On the properties of some low-parameter models for color reproduction in terms of spectrum transformations and coverage of a color triangle

no code implementations21 Oct 2021 Alexey Kroshnin, Viacheslav Vasilev, Egor Ershov, Denis Shepelev, Dmitry Nikolaev, Mikhail Tchobanou

One of the classical approaches to solving color reproduction problems, such as color adaptation or color space transform, is the use of low-parameter spectral models.

Robust $k$-means Clustering for Distributions with Two Moments

no code implementations6 Feb 2020 Yegor Klochkov, Alexey Kroshnin, Nikita Zhivotovskiy

We consider the robust algorithms for the $k$-means clustering problem where a quantizer is constructed based on $N$ independent observations.

Image Registration and Predictive Modeling: Learning the Metric on the Space of Diffeomorphisms

no code implementations10 Aug 2018 Ayagoz Mussabayeva, Alexey Kroshnin, Anvar Kurmukov, Yulia Dodonova, Li Shen, Shan Cong, Lei Wang, Boris A. Gutman

We present a method for metric optimization in the Large Deformation Diffeomorphic Metric Mapping (LDDMM) framework, by treating the induced Riemannian metric on the space of diffeomorphisms as a kernel in a machine learning context.

Computational Optimal Transport: Complexity by Accelerated Gradient Descent Is Better Than by Sinkhorn's Algorithm

1 code implementation ICML 2018 Pavel Dvurechensky, Alexander Gasnikov, Alexey Kroshnin

We analyze two algorithms for approximating the general optimal transport (OT) distance between two discrete distributions of size $n$, up to accuracy $\varepsilon$.
