Auxiliary Network-Enabled Attack Detection and Resilient Control of Islanded AC Microgrid

no code implementations30 Dec 2023 Vaibhav Vaishnav, Anoop Jain, Dushyant Sharma

It is shown that the in situ presence of a concealed auxiliary layer not only guarantees resilience against stealthy bounded attacks on both frequency and power-sharing but also facilitates a network-enabled attack identification mechanism.

Spatial Processing Front-End For Distant ASR Exploiting Self-Attention Channel Combinator

no code implementations25 Mar 2022 Dushyant Sharma, Rong Gong, James Fosburgh, Stanislav Yu. Kruchinin, Patrick A. Naylor, Ljubomir Milanovic

We present a novel multi-channel front-end based on channel shortening with theWeighted Prediction Error (WPE) method followed by a fixed MVDR beamformer used in combination with a recently proposed self-attention-based channel combination (SACC) scheme, for tackling the distant ASR problem.

ChannelAugment: Improving generalization of multi-channel ASR by training with input channel randomization

no code implementations23 Sep 2021 Marco Gaudesi, Felix Weninger, Dushyant Sharma, Puming Zhan

End-to-end (E2E) multi-channel ASR systems show state-of-the-art performance in far-field ASR tasks by joint training of a multi-channel front-end along with the ASR model.

Self-Attention Channel Combinator Frontend for End-to-End Multichannel Far-field Speech Recognition

no code implementations10 Sep 2021 Rong Gong, Carl Quillen, Dushyant Sharma, Andrew Goderre, José Laínez, Ljubomir Milanović

When a sufficiently large far-field training data is presented, jointly optimizing a multichannel frontend and an end-to-end (E2E) Automatic Speech Recognition (ASR) backend shows promising results.
