Feature Learning beyond the Lazy-Rich Dichotomy: Insights from Representational Geometry

ICML 2025spotlight

Integrating task-relevant information into neural representations is a fundamental ability of both biological and artificial intelligence systems. Recent theories have categorized learning into two regimes: the rich regime, where neural networks actively learn task-relevant features, and the lazy r…

Lightweight Adapter Tuning for Multilingual Speech Translation

ACL 2021short

Adapter modules were recently introduced as an efficient alternative to fine-tuning in NLP. Adapter tuning consists in freezing pre-trained parameters of a model and injecting lightweight modules between layers, resulting in the addition of only a small number of task-specific trainable parameters.…

Neural Population Geometry Reveals the Role of Stochasticity in Robust Perception

NeurIPS 2021poster

Adversarial examples are often cited by neuroscientists and machine learning researchers as an example of how computational models diverge from biological sensory systems. Recent work has proposed adding biologically-inspired components to visual neural networks as a way to improve their adversarial…

Task Agnostic and Task Specific Self-Supervised Learning from Speech with LeBenchmark

NeurIPS 2021poster

Self-Supervised Learning (SSL) has yielded remarkable improvements in many different domains including computer vision, natural language processing and speech processing by leveraging large amounts of unlabeled data. In the specific context of speech, however, and despite promising results, there ex…

Dual-decoder Transformer for Joint Automatic Speech Recognition and Multilingual Speech Translation

COLING 2020main

We introduce dual-decoder Transformer, a new model architecture that jointly performs automatic speech recognition (ASR) and multilingual speech translation (ST). Our models are based on the original Transformer architecture (Vaswani et al., 2017) but consist of two decoders, each responsible for on…

Emergence of Separable Manifolds in Deep Language Representations

ICML 2020poster

Deep neural networks (DNNs) have shown much empirical success in solving perceptual tasks across various cognitive modalities. While they are only loosely inspired by the biological brain, recent studies report considerable similarities between representations extracted from task-optimized DNNs and…
