Detecting Outliers in SDSS using Convolutional Neural Network

Sharma, K; Kembhavi, Ajit; Kembhavi, Aniruddha; Sivarani, T; Abraham, S. (Societe Royale des Sciences de Liege, 2019-10)

We propose an automated algorithm based on Convolutional Neural Network (CNN) for the detection of peculiar objects in large databases using their spectral observations. A convolutional neural network is a class of ...
Photometric identification of compact galaxies, stars, and quasars using multiple neural networks

Chaini, Siddharth; Bagul, Atharva; Deshpande, Anish; Gondkar, Rishi; Sharma, Kaushal; Vivek, M; Kembhavi, Ajit (Oxford University Press on behalf of Royal Astronomical Society, 2023-01)

We present MargNet, a deep learning-based classifier for identifying stars, quasars, and compact galaxies using photometric parameters and images from the Sloan Digital Sky Survey Data Release 16 catalogue. MargNet consists ...
