Pruning Sparse Tensor Neural Networks Enables Deep Learning for 3D Ultrasound Localization Microscopy

1 code implementation14 Feb 2024 Brice Rauby, Paul Xing, Jonathan Porée, Maxime Gasse, Jean Provost

We show that Sparse Tensor Neural Networks in 3D ULM allow for the same benefits as dense deep learning based method in 2D ULM i. e. the use of higher concentration in silico and reduced acquisition time.

A Deep Learning Framework for Spatiotemporal Ultrasound Localization Microscopy

no code implementations12 Oct 2023 Léo Milecki, Jonathan Porée, Hatim Belgharbi, Chloé Bourquin, Rafat Damseh, Patrick Delafontaine-Martel, Frédéric Lesage, Maxime Gasse, Jean Provost

Ultrasound data sets from multiple microbubbles flowing through the microvascular network were simulated and used as ground truth to train the 3D CNN to track microbubbles.

Lookback for Learning to Branch

no code implementations30 Jun 2022 Prateek Gupta, Elias B. Khalil, Didier Chetélat, Maxime Gasse, Yoshua Bengio, Andrea Lodi, M. Pawan Kumar

Given that B&B results in a tree of sub-MILPs, we ask (a) whether there are strong dependencies exhibited by the target heuristic among the neighboring nodes of the B&B tree, and (b) if so, whether we can incorporate them in our training procedure.

Learning to branch with Tree MDPs

1 code implementation23 May 2022 Lara Scavuzzo, Feng Yang Chen, Didier Chételat, Maxime Gasse, Andrea Lodi, Neil Yorke-Smith, Karen Aardal

State-of-the-art Mixed Integer Linear Program (MILP) solvers combine systematic tree search with a plethora of hard-coded heuristics, such as the branching rule.

Causal Reinforcement Learning using Observational and Interventional Data

1 code implementation28 Jun 2021 Maxime Gasse, Damien Grasset, Guillaume Gaudron, Pierre-Yves Oudeyer

We then ask the following questions: can the online and offline experiences be safely combined for learning a causal model ?

Ecole: A Library for Learning Inside MILP Solvers

1 code implementation6 Apr 2021 Antoine Prouvost, Justin Dumouchelle, Maxime Gasse, Didier Chételat, Andrea Lodi

In this paper we describe Ecole (Extensible Combinatorial Optimization Learning Environments), a library to facilitate integration of machine learning in combinatorial optimization solvers.

Hybrid Models for Learning to Branch

1 code implementation NeurIPS 2020 Prateek Gupta, Maxime Gasse, Elias B. Khalil, M. Pawan Kumar, Andrea Lodi, Yoshua Bengio

First, in a more realistic setting where only a CPU is available, is the GNN model still competitive?

F-measure Maximization in Multi-Label Classification with Conditionally Independent Label Subsets

1 code implementation26 Apr 2016 Maxime Gasse, Alex Aussem

In this work, we show that the number of parameters can be reduced further to $m^2/n$, in the best case, assuming the label set can be partitioned into $n$ conditionally independent subsets.

A hybrid algorithm for Bayesian network structure learning with application to multi-label learning

1 code implementation18 Jun 2015 Maxime Gasse, Alex Aussem, Haytham Elghazel

Our extensive experiments show that H2PC outperforms MMHC in terms of goodness of fit to new data and quality of the network structure with respect to the true dependence structure of the data.

An Experimental Comparison of Hybrid Algorithms for Bayesian Network Structure Learning

no code implementations19 May 2015 Maxime Gasse, Alex Aussem, Haytham Elghazel

We present a novel hybrid algorithm for Bayesian network structure learning, called Hybrid HPC (H2PC).
