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…

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…
