Generalized Functional Pruning Optimal Partitioning (GFPOP) for Constrained Changepoint Detection in Genomic Data

4 code implementations29 Sep 2018 Toby Dylan Hocking, Guillem Rigaill, Paul Fearnhead, Guillaume Bourque

We describe a new algorithm and R package for peak detection in genomic data sets using constrained changepoint algorithms.

A log-linear time algorithm for constrained changepoint detection

7 code implementations9 Mar 2017 Toby Dylan Hocking, Guillem Rigaill, Paul Fearnhead, Guillaume Bourque

This leads to a new algorithm which can solve problems with arbitrary affine constraints on adjacent segment means, and which has empirical time complexity that is log-linear in the amount of data.

PeakSegJoint: fast supervised peak detection via joint segmentation of multiple count data samples

1 code implementation3 Jun 2015 Toby Dylan Hocking, Guillaume Bourque

To select the number of peaks in the segmentation, we propose a supervised penalty learning model.
