Weight Identification Through Global Optimization in a New Hysteretic Neural Network Model

ICASSP 2021accepted

Unlike their biological counterparts, simple artificial neural networks are unable to retain information from their past state to influence their behavior. In this contribution, we propose to consider new nonlinear activation functions, whose outputs depend both from the current and past inputs thro…

Catseyes: Categorizing Seismic Structures with Tessellated Scattering Wavelet Networks

ICASSP 2018accepted

As field seismic data sizes are dramatically increasing toward exabytes, automating the labeling of “structural monads” - corresponding to geological patterns and yielding subsurface interpretation - in a huge amount of available information would drastically reduce interpretation time. Since custom…

Fast convex optimization for connectivity enforcement in gene regulatory network inference

ICASSP 2015accepted

With the advent of microarrays, arose the need to analyze gene expression data. Tools for building gene regulation networks are indeed of high interest for regulatory relationship sketching and gene interaction prediction. Given all pairwise gene regulation information available, we propose to deter…
