Beyond the Manifold Hypothesis: Hybrid Spectral Parameterizations for Flow Matching

Ségolène Martin, Anne Gagneux, Quentin Bertrand +2

Flow matching and diffusion can be trained to predict different quantities, most commonly the data , the source noise , or the velocity~. Although theoretically equiva…

On the Closed-Form of Flow Matching: Generalization Does Not Arise from Target Stochasticity

Quentin Bertrand, Anne Gagneux, Mathurin Massias +1

Modern deep generative models can now produce high-quality synthetic samples that are often indistinguishable from real training data. A growing body of research aims to understand…

Beyond L1: Faster and Better Sparse Models with skglm

Quentin Bertrand, Quentin Klopfenstein, Pierre-Antoine Bannier +2

We propose a new fast algorithm to estimate any sparse generalized linear model with convex or non-convex separable penalties. Our algorithm is able to solve problems with millions…

Graph-Theoretic Models of Resource Distribution for Cyber-Physical Systems of Disaster-Affected Regions

Kenneth Johnson, Samaneh Madanian, Roopak Sinha

We propose a tool-supported framework to reason about requirements constraining resource distributions and devise strategies for routing essential services in a disaster-affected r…

Implicit differentiation for fast hyperparameter selection in non-smooth convex learning

Quentin Bertrand, Quentin Klopfenstein, Mathurin Massias +4

Finding the optimal hyperparameters of a model can be cast as a bilevel optimization problem, typically solved using zero-order techniques. In this work we study first-order method…

Anderson acceleration of coordinate descent

Quentin Bertrand, Mathurin Massias

Acceleration of first order methods is mainly obtained via inertial techniques à la Nesterov, or via nonlinear extrapolation. The latter has known a recent surge of interest, with…
