Representation Learning for Sequence Data with Deep Autoencoding Predictive Components

Junwen Bai, Weiran Wang, Yingbo Zhou +1

We propose Deep Autoencoding Predictive Components (DAPC) -- a self-supervised representation learning method for sequence data, based on the intuition that useful representations…

A Comparison of Pooling Methods on LSTM Models for Rare Acoustic Event Classification

Chieh-Chi Kao, Ming Sun, Weiran Wang +1

Acoustic event classification (AEC) and acoustic event detection (AED) refer to the task of detecting whether specific target events occur in audios. As long short-term memory (LST…

Unsupervised Pre-training of Bidirectional Speech Encoders via Masked Reconstruction

Weiran Wang, Qingming Tang, Karen Livescu

We propose an approach for pre-training speech representations via a masked reconstruction loss. Our pre-trained encoder networks are bidirectional and can therefore be used direct…

Data Techniques For Online End-to-end Speech Recognition

Yang Chen, Weiran Wang, I-Fan Chen +1

Practitioners often need to build ASR systems for new use cases in a short amount of time, given limited in-domain data. While recently developed end-to-end methods largely simplif…

Semi-supervised ASR by End-to-end Self-training

Yang Chen, Weiran Wang, Chao Wang

While deep learning based end-to-end automatic speech recognition (ASR) systems have greatly simplified modeling pipelines, they suffer from the data sparsity issue. In this work,…

Acoustic scene analysis with multi-head attention networks

Weimin Wang, Weiran Wang, Ming Sun +1

Acoustic Scene Classification (ASC) is a challenging task, as a single scene may involve multiple events that contain complex sound patterns. For example, a cooking scene may conta…
