Deep Recurrent Encoder: A scalable end-to-end network to model brain signals

Omar Chehab, Alexandre Defossez, Jean-Christophe Loiseau +2

Understanding how the brain responds to sensory inputs is challenging: brain recordings are partial, noisy, and high dimensional; they vary across sessions and subjects and they ca…

Real Time Speech Enhancement in the Waveform Domain

Alexandre Defossez, Gabriel Synnaeve, Yossi Adi

We present a causal speech enhancement model working on the raw waveform that runs in real-time on a laptop CPU. The proposed model is based on an encoder-decoder architecture with…

Demucs: Deep Extractor for Music Sources with extra unlabeled data remixed

Alexandre Défossez, Nicolas Usunier, Léon Bottou +1

We study the problem of source separation for music using deep learning with four known sources: drums, bass, vocals and other accompaniments. State-of-the-art approaches predict s…

SING: Symbol-to-Instrument Neural Generator

Alexandre Défossez, Neil Zeghidour, Nicolas Usunier +2

Recent progress in deep learning for audio synthesis opens the way to models that directly produce the waveform, shifting away from the traditional paradigm of relying on vocoders…

AdaBatch: Efficient Gradient Aggregation Rules for Sequential and Parallel Stochastic Gradient Methods

Alexandre Défossez, Francis Bach

We study a new aggregation operator for gradients coming from a mini-batch for stochastic gradient (SG) methods that allows a significant speed-up in the case of sparse optimizatio…

Constant Step Size Least-Mean-Square: Bias-Variance Trade-offs and Optimal Sampling Distributions

Alexandre Défossez, Francis Bach

We consider the least-squares regression problem and provide a detailed asymptotic analysis of the performance of averaged constant-step-size stochastic gradient descent (a.k.a. le…
