Accurate Block Quantization in LLMs with Outliers

no code implementations29 Mar 2024 Nikita Trukhanov, Ilya Soloveychik

It made evident the colossal shortage of dedicated hardware capable of efficient and fast processing of the involved compute and memory movement.

Block Format Error Bounds and Optimal Block Size Selection

no code implementations11 Oct 2022 Ilya Soloveychik, Ilya Lyubomirsky, Xin Wang, Sudeep Bhoja

This measure allows us to determine the optimal parameters, such as the block size, yielding highest accuracy.

A Robust Test for Elliptical Symmetry

no code implementations5 Jun 2020 Ilya Soloveychik

Ellipticity GoF tests are usually hard to analyze and often their statistical power is not particularly strong.

Stationary Geometric Graphical Model Selection

no code implementations10 Jun 2018 Ilya Soloveychik, Vahid Tarokh

We consider the problem of model selection in Gaussian Markov fields in the sample deficient scenario.

Region Detection in Markov Random Fields: Gaussian Case

no code implementations12 Feb 2018 Ilya Soloveychik, Vahid Tarokh

Assuming that the entire graph can be partitioned into a number of spatial regions with similar edge parameters and reasonably regular boundaries, we develop new information-theoretic sample complexity bounds and show that a bounded number of samples can be sufficient to consistently recover these regions.

Joint Inverse Covariances Estimation with Mutual Linear Structure

no code implementations20 Nov 2015 Ilya Soloveychik, Ami Wiesel

We consider the problem of joint estimation of structured inverse covariance matrices.

Tyler's Covariance Matrix Estimator in Elliptical Models with Convex Structure

no code implementations7 Apr 2014 Ilya Soloveychik, Ami Wiesel

We address structured covariance estimation in elliptical distributions by assuming that the covariance is a priori known to belong to a given convex set, e. g., the set of Toeplitz or banded matrices.

Group Symmetry and non-Gaussian Covariance Estimation

no code implementations18 Jun 2013 Ilya Soloveychik, Ami Wiesel

We consider robust covariance estimation with group symmetry constraints.
