On Statistical Properties of A Veracity Scoring Method for Spatial Data
Arnab Chakraborty, Soumendra N. Lahiri
Measuring veracity or reliability of noisy data is of utmost importance, especially in the scenarios where the information are gathered through automated systems. In a recent paper…
A Statistical Analysis of Noisy Crowdsourced Weather Data
Arnab Chakraborty, Soumendra Nath Lahiri, Alyson Wilson
Spatial prediction of weather-elements like temperature, precipitation, and barometric pressure are generally based on satellite imagery or data collected at ground-stations. None…
Data Reduction in Markov model using EM algorithm
Atanu Kumar Ghosh, Arnab Chakraborty
This paper describes a data reduction technique in case of a markov chain of specified order. Instead of observing all the transitions in a markov chain we record only a few of the…
Congestion Barcodes: Exploring the Topology of Urban Congestion Using Persistent Homology
Yu Wu, Gabriel Shindnes, Vaibhav Karve +4
This work presents a new method to quantify connectivity in transportation networks. Inspired by the field of topological data analysis, we propose a novel approach to explore the…
Compressive Sampling Using EM Algorithm
Atanu Kumar Ghosh, Arnab Chakraborty
Conventional approaches of sampling signals follow the celebrated theorem of Nyquist and Shannon. Compressive sampling, introduced by Donoho, Romberg and Tao, is a new paradigm tha…
