Wasserstein Projection Pursuit of Non-Gaussian Signals
Satyaki Mukherjee, Soumendu Sundar Mukherjee, Debarghya Ghoshdastidar
We consider the general dimensionality reduction problem of locating in a high-dimensional data cloud, a -dimensional non-Gaussian subspace of interesting features. We use a pro…
Concentration inequalities for correlated network-valued processes with applications to community estimation and changepoint analysis
Sayak Chatterjee, Shirshendu Chatterjee, Soumendu Sundar Mukherjee +2
Network-valued time series are currently a common form of network data. However, the study of the aggregate behavior of network sequences generated from network-valued stochastic p…
Limiting spectral distribution of a class of Hankel type random matrices
Anirban Basak, Arup Bose, Soumendu Sundar Mukherjee
We consider an indexed class of real symmetric random matrices which generalize the symmetric Hankel and Reverse Circulant matrices. We show that the limiting spectral distribution…
Bulk behaviour of Schur-Hadamard products of symmetric random matrices
Arup Bose, Soumendu Sundar Mukherjee
We develop a general method for establishing the existence of the Limiting Spectral Distributions (LSD) of Schur-Hadamard products of independent symmetric patterned random matrice…
