Optimizing Age-of-Information in Adversarial Environments with Channel State Information
Avijit Mandal, Rajarshi Bhattacharjee, Abhishek Sinha
This paper considers a multi-user downlink scheduling problem with access to the channel state information at the transmitter (CSIT) to minimize the Age-of-Information (AoI) in a n…
Competitive Algorithms for Minimizing the Maximum Age-of-Information
Rajarshi Bhattacharjee, Abhishek Sinha
In this short paper, we consider the problem of designing a near-optimal competitive scheduling policy for mobile users, to maximize the freshness of available information unif…
Fundamental Limits of Online Network-Caching
Rajarshi Bhattacharjee, Subhankar Banerjee, Abhishek Sinha
Optimal caching of files in a content distribution network (CDN) is a problem of fundamental and growing commercial interest. Although many different caching algorithms are in use…
Fundamental Limits of Age-of-Information in Stationary and Non-stationary Environments
Subhankar Banerjee, Rajarshi Bhattacharjee, Abhishek Sinha
We study the multi-user scheduling problem for minimizing the Age of Information (AoI) in cellular wireless networks under stationary and non-stationary regimes. We derive fundamen…
Online Algorithms for Multiclass Classification using Partial Labels
Rajarshi Bhattacharjee, Naresh Manwani
In this paper, we propose online algorithms for multiclass classification using partial labels. We propose two variants of Perceptron called Avg Perceptron and Max Perceptron to de…
