FANOK: Knockoffs in Linear Time

1 code implementation15 Jun 2020 Armin Askari, Quentin Rebjock, Alexandre d'Aspremont, Laurent El Ghaoui

We describe a series of algorithms that efficiently implement Gaussian model-X knockoffs to control the false discovery rate on large scale feature selection problems.

Implicit Deep Learning

no code implementations17 Aug 2019 Laurent El Ghaoui, Fangda Gu, Bertrand Travacca, Armin Askari, Alicia Y. Tsai

Implicit deep learning prediction rules generalize the recursive rules of feedforward neural networks.

Naive Feature Selection: Sparsity in Naive Bayes

no code implementations23 May 2019 Armin Askari, Alexandre d'Aspremont, Laurent El Ghaoui

We propose a sparse version of naive Bayes, which can be used for feature selection.

Fenchel Lifted Networks: A Lagrange Relaxation of Neural Network Training

1 code implementation20 Nov 2018 Fangda Gu, Armin Askari, Laurent El Ghaoui

In this paper, we introduce a new class of lifted models, Fenchel lifted networks, that enjoy the same benefits as previous lifted models, without suffering a degradation in performance over classical networks.

Greedy Frank-Wolfe Algorithm for Exemplar Selection

2 code implementations6 Nov 2018 Gary Cheng, Armin Askari, Kannan Ramchandran, Laurent El Ghaoui

In this paper, we consider the problem of selecting representatives from a data set for arbitrary supervised/unsupervised learning tasks.

Kernel-based Outlier Detection using the Inverse Christoffel Function

no code implementations18 Jun 2018 Armin Askari, Forest Yang, Laurent El Ghaoui

Outlier detection methods have become increasingly relevant in recent years due to increased security concerns and because of its vast application to different fields.

Lifted Neural Networks

no code implementations3 May 2018 Armin Askari, Geoffrey Negiar, Rajiv Sambharya, Laurent El Ghaoui

We describe a novel family of models of multi- layer feedforward neural networks in which the activation functions are encoded via penalties in the training problem.
