Credit vs. Discount-Based Congestion Pricing: A Comparison Study

no code implementations20 Mar 2024 Chih-Yuan Chiu, Devansh Jalota, Marco Pavone

Tolling, or congestion pricing, offers a promising traffic management policy for regulating congestion, but has also attracted criticism for placing outsized financial burdens on low-income users.

Dynamic Tolling in Arc-based Traffic Assignment Models

no code implementations11 Jul 2023 Chih-Yuan Chiu, Chinmay Maheshwari, Pan-Yang Su, Shankar Sastry

We prove that our adaptive learning and marginal pricing dynamics converge to a neighborhood of the socially optimal loads and tolls.

Arc-based Traffic Assignment: Equilibrium Characterization and Learning

no code implementations10 Apr 2023 Chih-Yuan Chiu, Chinmay Maheshwari, Pan-Yang Su, Shankar Sastry

Arc-based traffic assignment models (TAMs) are a popular framework for modeling traffic network congestion generated by self-interested travelers who sequentially select arcs based on their perceived latency on the network.

Scenario-Game ADMM: A Parallelized Scenario-Based Solver for Stochastic Noncooperative Games

no code implementations4 Apr 2023 Jingqi Li, Chih-Yuan Chiu, Lasse Peters, Fernando Palafox, Mustafa Karabag, Javier Alonso-Mora, Somayeh Sojoudi, Claire Tomlin, David Fridovich-Keil

To accommodate this, we decompose the approximated game into a set of smaller games with few constraints for each sampled scenario, and propose a decentralized, consensus-based ADMM algorithm to efficiently compute a generalized Nash equilibrium (GNE) of the approximated game.

Towards Dynamic Causal Discovery with Rare Events: A Nonparametric Conditional Independence Test

1 code implementation29 Nov 2022 Chih-Yuan Chiu, Kshitij Kulkarni, Shankar Sastry

Causal phenomena associated with rare events occur across a wide range of engineering problems, such as risk-sensitive safety analysis, accident analysis and prevention, and extreme value theory.

Pursuit of a Discriminative Representation for Multiple Subspaces via Sequential Games

1 code implementation18 Jun 2022 Druv Pai, Michael Psenka, Chih-Yuan Chiu, Manxi Wu, Edgar Dobriban, Yi Ma

We consider the problem of learning discriminative representations for data in a high-dimensional space with distribution supported on or around multiple low-dimensional linear subspaces.

Simultaneous Localization and Mapping: Through the Lens of Nonlinear Optimization

no code implementations11 Dec 2021 Amay Saxena, Chih-Yuan Chiu, Joseph Menke, Ritika Shrivastava, Shankar Sastry

This work presents an optimization-based framework that unifies these approaches, and allows users to flexibly implement different design choices, e. g., the number and types of variables maintained in the algorithm at each time.

Zeroth-Order Methods for Convex-Concave Minmax Problems: Applications to Decision-Dependent Risk Minimization

no code implementations16 Jun 2021 Chinmay Maheshwari, Chih-Yuan Chiu, Eric Mazumdar, S. Shankar Sastry, Lillian J. Ratliff

Min-max optimization is emerging as a key framework for analyzing problems of robustness to strategically and adversarially generated data.
