Abstract
The discovery of cosmic microwave background (CMB) was a paradigm shift in
the study and fundamental understanding of the early universe and also the Big
Bang phenomenon. Cosmic microwave background is one of the richest and
intriguing sources of information available to cosmologists. Although there are
some well established statistical methods for the analysis of CMB, here we
explore the use of deep learning in this respect. We correlate the baryon
density obtained from the power spectrum of CMB temperature maps with the
corresponding map and form the dataset for training the neural network model.
We analyze the accuracy with which the model is able to predict the results
from a relatively abstract dataset considering the fact that CMB is a Gaussian
random field. CMB is anisotropic due to temperature fluctuations at small
scales but on a larger scale CMB is considered isotropic, here we analyze the
isotropy of CMB by training the model with CMB maps centered at different
galactic coordinates and compare the predictions of neural network models.
