A Ranking Approach for Measuring Calibration
Anirban Chatterjee, Rina Foygel Barber
When providing forecasted probabilities with a predictive model, the ideal model offers perfect calibration: the true probability of the outcome (i.e., the probability that )…
Dynamics of viable dark energy models in the presence of Curvature-Matter interactions
Anirban Chatterjee, Rahul Roy, Sayantan Dey +1
In this study, we analyze the dynamics of the interaction between dark matter and curvature-driven dark energy in viable gravity models using the framework of dynamical syst…
Boosting the Power of Kernel Two-Sample Tests
Anirban Chatterjee, Bhaswar B. Bhattacharya
The kernel two-sample test based on the maximum mean discrepancy (MMD) is one of the most popular methods for detecting differences between two distributions over general metric sp…
Detecting Planted Partition in Sparse Multi-Layer Networks
Anirban Chatterjee, Sagnik Nandy, Ritwik Sadhu
Multilayer networks are used to represent the interdependence between the relational data of individuals interacting with each other via different types of relationships. To study…
Detecting Concept Drift in the Presence of Sparsity -- A Case Study of Automated Change Risk Assessment System
Vishwas Choudhary, Binay Gupta, Anirban Chatterjee +3
Missing values, widely called as \textit{sparsity} in literature, is a common characteristic of many real-world datasets. Many imputation methods have been proposed to address this…
Dynamical Stability in presence of non-minimal derivative dependent coupling of -essence field with a relativistic fluid
Kaushik Bhattacharya, Anirban Chatterjee, Saddam Hussain
In this paper we investigate a non-minimal, space-time derivative dependent, coupling between the -essence field and a relativistic fluid using a variational approach. The deriv…
Dynamical analysis of -essence cosmology in the light of Supernova Ia observations
Anirban Chatterjee, Abhijit Bandyopadhyay, Biswajit Jana
In this paper, we analyse the JLA data on Supernova observations in the context of essence dark energy model with Lagrangian , with a constant potential and the dy…
Dynamical stability of K-essence field interacting non-minimally with a perfect fluid
Anirban Chatterjee, Saddam Hussain, Kaushik Bhattacharya
We study models of non-minimally coupled relativistic fluid and -essence scalar field in the background of a flat Friedmann-Lemaitre-Robertson-Walker universe. The non-minimal c…
Fluctuations of Subgraph Counts in Graphon Based Random Graphs
Bhaswar B. Bhattacharya, Anirban Chatterjee, Svante Janson
Given a graphon and a finite simple graph , with vertex set , denote by the number of copies of in a -random graph on vertices. The asymptotic d…
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
