Adaptive Model Pruning and Personalization for Federated Learning over Wireless Networks

no code implementations4 Sep 2023 Xiaonan Liu, Tharmalingam Ratnarajah, Mathini Sellathurai, Yonina C. Eldar

This framework splits the learning model into a global part with model pruning shared with all devices to learn data representations and a personalized part to be fine-tuned for a specific device, which adapts the model size during FL to reduce both computation and communication latency and increases the learning accuracy for devices with non-independent and identically distributed data.

Interference and noise cancellation for joint communication radar (JCR) system based on contextual information

no code implementations14 Feb 2023 Christantus O. Nnamani, Mathini Sellathurai

This paper examines the separation of wireless communication and radar signals, thereby guaranteeing cohabitation and acting as a panacea to spectrum sensing.

A Novel Frame Structure for Cloud-Based Audio-Visual Speech Enhancement in Multimodal Hearing-aids

no code implementations24 Oct 2022 Abhijeet Bishnu, Ankit Gupta, Mandar Gogate, Kia Dashtipour, Ahsan Adeel, Amir Hussain, Mathini Sellathurai, Tharmalingam Ratnarajah

In this paper, we design a first of its kind transceiver (PHY layer) prototype for cloud-based audio-visual (AV) speech enhancement (SE) complying with high data rate and low latency requirements of future multimodal hearing assistive technology.
