Return to Tradition: Learning Reliable Heuristics with Classical Machine Learning

no code implementations25 Mar 2024 Dillon Z. Chen, Felipe Trevizan, Sylvie Thiébaux

Current approaches for learning for planning have yet to achieve competitive performance against classical planners in several domains, and have poor overall performance.

Efficient Constraint Generation for Stochastic Shortest Path Problems

no code implementations26 Jan 2024 Johannes Schmalz, Felipe Trevizan

Current methods for solving Stochastic Shortest Path Problems (SSPs) find states' costs-to-go by applying Bellman backups, where state-of-the-art methods employ heuristics to select states to back up and prune.

Learning Domain-Independent Heuristics for Grounded and Lifted Planning

no code implementations18 Dec 2023 Dillon Z. Chen, Sylvie Thiébaux, Felipe Trevizan

We present three novel graph representations of planning tasks suitable for learning domain-independent heuristics using Graph Neural Networks (GNNs) to guide search.

Heuristic Search for Multi-Objective Probabilistic Planning

no code implementations25 Mar 2023 Dillon Chen, Felipe Trevizan, Sylvie Thiébaux

Heuristic search is a powerful approach that has successfully been applied to a broad class of planning problems, including classical planning, multi-objective planning, and probabilistic planning modelled as a stochastic shortest path (SSP) problem.

Learning Domain-Independent Planning Heuristics with Hypergraph Networks

no code implementations29 Nov 2019 William Shen, Felipe Trevizan, Sylvie Thiébaux

We present the first approach capable of learning domain-independent planning heuristics entirely from scratch.

ASNets: Deep Learning for Generalised Planning

1 code implementation4 Aug 2019 Sam Toyer, Felipe Trevizan, Sylvie Thiébaux, Lexing Xie

In this paper, we discuss the learning of generalised policies for probabilistic and classical planning problems using Action Schema Networks (ASNets).

Action Schema Networks: Generalised Policies with Deep Learning

1 code implementation13 Sep 2017 Sam Toyer, Felipe Trevizan, Sylvie Thiébaux, Lexing Xie

In this paper, we introduce the Action Schema Network (ASNet): a neural network architecture for learning generalised policies for probabilistic planning problems.

Tableaux for Policy Synthesis for MDPs with PCTL* Constraints

no code implementations30 Jun 2017 Peter Baumgartner, Sylvie Thiébaux, Felipe Trevizan

Policy synthesis addresses the problem of how to control or limit the decisions an agent makes so that a given specification is met.

Trajectory-Based Short-Sighted Probabilistic Planning

no code implementations NeurIPS 2012 Felipe Trevizan, Manuela Veloso

In order to compute a solution for a probabilistic planning problem, planners need to manage the uncertainty associated with the different paths from the initial state to a goal state.
