On the potential benefits of entropic regularization for smoothing Wasserstein estimators

no code implementations13 Oct 2022 Jérémie Bigot, Paul Freulon, Boris P. Hejblum, Arthur Leclaire

This paper is focused on the study of entropic regularization in optimal transport as a smoothing method for Wasserstein estimators, through the prism of the classical tradeoff between approximation and estimation errors in statistics.

Sequential Dirichlet Process Mixtures of Multivariate Skew t-distributions for Model-based Clustering of Flow Cytometry Data

2 code implementations14 Feb 2017 Boris P. Hejblum, Chariff Alkhassim, Raphael Gottardo, François Caron, Rodolphe Thiébaut

DPM models directly estimate the number of cell populations from the data, avoiding model selection issues, and skew $t$-distributions provides robustness to outliers and non-elliptical shape of cell populations.

Variance component score test for time-course gene set analysis of longitudinal RNA-seq data

1 code implementation8 May 2016 Denis Agniel, Boris P. Hejblum

As gene expression measurement technology is shifting from microarrays to sequencing, the statistical tools available for their analysis must be adapted since RNA-seq data are measured as counts.
