Multivariate Online Linear Regression for Hierarchical Forecasting

no code implementations22 Feb 2024 Massil Hihat, Guillaume Garrigos, Adeline Fermanian, Simon Bussy

In this paper, we consider a deterministic online linear regression model where we allow the responses to be multivariate.

Binacox: automatic cut-point detection in high-dimensional Cox model with applications in genetics

1 code implementation25 Jul 2018 Simon Bussy, Mokhtar Z. Alaya, Anne-Sophie Jannot, Agathe Guilloux

We introduce the binacox, a prognostic method to deal with the problem of detecting multiple cut-points per features in a multivariate setting where a large number of continuous features are available.

Binarsity: a penalization for one-hot encoded features in linear supervised learning

no code implementations24 Mar 2017 Mokhtar Z. Alaya, Simon Bussy, Stéphane Gaïffas, Agathe Guilloux

In each group of binary features coming from the one-hot encoding of a single raw continuous feature, this penalization uses total-variation regularization together with an extra linear constraint.

C-mix: a high dimensional mixture model for censored durations, with applications to genetic data

1 code implementation24 Oct 2016 Simon Bussy, Agathe Guilloux, Stéphane Gaïffas, Anne-Sophie Jannot

We introduce a mixture model for censored durations (C-mix), and develop maximum likelihood inference for the joint estimation of the time distributions and latent regression parameters of the model.
