Progressive unsupervised domain adaptation for ASR using ensemble models and multi-stage training

no code implementations7 Feb 2024 Rehan Ahmad, Muhammad Umar Farooq, Thomas Hain

A previous study has shown the effectiveness of using ensemble teacher models in T/S training for unsupervised domain adaptation (UDA) but its performance still lags behind compared to the model trained on in-domain data.

MUST: A Multilingual Student-Teacher Learning approach for low-resource speech recognition

no code implementations29 Oct 2023 Muhammad Umar Farooq, Rehan Ahmad, Thomas Hain

However, a limitation of KD training is that the student model classes must be a proper or improper subset of the teacher model classes.

Motion Corrected Multishot MRI Reconstruction Using Generative Networks with Sensitivity Encoding

no code implementations20 Feb 2019 Muhammad Usman, Muhammad Umar Farooq, Siddique Latif, Muhammad Asim, Junaid Qadir

The downside of multishot MRI is that it is very sensitive to subject motion and even small amounts of motion during the scan can produce artifacts in the final MR image that may cause misdiagnosis.
