Cluster-Based Normalization Layer for Neural Networks

no code implementations25 Mar 2024 Bilal Faye, Hanane Azzag, Mustapha Lebbah

This paper introduces Cluster-Based Normalization (CB-Norm) in two variants - Supervised Cluster-Based Normalization (SCB-Norm) and Unsupervised Cluster-Based Normalization (UCB-Norm) - proposing a groundbreaking one-step normalization approach.

Context-Based Multimodal Fusion

no code implementations7 Mar 2024 Bilal Faye, Hanane Azzag, Mustapha Lebbah, Djamel Bouchaffra

Additionally, the network learns to differentiate embeddings of different modalities through fusion with context and aligns data distributions using a contrastive approach for self-supervised learning.

Transformer-based conditional generative adversarial network for multivariate time series generation

no code implementations5 Oct 2022 Abdellah Madane, Mohamed-djallel Dilmi, Florent Forest, Hanane Azzag, Mustapha Lebbah, Jerome Lacaille

One of its limitations is that it may generate a random multivariate time series; it may fail to generate samples in the presence of multiple sub-components within an overall distribution.

A Survey and Implementation of Performance Metrics for Self-Organized Maps

1 code implementation11 Nov 2020 Florent Forest, Mustapha Lebbah, Hanane Azzag, Jérôme Lacaille

Quantitative evaluation of self-organizing maps (SOM) is a subset of clustering validation, which is a challenging problem as such.

Conditional Latent Block Model: a Multivariate Time Series Clustering Approach for Autonomous Driving Validation

1 code implementation3 Aug 2020 Etienne Goffinet, Anthony Coutant, Mustapha Lebbah, Hanane Azzag, Loïc Giraldi

The FunCLBM model extends the recently proposed Functional Latent Block Model and allows to create a dependency structure between row and column clusters.

Selecting the Number of Clusters $K$ with a Stability Trade-off: an Internal Validation Criterion

1 code implementation15 Jun 2020 Alex Mourer, Florent Forest, Mustapha Lebbah, Hanane Azzag, Jérôme Lacaille

In this perspective, clustering stability has emerged as a natural and model-agnostic principle: an algorithm should find stable structures in the data.

Algorithms for an Efficient Tensor Biclustering

no code implementations10 Mar 2019 Andriantsiory Dina Faneva, Mustapha Lebbah, Hanane Azzag, Gaël Beck

Consider a data set collected by (individuals-features) pairs in different times.

A Distributed and Approximated Nearest Neighbors Algorithm for an Efficient Large Scale Mean Shift Clustering

no code implementations11 Feb 2019 Gaël Beck, Tarn Duong, Mustapha Lebbah, Hanane Azzag, Christophe Cérin

Mean Shift clustering is a generalization of the k-means clustering which computes arbitrarily shaped clusters as defined as the basins of attraction to the local modes created by the density gradient ascent paths.
