Adjusting the adjusted Rand Index -- A multinomial story

Martina Sundqvist, Julien Chiquet, Guillem Rigaill

The Adjusted Rand Index () is arguably one of the most popular measures for cluster comparison. The adjustment of the is based on a hypergeometric distribution assumptio…

Fast Detection of Block Boundaries in Block Wise Constant Matrices: An Application to HiC data

Vincent Brault, Julien Chiquet, Céline Lévy-Leduc

We propose a novel approach for estimating the location of block boundaries (change-points) in a random matrix consisting of a block wise constant matrix observed in white noise. O…
