Neural networks as well as other methods of machine learning (ML) are known to be highly
efficient in different classification tasks, including classification of images and videos. Mini-
EUSO is a wide-field-of-view imaging telescope that operates onboard the International Space
Station since 2019 collecting data on miscellaneous processes that take place in the atmosphere of Earth in the UV range. Here we briefly present our results on the development of ML-based approaches for recognition and classification of track-like signals in the Mini-EUSO data, among them meteors, space debris and signals the light curves and kinematics of which are similar to those expected from extensive air showers generated by ultra-high-energy cosmic rays. We show that even simple neural networks demonstrate impressive performance in solving these tasks.
