A randomized algorithm to solve reduced rank operator regression

1 code implementation28 Dec 2023 Giacomo Turri, Vladimir Kostic, Pietro Novelli, Massimiliano Pontil

We present and analyze an algorithm designed for addressing vector-valued regression problems involving possibly infinite-dimensional input and output spaces.

Consistent Long-Term Forecasting of Ergodic Dynamical Systems

no code implementations20 Dec 2023 Prune Inzerilli, Vladimir Kostic, Karim Lounici, Pietro Novelli, Massimiliano Pontil

We study the evolution of distributions under the action of an ergodic dynamical system, which may be stochastic in nature.

Dynamics Harmonic Analysis of Robotic Systems: Application in Data-Driven Koopman Modelling

2 code implementations12 Dec 2023 Daniel Ordoñez-Apraez, Vladimir Kostic, Giulio Turrisi, Pietro Novelli, Carlos Mastalli, Claudio Semini, Massimiliano Pontil

We introduce the use of harmonic analysis to decompose the state space of symmetric robotic systems into orthogonal isotypic subspaces.

Convergence of Batch Greenkhorn for Regularized Multimarginal Optimal Transport

no code implementations1 Dec 2021 Vladimir Kostic, Saverio Salzo, Massimilano Pontil

In this work we propose a batch version of the Greenkhorn algorithm for multimarginal regularized optimal transport problems.

The method of Bregman projections in deterministic and stochastic convex feasibility problems

no code implementations5 Jan 2021 Vladimir Kostic, Saverio Salzo

We analyze in depth the case of affine feasibility problems showing that the iterates generated by the proposed methods converge Q-linearly and providing also explicit global and local rates of convergence.
