Online detection of local abrupt changes in high-dimensional Gaussian graphical models

no code implementations16 Mar 2020 Hossein Keshavarz, George Michailidis

The problem of identifying change points in high-dimensional Gaussian graphical models (GGMs) in an online fashion is of interest, due to new applications in biology, economics and social sciences.

A Deep Learning-Based Approach for Measuring the Domain Similarity of Persian Texts

1 code implementation12 Sep 2019 Hossein Keshavarz, Shohreh Tabatabayi Seifi, Mohammad Izadi

We generated a significant number of paired texts from this dataset and assigned each pair a score from 0 to 3, which demonstrates the degree of similarity between the domains of the pair.

Sequential change-point detection in high-dimensional Gaussian graphical models

no code implementations20 Jun 2018 Hossein Keshavarz, George Michailidis, Yves Atchade

High dimensional piecewise stationary graphical models represent a versatile class for modelling time varying networks arising in diverse application areas, including biology, economics, and social sciences.

Change Point Detection

Optimal change point detection in Gaussian processes

no code implementations3 Jun 2015 Hossein Keshavarz, Clayton Scott, XuanLong Nguyen

By contrast, the standard CUSUM method, which does not account for the covariance structure, is shown to be asymptotically optimal only in the increasing domain.
