On-Line Learning of Linear Dynamical Systems: Exponential Forgetting in Kalman Filters

1 code implementation AAAI 2019 Mark Kozdoba, Jakub Marecek, Tigran Tchrakian, Shie Mannor

Based on this insight, we devise an on-line algorithm for improper learning of a linear dynamical system (LDS), which considers only a few most recent observations.

Robust Spectral Filtering and Anomaly Detection

no code implementations3 Aug 2018 Jakub Marecek, Tigran Tchrakian

We consider a setting, where the output of a linear dynamical system (LDS) is, with an unknown but fixed probability, replaced by noise.

Where computer vision can aid physics: dynamic cloud motion forecasting from satellite images

no code implementations30 Sep 2017 Sergiy Zhuk, Tigran Tchrakian, Albert Akhriev, Siyuan Lu, Hendrik Hamann

The prediction phase consists of utilizing a linear transport equation, which describes the propagation of COD images in the fluid flow predicted by NSE, to estimate the future motion of the COD images.
