NoisET: Noise learning and Expansion detection of T-cell receptors

1 code implementation6 Feb 2021 Meriem Bensouda Koraichi, Maximilian Puelma Touzel, Andrea Mazzolini, Thierry Mora, Aleksandra M. Walczak

High-throughput sequencing of T- and B-cell receptors makes it possible to track immune repertoires across time, in different tissues, in acute and chronic diseases and in healthy individuals.

On Lyapunov Exponents for RNNs: Understanding Information Propagation Using Dynamical Systems Tools

no code implementations25 Jun 2020 Ryan Vogt, Maximilian Puelma Touzel, Eli Shlizerman, Guillaume Lajoie

Recurrent neural networks (RNNs) have been successfully applied to a variety of problems involving sequential data, but their optimization is sensitive to parameter initialization, architecture, and optimizer hyperparameters.

Inferring the immune response from repertoire sequencing

1 code implementation17 Dec 2019 Maximilian Puelma Touzel, Aleksandra M. Walczak, Thierry Mora

High-throughput sequencing of B- and T-cell receptors makes it possible to track immune repertoires across time, in different tissues, and in acute and chronic diseases or in healthy individuals.

Non-normal Recurrent Neural Network (nnRNN): learning long time dependencies while improving expressivity with transient dynamics

1 code implementation NeurIPS 2019 Giancarlo Kerg, Kyle Goyette, Maximilian Puelma Touzel, Gauthier Gidel, Eugene Vorontsov, Yoshua Bengio, Guillaume Lajoie

A recent strategy to circumvent the exploding and vanishing gradient problem in RNNs, and to allow the stable propagation of signals over long time scales, is to constrain recurrent connectivity matrices to be orthogonal or unitary.
