В этом выпуске Astro Channel расскажет про расширение границ Солнечной системы, открытие планет и поясов астероидов. Ну и конечно же будут наблюдения в любительский телескоп. В этот раз главной целью станут карликовые планеты - Макемаке и Хаумеа.

Уважаемые коллеги,

ТЕМА: Rare events in Astronomy
Addressing Imbalanced Data in FRB Classification

АННОТАЦИЯ: Currently, astronomy is experiencing a boom in big data, and the use of machine learning and deep learning is spreading like wildfire. Nevertheless, many traditional statistical techniques remain applicable and may be better suited depending on the type of data.
I will present research demonstrating how understanding the structure of the data provides insight into its treatment—particularly when considering rare events in the study of Fast Radio Bursts (FRBs) using data from the CHIME telescope. FRBs are powerful, millisecond-long radio signals originating from distant galaxies—enigmatic cosmic flashes with unknown origins. The classification approach presented in this talk utilizes weighted logistic regression to address data imbalance, offering new insights into classifying FRBs as repeaters or non-repeaters.

This talk promises a compelling exploration of FRB classification and machine learning strategies.
