Fast and Consistent Algorithm for the Latent Block Model
Vincent Brault, Antoine Channarond
The latent block model is used to simultaneously rank the rows and columns of a matrix to reveal a block structure. The algorithms used for estimation are often time consuming. How…
Nonparametric homogeneity tests and multiple change-point estimation for analyzing large Hi-C data matrices
Vincent Brault, Sarah Ouadah, Laure Sansonnet +1
We propose a novel nonparametric approach for estimating the location of block boundaries (change-points) of non-overlapping blocks in a random symmetric matrix which consists of r…
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…
