Image Classification Algorithm for Determining the Light Curve Morphologies of ASAS-SN Eclipsing Binaries

We present a classification of the light curve morphologies of eclipsing binary systems observed by ASAS-SN based on their light curve images. The data of 16500 eclipsing systems having three different classes (detached Algol type, $\beta$ Lyr type, and W UMa type) are collected to construct their light curves. A deep learning algorithm containing the convolutional neural networks is employed on the images to achieve a satisfying classification. A code called ASEBCLASS is written in Python language, and it uses the TensorFlow platform through Keras API to employ the mathematical libraries in the training phase of the model. The architecture consists of four groups of convolutional, activation, maximum pooling layers together with the additional fully connected layers. The results show that our algorithm estimates the morphological class of an external input image data with an accuracy value of 92%.
