Combining Monte Carlo Tree Search and Heuristic Search for Weighted Vertex Coloring

1 code implementation24 Apr 2023 Cyril Grelier, Olivier Goudet, Jin-Kao Hao

This work investigates the Monte Carlo Tree Search (MCTS) method combined with dedicated heuristics for solving the Weighted Vertex Coloring Problem.

On Monte Carlo Tree Search for Weighted Vertex Coloring

1 code implementation3 Feb 2022 Cyril Grelier, Olivier Goudet, Jin-Kao Hao

This work presents the first study of using the popular Monte Carlo Tree Search (MCTS) method combined with dedicated heuristics for solving the Weighted Vertex Coloring Problem.

A deep learning guided memetic framework for graph coloring problems

no code implementations13 Sep 2021 Olivier Goudet, Cyril Grelier, Jin-Kao Hao

Given an undirected graph $G=(V, E)$ with a set of vertices $V$ and a set of edges $E$, a graph coloring problem involves finding a partition of the vertices into different independent sets.

A massively parallel evolutionary algorithm for the partial Latin square extension problem

no code implementations18 Mar 2021 Olivier Goudet, Jin-Kao Hao

The partial Latin square extension problem is to fill as many as possible empty cells of a partially filled Latin square.

Survival Estimation for Missing not at Random Censoring Indicators based on Copula Models

1 code implementation3 Sep 2020 Mikael Escobar-Bach, Olivier Goudet

In the presence of right-censored data with covariates, the conditional Kaplan-Meier estimator (also known as the Beran estimator) consistently estimates the conditional survival function of the random follow-up for the event of interest.

Population-based Gradient Descent Weight Learning for Graph Coloring Problems

1 code implementation5 Sep 2019 Olivier Goudet, Béatrice Duval, Jin-Kao Hao

Unlike existing methods for graph coloring that are specific to the considered problem, the presented work targets a generic objective by introducing a unified method that can be applied to different graph coloring problems.

Causal Discovery Toolbox: Uncover causal relationships in Python

3 code implementations6 Mar 2019 Diviyan Kalainathan, Olivier Goudet

This paper presents a new open source Python framework for causal discovery from observational data and domain background knowledge, aimed at causal graph and causal mechanism modeling.

Causal Discovery

Causal Generative Neural Networks

1 code implementation ICLR 2018 Olivier Goudet, Diviyan Kalainathan, Philippe Caillou, Isabelle Guyon, David Lopez-Paz, Michèle Sebag

We present Causal Generative Neural Networks (CGNNs) to learn functional causal models from observational data.

Causal Discovery

Learning Functional Causal Models with Generative Neural Networks

2 code implementations15 Sep 2017 Olivier Goudet, Diviyan Kalainathan, Philippe Caillou, Isabelle Guyon, David Lopez-Paz, Michèle Sebag

We introduce a new approach to functional causal modeling from observational data, called Causal Generative Neural Networks (CGNN).
