VISER: Visual Self-Regularization

no code implementations7 Feb 2018 Hamid Izadinia, Pierre Garrigues

In this work, we propose the use of large set of unlabeled images as a source of regularization data for learning robust visual representation.

The New Modality: Emoji Challenges in Prediction, Anticipation, and Retrieval

no code implementations30 Jan 2018 Spencer Cappallo, Stacey Svetlichnaya, Pierre Garrigues, Thomas Mensink, Cees G. M. Snoek

Over the past decade, emoji have emerged as a new and widespread form of digital communication, spanning diverse social networks and spoken languages.

Tag Prediction at Flickr: a View from the Darkroom

no code implementations6 Dec 2016 Kofi Boakye, Sachin Farfade, Hamid Izadinia, Yannis Kalantidis, Pierre Garrigues

Our results demonstrate that, for real-world datasets, training exclusively with this noisy data yields performance on par with the standard paradigm of first pre-training on clean data and then fine-tuning.

Group Sparse Coding with a Laplacian Scale Mixture Prior

no code implementations NeurIPS 2010 Pierre Garrigues, Bruno A. Olshausen

We show that, due to the conjugacy of the Gamma prior, it is possible to derive efficient inference procedures for both the coefficients and the scale parameter.

An Homotopy Algorithm for the Lasso with Online Observations

no code implementations NeurIPS 2008 Pierre Garrigues, Laurent E. Ghaoui

It has been shown that the problem of $\ell_1$-penalized least-square regression commonly referred to as the Lasso or Basis Pursuit DeNoising leads to solutions that are sparse and therefore achieves model selection.

Learning Horizontal Connections in a Sparse Coding Model of Natural Images

no code implementations NeurIPS 2007 Pierre Garrigues, Bruno A. Olshausen

It has been shown that adapting a dictionary of basis functions to the statistics of natural images so as to maximize sparsity in the coefficients results in a set of dictionary elements whose spatial properties resemble those of V1 (primary visual cortex) receptive fields.
