Aortic valve stenosis (AS) is a chronic progressive disease whose prevalence is likely to triple in the coming decades in North America, with a consequent impact on health and the economy. However, efficient drug therapies for this disease are not available. The need for appropriate medication is therefore driving the exploration of the various...

The GemClus package provides simple tools to perform discriminative clustering using the generalised mutual information (GEMINI). The package was written to be a scikit-learn compatible extension.GEMINI is a clustering-dedicated function derived from information theory that allows to do clustering without hypotheses on the data distributions....

Trees are convenient models for obtaining explainable predictions on relatively small datasets. Although there are many proposals for the end-to-end construction of such trees in supervised learning, learning a tree end-to-end for clustering without labels remains an open challenge. As most works focus on interpreting with trees the result of...

Feature selection in clustering is a hard task which involves simultaneously the discovery of relevant clusters as well as relevant variables with respect to these clusters. While feature selection algorithms are often model-based through optimised model selection or strong assumptions on p(x x x), we introduce a discriminative clustering model...

In the last decade, recent successes in deep clustering majorly involved the Mutual Information (MI) as an unsupervised objective for training neural networks with increasing regularisations. While the quality of the regularisations have been largely discussed for improvements, little attention has been dedicated to the relevance of MI as a...
