MLXP: A framework for conducting replicable Machine Learning eXperiments in Python

1 code implementation21 Feb 2024 Michael Arbel, Alexandre Zouaoui

Replicability in machine learning (ML) research is increasingly concerning due to the utilization of complex non-deterministic algorithms and the dependence on numerous hyper-parameter choices, such as model architecture and training datasets.

Fast Semi-supervised Unmixing using Non-convex Optimization

1 code implementation23 Jan 2024 Behnood Rasti, Alexandre Zouaoui, Julien Mairal, Jocelyn Chanussot

Our experimental results validate that enforcing the convexity constraint outperforms the sparsity prior for the endmember library.

SUnAA: Sparse Unmixing using Archetypal Analysis

1 code implementation9 Aug 2023 Behnood Rasti, Alexandre Zouaoui, Julien Mairal, Jocelyn Chanussot

Unlike most conventional sparse unmixing methods, here the minimization problem is non-convex.

Entropic Descent Archetypal Analysis for Blind Hyperspectral Unmixing

1 code implementation22 Sep 2022 Alexandre Zouaoui, Gedeon Muhawenayo, Behnood Rasti, Jocelyn Chanussot, Julien Mairal

In this paper, we introduce a new algorithm based on archetypal analysis for blind hyperspectral unmixing, assuming linear mixing of endmembers.

Hyperspectral Unmixing Model Selection

A Trainable Spectral-Spatial Sparse Coding Model for Hyperspectral Image Restoration

2 code implementations NeurIPS 2021 Théo Bodrito, Alexandre Zouaoui, Jocelyn Chanussot, Julien Mairal

Hyperspectral imaging offers new perspectives for diverse applications, ranging from the monitoring of the environment using airborne or satellite remote sensing, precision farming, food safety, planetary exploration, or astrophysics.
