Scalable Decision-Making in Stochastic Environments through Learned Temporal Abstraction

1 code implementation28 Feb 2025 Baiting Luo, Ava Pettet, Aron Laszka, Abhishek Dubey, Ayan Mukhopadhyay

Notably, across tasks ranging from continuous control with inherently stochastic dynamics to high-dimensional robotic hand manipulation, L-MAP significantly outperforms existing model-based methods and performs on-par with strong model-free actor-critic baselines, highlighting the effectiveness of the proposed approach in planning in complex and stochastic environments with high-dimensional action spaces.

Decision Making in Non-Stationary Environments with Policy-Augmented Search

1 code implementation6 Jan 2024 Ava Pettet, Yunuo Zhang, Baiting Luo, Kyle Wray, Hendrik Baier, Aron Laszka, Abhishek Dubey, Ayan Mukhopadhyay

In this paper, we introduce \textit{Policy-Augmented Monte Carlo tree search} (PA-MCTS), which combines action-value estimates from an out-of-date policy with an online search using an up-to-date model of the environment.

Dynamic Simplex: Balancing Safety and Performance in Autonomous Cyber Physical Systems

1 code implementation20 Feb 2023 Baiting Luo, Shreyas Ramakrishna, Ava Pettet, Christopher Kuhn, Gabor Karsai, Ayan Mukhopadhyay

To address these limitations, we propose a dynamic simplex strategy with an online controller switching logic that allows two-way switching.
