Training Integrable Parameterizations of Deep Neural Networks in the Infinite-Width Limit

1 code implementation29 Oct 2021 Karl Hajjar, Lénaïc Chizat, Christophe Giraud

For two-layer neural networks, it has been understood via these asymptotics that the nature of the trained model radically changes depending on the scale of the initial random weights, ranging from a kernel regime (for large initial variance) to a feature learning regime (for small initial variance).

SizeFlags: Reducing Size and Fit Related Returns in Fashion E-Commerce

no code implementations7 Jun 2021 Andrea Nestler, Nour Karessli, Karl Hajjar, Rodrigo Weffer, Reza Shirvany

Size and fit related returns severely impact 1. the customers experience and their dissatisfaction with online shopping, 2. the environment through an increased carbon footprint, and 3. the profitability of online fashion platforms.

Ranked Reward: Enabling Self-Play Reinforcement Learning for Combinatorial Optimization

2 code implementations4 Jul 2018 Alexandre Laterre, Yunguan Fu, Mohamed Khalil Jabri, Alain-Sam Cohen, David Kas, Karl Hajjar, Torbjorn S. Dahl, Amine Kerkeni, Karim Beguir

Results from applying the R2 algorithm to instances of a two-dimensional and three-dimensional bin packing problems show that it outperforms generic Monte Carlo tree search, heuristic algorithms and integer programming solvers.
