QGen: On the Ability to Generalize in Quantization Aware Training

no code implementations17 Apr 2024 MohammadHossein AskariHemmat, Ahmadreza Jeddi, Reyhane Askari Hemmat, Ivan Lazarevich, Alexander Hoffman, Sudhakar Sah, Ehsan Saboori, Yvon Savaria, Jean-Pierre David

In this work, we investigate the generalization properties of quantized neural networks, a characteristic that has received little attention despite its implications on model performance.

Feedback-guided Data Synthesis for Imbalanced Classification

1 code implementation29 Sep 2023 Reyhane Askari Hemmat, Mohammad Pezeshki, Florian Bordes, Michal Drozdzal, Adriana Romero-Soriano

In this work, we introduce a framework for augmenting static datasets with useful synthetic samples, which leverages one-shot feedback from the classifier to drive the sampling of the generative model.

QReg: On Regularization Effects of Quantization

no code implementations24 Jun 2022 MohammadHossein AskariHemmat, Reyhane Askari Hemmat, Alex Hoffman, Ivan Lazarevich, Ehsan Saboori, Olivier Mastropietro, Yvon Savaria, Jean-Pierre David

To confirm our analytical study, we performed an extensive list of experiments summarized in this paper in which we show that the regularization effects of quantization can be seen in various vision tasks and models, over various datasets.
