Finding Anomalous Periodic Time Series: An Application to Catalogs of Periodic Variable Stars
Umaa Rebbapragada, Pavlos Protopapas, Carla E. Brodley +1
Catalogs of periodic variable stars contain large numbers of periodic light-curves (photometric time series data from the astrophysics domain). Separating anomalous objects from we…
Event Discovery in Time Series
Dan Preston, Pavlos Protopapas, Carla Brodley
The discovery of events in time series can have important implications, such as identifying microlensing events in astronomical surveys, or changes in a patient's electrocardiogram…
De-Trending Time Series for Astronomical Variability Surveys
Dae-Won Kim, Pavlos Protopapas, Charles Alcock +2
We present a de-trending algorithm for the removal of trends in time series. Trends in time series could be caused by various systematic and random noise sources such as cloud pass…
