DP-Net: Learning Discriminative Parts for image recognition

no code implementations23 Apr 2024 Ronan Sicre, Hanwei Zhang, Julien Dejasmin, Chiheb Daaloul, Stéphane Ayache, Thierry Artières

This paper presents Discriminative Part Network (DP-Net), a deep architecture with strong interpretation capabilities, which exploits a pretrained Convolutional Neural Network (CNN) combined with a part-based recognition module.

Implicit Regularization in Deep Tensor Factorization

no code implementations4 May 2021 Paolo Milanesi, Hachem Kadri, Stéphane Ayache, Thierry Artières

Attempts of studying implicit regularization associated to gradient descent (GD) have identified matrix completion as a suitable test-bed.

Matrix Completion

Mapping individual differences in cortical architecture using multi-view representation learning

no code implementations1 Apr 2020 Akrem Sellami, François-Xavier Dupé, Bastien Cagna, Hachem Kadri, Stéphane Ayache, Thierry Artières, Sylvain Takerkart

In neuroscience, understanding inter-individual differences has recently emerged as a major challenge, for which functional magnetic resonance imaging (fMRI) has proven invaluable.

Deep Networks with Adaptive Nyström Approximation

no code implementations29 Nov 2019 Luc Giffon, Stéphane Ayache, Thierry Artières, Hachem Kadri

Recent work has focused on combining kernel methods and deep learning to exploit the best of the two approaches.

Unsupervised Object Segmentation by Redrawing

1 code implementation NeurIPS 2019 Mickaël Chen, Thierry Artières, Ludovic Denoyer

Object segmentation is a crucial problem that is usually solved by using supervised learning approaches over very large datasets composed of both images and corresponding object masks.

Multi-View Data Generation Without View Supervision

1 code implementation ICLR 2018 Mickaël Chen, Ludovic Denoyer, Thierry Artières

We assume that the distribution of the data is driven by two independent latent factors: the content, which represents the intrinsic features of an object, and the view, which stands for the settings of a particular observation of that object.

Sequential Cost-Sensitive Feature Acquisition

no code implementations13 Jul 2016 Gabriella Contardo, Ludovic Denoyer, Thierry Artières

We propose a reinforcement learning based approach to tackle the cost-sensitive learning problem where each input feature has a specific cost.
