Domain Adaptation via Minimax Entropy for Real/Bogus Classification of Astronomical Alerts

An important number of these alerts analysis of multiple massive datasets in real time, are bogus artifacts created by the image reduction pipelines, prompting the development of multi-stream machine hence, the importance of creating real/bogus classification learning models. In this work, we study algorithms which have proven to be extremely useful for Domain Adaptation (DA) for real/bogus classification detecting real astrophysical phenomena. During the last of astronomical alerts using four different decade, most of these algorithms have been based on Convolutional datasets: HiTS, DES, ATLAS, and ZTF. We Neural Networks (Cabrera-Vives et al., 2016; 2017; study the domain shift between these datasets, Reyes et al., 2018; Duev et al., 2019; Turpin et al., 2020; Yin and improve a naive deep learning classification et al., 2021; Rabeendran & Denneau, 2021) which need a model by using a fine tuning approach and significant amount of data to be trained.
