On the Optimal Number of Grids for Differentially Private Non-Interactive -Means Clustering
Gokularam Muthukrishnan, Anshoo Tandon
Differentially private -means clustering enables releasing cluster centers derived from a dataset while protecting the privacy of the individuals. Non-interactive clustering tec…
Integrating OTFS in Airplane-Aided Next-Generation Networking
Ashok S Kumar, Shashank Shekhar, Gokularam Muthukrishnan +2
Next-generation networks explore the opportunistic assistance of airliner/high-altitude platforms (HAPs) in delivering high data rates for terrestrial networks to ensure consistent…
Tuning-Free Online Robust Principal Component Analysis through Implicit Regularization
Lakshmi Jayalal, Gokularam Muthukrishnan, Sheetal Kalyani
The performance of the standard Online Robust Principal Component Analysis (OR-PCA) technique depends on the optimum tuning of the explicit regularizers and this tuning is dataset…
Source Enumeration using the Distribution of Angles: A Robust and Parameter-Free Approach
Gokularam Muthukrishnan, Siva Shanmugam, Sheetal Kalyani
Source enumeration, the task of estimating the number of sources from the signal received by the array of antennas, is a critical problem in array signal processing. Numerous metho…
Differential Privacy with Higher Utility by Exploiting Coordinate-wise Disparity: Laplace Mechanism Can Beat Gaussian in High Dimensions
Gokularam Muthukrishnan, Sheetal Kalyani
Conventionally, in a differentially private additive noise mechanism, independent and identically distributed (i.i.d.) noise samples are added to each coordinate of the response. I…
