Automatic Speech Recognition System-Independent Word Error Rate Estimation
Chanho Park, Mingjie Chen, Thomas Hain
Word error rate (WER) is a metric used to evaluate the quality of transcriptions produced by Automatic Speech Recognition (ASR) systems. In many applications, it is of interest to…
SignSGD with Federated Defense: Harnessing Adversarial Attacks through Gradient Sign Decoding
Chanho Park, Namyoon Lee
Distributed learning is an effective approach to accelerate model training using multiple workers. However, substantial communication delays emerge between workers and a parameter…
Sparse-SignSGD with Majority Vote for Communication-Efficient Distributed Learning
Chanho Park, Namyoon Lee
The training efficiency of complex deep learning models can be significantly improved through the use of distributed optimization. However, this process is often hindered by a larg…
Unsupervised data selection for Speech Recognition with contrastive loss ratios
Chanho Park, Rehan Ahmad, Thomas Hain
This paper proposes an unsupervised data selection method by using a submodular function based on contrastive loss ratios of target and training data sets. A model using a contrast…
