Episodic Reinforcement Learning with Expanded State-reward Space

no code implementations19 Jan 2024 Dayang Liang, Yaru Zhang, Yunlong Liu

As a result, our method is able to simultaneously achieve the full utilization of retrieval information and the better evaluation of state values by a Temporal Difference (TD) loss.

Sequential Action-Induced Invariant Representation for Reinforcement Learning

1 code implementation22 Sep 2023 Dayang Liang, Qihang Chen, Yunlong Liu

Specifically, we propose a Sequential Action--induced invariant Representation (SAR) method, in which the encoder is optimized by an auxiliary learner to only preserve the components that follow the control signals of sequential actions, so the agent can be induced to learn the robust representation against distractions.

Online Learning and Planning in Partially Observable Domains without Prior Knowledge

1 code implementation11 Jun 2019 Yunlong Liu, Jianyang Zheng

How an agent can act optimally in stochastic, partially observable domains is a challenge problem, the standard approach to address this issue is to learn the domain model firstly and then based on the learned model to find the (near) optimal policy.

Combining Offline Models and Online Monte-Carlo Tree Search for Planning from Scratch

no code implementations5 Apr 2019 Yunlong Liu, Jianyang Zheng

Planning in stochastic and partially observable environments is a central issue in artificial intelligence.

Conformation Clustering of Long MD Protein Dynamics with an Adversarial Autoencoder

no code implementations31 May 2018 Yunlong Liu, L. Mario Amzel

Multiple protein states and a large number of microstates associated with folding and with the function of the protein can be observed as conformations sampled in the trajectories.

Selecting Bases in Spectral learning of Predictive State Representations via Model Entropy

no code implementations29 Dec 2016 Yunlong Liu, Hexing Zhu

Predictive State Representations (PSRs) are powerful techniques for modelling dynamical systems, which represent a state as a vector of predictions about future observable events (tests).
