ENOT: Expectile Regularization for Fast and Accurate Training of Neural Optimal Transport

no code implementations6 Mar 2024 Nazar Buzun, Maksim Bobrin, Dmitry V. Dylov

We present a new extension for Neural Optimal Transport (NOT) training procedure, capable of accurately and efficiently estimating optimal transportation plan via specific regularisation on conjugate potentials.

Align Your Intents: Offline Imitation Learning via Optimal Transport

no code implementations20 Feb 2024 Maksim Bobrin, Nazar Buzun, Dmitrii Krylov, Dmitry V. Dylov

We report that AILOT outperforms state-of-the art offline imitation learning algorithms on D4RL benchmarks and improves the performance of other offline RL algorithms in the sparse-reward tasks.

Explain My Surprise: Learning Efficient Long-Term Memory by Predicting Uncertain Outcomes

1 code implementation27 Jul 2022 Artyom Sorokin, Nazar Buzun, Leonid Pugachev, Mikhail Burtsev

This requires to store prohibitively large intermediate data if a sequence consists of thousands or even millions elements, and as a result, makes learning of very long-term dependencies infeasible.

Data Augmentation with Manifold Barycenters

no code implementations2 Apr 2021 Iaroslav Bespalov, Nazar Buzun, Oleg Kachan, Dmitry V. Dylov

Oftentimes, these methods either fail to produce enough new data or expand the dataset beyond the original knowledge domain.

BRULÈ: Barycenter-Regularized Unsupervised Landmark Extraction

no code implementations20 Jun 2020 Iaroslav Bespalov, Nazar Buzun, Dmitry V. Dylov

Unsupervised retrieval of image features is vital for many computer vision tasks where the annotation is missing or scarce.

Unsupervised non-parametric change point detection in quasi-periodic signals

no code implementations7 Feb 2020 Nikolay Shvetsov, Nazar Buzun, Dmitry V. Dylov

We propose a new unsupervised and non-parametric method to detect change points in intricate quasi-periodic signals.
