Introducing the Huber mechanism for differentially private low-rank matrix completion

no code implementations16 Jun 2022 R Adithya Gowtham, Gokularam M, Thulasi Tholeti, Sheetal Kalyani

We also propose using the Iteratively Re-Weighted Least Squares algorithm to complete low-rank matrices and study the performance of different noise mechanisms in both synthetic and real datasets.

Green DetNet: Computation and Memory efficient DetNet using Smart Compression and Training

no code implementations20 Mar 2020 Nancy Nayak, Thulasi Tholeti, Muralikrishnan Srinivasan, Sheetal Kalyani

This paper introduces an incremental training framework for compressing popular Deep Neural Network (DNN) based unfolded multiple-input-multiple-output (MIMO) detection algorithms like DetNet.

Concavifiability and convergence: necessary and sufficient conditions for gradient descent analysis

no code implementations28 May 2019 Thulasi Tholeti, Sheetal Kalyani

We show that concavifiability is a necessary and sufficient condition to satisfy the upper quadratic approximation which is key in proving that the objective function decreases after every gradient descent update.

A Centralized Multi-stage Non-parametric Learning Algorithm for Opportunistic Spectrum Access

no code implementations30 Apr 2018 Thulasi Tholeti, Vishnu Raj, Sheetal Kalyani

Owing to the ever-increasing demand in wireless spectrum, Cognitive Radio (CR) was introduced as a technique to attain high spectral efficiency.

Spectrum Access In Cognitive Radio Using A Two Stage Reinforcement Learning Approach

no code implementations31 Jul 2017 Vishnu Raj, Irene Dias, Thulasi Tholeti, Sheetal Kalyani

Here, we propose an algorithm to not only select a channel for data transmission but also to predict how long the channel will remain unoccupied so that the time spent on channel sensing can be minimized.
