Visual-Inertial Input and Recurrent Networks for Online Collision Avoidance

no code implementations28 Jul 2020 Alexander Schperberg, Kenny Chen, Stephanie Tsuei, Michael Jewett, Joshua Hooks, Stefano Soatto, Ankur Mehta, Dennis Hong

In this paper, we propose an online path planning architecture that extends the model predictive control (MPC) formulation to consider future location uncertainties for safer navigation through cluttered environments.

Toward Synergic Learning for Autonomous Manipulation of Deformable Tissues via Surgical Robots: An Approximate Q-Learning Approach

no code implementations8 Oct 2019 Sahba Aghajani Pedram, Peter Walker Ferguson, Changyeob Shin, Ankur Mehta, Erik P. Dutson, Farshid Alambeigi, Jacob Rosen

We propose using a linear approximate Q-learning method in which human knowledge contributes to selecting useful yet simple features of tissue manipulation while the algorithm learns to take optimal actions and accomplish the task.

Event-Triggered Diffusion Kalman Filters

1 code implementation1 Nov 2017 Amr Alanwar, Hazem Said, Ankur Mehta, Matthias Althoff

Distributed state estimation strongly depends on collaborative signal processing, which often requires excessive communication and computation to be executed on resource-constrained sensor nodes.
