Bayesian Non-parametric Simultaneous Quantile Regression for Complete and Grid Data
Priyam Das, Subhashis Ghosal
In this paper, we consider Bayesian methods for non-parametric quantile regressions with multiple continuous predictors ranging values in the unit interval. In the first method, th…
Bayesian Quantile Regression Using Random B-spline Series Prior
Priyam Das, Subhashis Ghoshal
We consider a Bayesian method for simultaneous quantile regression on a real variable. By monotone transformation, we can make both the response variable and the predictor variable…
Analyzing Ozone Concentration by Bayesian Spatio-temporal Quantile Regression
Priyam Das, Subhashis Ghosal
Ground level Ozone is one of the six common air-pollutants on which the EPA has set national air quality standards. In order to capture the spatio-temporal trend of 1-hour and 8-ho…
Recursive Modified Pattern Search on High-dimensional Simplex : A Blackbox Optimization Technique
Priyam Das
In this paper, a novel derivative-free pattern search based algorithm for Black-box optimization is proposed over a simplex constrained parameter space. At each iteration, starting…
Black-box optimization on hyper-rectangle using Recursive Modified Pattern Search and application to ROC-based Classification Problem
Priyam Das
In statistics, it is common to encounter multi-modal and non-smooth likelihood (or objective function) maximization problems, where the parameters have known upper and lower bounds…
Collectively induced many-vortices topology via rotatory Dicke quantum phase transition
Priyam Das, Mehmet Emre Tasgin, Ozgur E. Mustecaplioglu
We examine the superradiance of a Bose-Einstein condensate pumped with a Laguerre-Gaussian laser of high winding number, e.g., . The laser beam transfers its orbital angu…
