Shieldstral

Antonia Calvi, Avinash Sooriyarachchi, Giada Pistilli +273

We introduce Shieldstral, a 3B-parameter policy-adaptive multimodal safety classifier that matches or outperforms models nearly 7 its size on text safety benchmarks and set…

REPA-G: Test-Time Conditioning with Representation-Aligned Visual Features

Nicolas Sereyjol-Garros, Ellington Kirby, Victor Letzelter +2

While representation alignment with self-supervised models has been shown to improve diffusion model training, its potential for enhancing inference-time conditioning remains large…

Multiple Choice Learning of Low-Rank Adapters for Language Modeling

Victor Letzelter, Hugo Malard, Mathieu Fontaine +4

We propose LoRA-MCL, a training scheme that extends next-token prediction in language models with a method designed to decode diverse, plausible sentence continuations at inference…

Winner-takes-all for Multivariate Probabilistic Time Series Forecasting

Adrien Cortés, Rémi Rehm, Victor Letzelter

We introduce TimeMCL, a method leveraging the Multiple Choice Learning (MCL) paradigm to forecast multiple plausible time series futures. Our approach employs a neural network with…

Annealed Winner-Takes-All for Motion Forecasting

Yihong Xu, Victor Letzelter, Mickaël Chen +2

In autonomous driving, motion prediction aims at forecasting the future trajectories of nearby agents, helping the ego vehicle to anticipate behaviors and drive safely. A key chall…

Annealed Multiple Choice Learning: Overcoming limitations of Winner-takes-all with annealing

David Perera, Victor Letzelter, Théo Mariotte +4

We introduce Annealed Multiple Choice Learning (aMCL) which combines simulated annealing with MCL. MCL is a learning framework handling ambiguous tasks by predicting a small set of…

Winner-takes-all learners are geometry-aware conditional density estimators

Victor Letzelter, David Perera, Cédric Rommel +4

Winner-takes-all training is a simple learning paradigm, which handles ambiguous tasks by predicting a set of plausible hypotheses. Recently, a connection was established between W…

ManiPose: Manifold-Constrained Multi-Hypothesis 3D Human Pose Estimation

Cédric Rommel, Victor Letzelter, Nermin Samet +4

We propose ManiPose, a manifold-constrained multi-hypothesis model for human-pose 2D-to-3D lifting. We provide theoretical and empirical evidence that, due to the depth ambiguity i…

Resilient Multiple Choice Learning: A learned scoring scheme with application to audio scene analysis

Victor Letzelter, Mathieu Fontaine, Mickaël Chen +3

We introduce Resilient Multiple Choice Learning (rMCL), an extension of the MCL approach for conditional distribution estimation in regression settings where multiple targets may b…
