Competitive Facility Location under Random Utilities and Routing Constraints

no code implementations7 Mar 2024 Hoang Giang Pham, Tien Thanh Dam, Ngan Ha Duong, Tien Mai, Minh Hoang Ha

To tackle this problem, we explore three types of valid cuts, namely, outer-approximation and submodular cuts to handle the nonlinear objective function, as well as sub-tour elimination cuts to address the complex routing constraints.

SubIQ: Inverse Soft-Q Learning for Offline Imitation with Suboptimal Demonstrations

no code implementations20 Feb 2024 Huy Hoang, Tien Mai, Pradeep Varakantham

Most of the existing offline IL methods developed for this setting are based on behavior cloning or distribution matching, where the aim is to match the occupancy distribution of the imitation policy with that of the expert policy.

Imitate the Good and Avoid the Bad: An Incremental Approach to Safe Reinforcement Learning

1 code implementation16 Dec 2023 Huy Hoang, Tien Mai, Pradeep Varakantham

In an exhaustive set of experiments, we demonstrate that our approach is able to outperform top benchmark approaches for solving Constrained RL problems, with respect to expected cost, CVaR cost, or even unknown cost constraints.

Inverse Factorized Q-Learning for Cooperative Multi-agent Imitation Learning

no code implementations10 Oct 2023 The Viet Bui, Tien Mai, Thanh Hong Nguyen

This paper concerns imitation learning (IL) (i. e, the problem of learning to mimic expert behaviors from demonstrations) in cooperative multi-agent systems.

Network-based Representations and Dynamic Discrete Choice Models for Multiple Discrete Choice Analysis

no code implementations7 Jun 2023 Hung Tran, Tien Mai

In this paper, to address this, we propose a random utility maximization (RUM) based model that considers each subset of choice alternatives as a composite alternative, where individuals choose a subset according to the RUM framework.

Solving Richly Constrained Reinforcement Learning through State Augmentation and Reward Penalties

no code implementations27 Jan 2023 Hao Jiang, Tien Mai, Pradeep Varakantham, Minh Huy Hoang

Constrained Reinforcement Learning has been employed to enforce safety constraints on policy through the use of expected cost constraints.

Imitating Opponent to Win: Adversarial Policy Imitation Learning in Two-player Competitive Games

no code implementations30 Oct 2022 The Viet Bui, Tien Mai, Thanh H. Nguyen

The core idea of our new algorithm is to create a new imitator to imitate the victim agent's policy while the adversarial policy will be trained not only based on interactions with the victim agent but also based on feedback from the imitator to forecast victim's intention.

Weighted Maximum Entropy Inverse Reinforcement Learning

no code implementations20 Aug 2022 The Viet Bui, Tien Mai, Patrick Jaillet

We study inverse reinforcement learning (IRL) and imitation learning (IM), the problems of recovering a reward or policy function from expert's demonstrated trajectories.

Scalable Distributional Robustness in a Class of Non Convex Optimization with Guarantees

no code implementations31 May 2022 Avinandan Bose, Arunesh Sinha, Tien Mai

Distributionally robust optimization (DRO) has shown lot of promise in providing robustness in learning as well as sample based optimization problems.

Estimation of Recursive Route Choice Models with Incomplete Trip Observations

no code implementations27 Apr 2022 Tien Mai, The Viet Bui, Quoc Phong Nguyen, Tho V. Le

This work concerns the estimation of recursive route choice models in the situation that the trip observations are incomplete, i. e., there are unconnected links (or nodes) in the observations.

Robust Entropy-regularized Markov Decision Processes

no code implementations31 Dec 2021 Tien Mai, Patrick Jaillet

Stochastic and soft optimal policies resulting from entropy-regularized Markov decision processes (ER-MDP) are desirable for exploration and imitation learning applications.

A Relation Analysis of Markov Decision Process Frameworks

no code implementations18 Aug 2020 Tien Mai, Patrick Jaillet

We show that the entropy-regularized MDP is equivalent to a stochastic MDP model, and is strictly subsumed by the general regularized MDP.

Inverse Reinforcement Learning with Missing Data

no code implementations16 Nov 2019 Tien Mai, Quoc Phong Nguyen, Kian Hsiang Low, Patrick Jaillet

We consider the problem of recovering an expert's reward function with inverse reinforcement learning (IRL) when there are missing/incomplete state-action pairs or observations in the demonstrated trajectories.
