WiNeRT: Towards Neural Ray Tracing for Wireless Channel Modelling and Differentiable Simulations

Tribhuvanesh Orekondy, Pratik Kumar, Shreya Kadambi, Hao Ye, Joseph Soriaga, Arash Behboodi

ICLR 2023poster

In this paper, we work towards a neural surrogate to model wireless electro-magnetic propagation effects in indoor environments. Such neural surrogates provide a fast, differentiable, and continuous representation of the environment and enables end-to-end optimization for downstream tasks (e.g., net…

Investigation of Robustness of Hubert Features from Different Layers to Domain, Accent and Language Variations

Pratik Kumar, Vrunda N. Sukhadia, Srinivasan Umesh

ICASSP 2022accepted

In this paper, we investigate the use of pre-trained HuBERT model to build downstream Automatic Speech Recognition (ASR) models using data that have differences in domain, accent and even language. We use the standard ESPnet recipe with HuBERT as pre-trained models whose output is fed as input featu…
