How to Estimate Model Transferability of Pre-Trained Speech Models?

1 code implementation1 Jun 2023 Zih-Ching Chen, Chao-Han Huck Yang, Bo Li, Yu Zhang, Nanxin Chen, Shuo-Yiin Chang, Rohit Prabhavalkar, Hung-Yi Lee, Tara N. Sainath

In this work, we introduce a "score-based assessment" framework for estimating the transferability of pre-trained speech models (PSMs) for fine-tuning target tasks.

CHAPTER: Exploiting Convolutional Neural Network Adapters for Self-supervised Speech Models

no code implementations1 Dec 2022 Zih-Ching Chen, Yu-Shun Sung, Hung-Yi Lee

However, such efficient tuning techniques only provide adaptation at the transformer layer, but failed to perform adaptation at the feature extractor.

Learning Facial Liveness Representation for Domain Generalized Face Anti-spoofing

no code implementations16 Aug 2022 Zih-Ching Chen, Lin-Hsi Tsao, Chin-Lun Fu, Shang-Fu Chen, Yu-Chiang Frank Wang

Face anti-spoofing (FAS) aims at distinguishing face spoof attacks from the authentic ones, which is typically approached by learning proper models for performing the associated classification task.
