Spectral properties of the Laplacian of a generalized Wigner matrix
Anirban Chatterjee, Rajat Subhra Hazra
In this article we consider the spectrum of a Laplacian matrix, also known as the Markov matrix, under the independence assumption. We assume that the entries have a variance profi…
Drift-Adjusted And Arbitrated Ensemble Framework For Time Series Forecasting
Anirban Chatterjee, Subhadip Paul, Uddipto Dutta +1
Time Series Forecasting is at the core of many practical applications such as sales forecasting for business, rainfall forecasting for agriculture and many others. Though this prob…
Time-dependent diffusive interactions between dark matter and dark energy in the context of essence cosmology
Abhijit Bandyopadhyay, Anirban Chatterjee
We investigated the scenario of time-dependent diffusive interaction between dark matter and dark energy and showed that such a model can be accommodated within the observations of…
Probing Dark-ALP Portals at Future Colliders
Sanjoy Biswas, Anirban Chatterjee, Emidio Gabrielli +1
We study portal interactions connecting visible and dark sectors, and involving local interactions of a photon, a dark photon and a axion-like particle (ALP) at future col…
Semi-Bagging Based Deep Neural Architecture to Extract Text from High Entropy Images
Pranay Dugar, Anirban Chatterjee, Rajesh Shreedhar Bhat +1
Extracting texts of various size and shape from images containing multiple objects is an important problem in many contexts, especially, in connection to e-commerce, augmented real…
Implications of JLA data for essence model of dark energy with given equation of state
Abhijit Bandyopadhyay, Anirban Chatterjee
We investigated implications of recently released `Joint Light-curve Analysis' (JLA) supernova Ia (SNe Ia) data for dark energy models with time varying equation of state of dark e…
