Executing Causal Structure Learning with Linear-Attention Transformers

Amartya Roy, Sayar Karmakar

Transformers can execute algorithms on data given in their input. We ask whether they can do the same for causal discovery. We study a standard continuous method that repeatedly up…

A Characterization of the -tests Under Nearly Integrated Nearly White Noise

Aidan Wardak, Sayar Karmakar

We derive the limiting distributions of the -test family of unit root statistics in the nearly integrated nearly white noise (NINW) framework introduced by Nabeya and Perron (19…

Nonparametric regression of spatio-temporal data using infinite-dimensional covariates

Subhrajyoty Roy, Soudeep Deb, Sayar Karmakar +1

In spatio-temporal analysis, we often record data at specific time intervals but with varying spatial locations between these timepoints. We propose a conditional model to analyze…

Fast localization of anomalous patches in spatial data under dependence

Soham Bonnerjee, Sayar Karmakar, George Michailidis

We propose a scalable, provably accurate method for localizing an unknown number of multiple axis-aligned anomalous patches in spatial data under a general class of spatial depende…
