Speaker’s Title: Associate Professor, Department of Electrical Engineering

Speaker’s Affiliation: National Taiwan University (NTU)

Seminar Title: How Versatile are Self-Supervised Models?

Abstract: Self-supervised learning (SSL) has shown to be vital for advancing research in natural language processing (NLP), computer vision (CV), and speech processing. The paradigm pre-trains a shared model on large volumes of unlabeled data and achieves state-of-the-art for various tasks with minimal adaptation. This talk first introduces the Speech processing Universal PERformance Benchmark (SUPERB), which is a leaderboard to benchmark the performance of SSL model across a wide range of speech processing tasks. The results on SUPERB demonstrates that SSL representations show competitive generalizability across speech processing tasks. This talk will also share some surprising new findings that SSL models pretrained from text are helpful for non-text token sequence classification data, including amino acid, DNA, and music.

Biographical Sketch of the Speaker: ​​​​​​​Hung-yi Lee is an associate professor of the Department of Electrical Engineering of National Taiwan University (NTU), with a joint appointment at the Department of Computer Science & Information Engineering of the university. His recent research focuses on developing technology that can reduce the requirement of annotated data for speech processing (including voice conversion and speech recognition) and natural language processing (including abstractive summarization and question answering).
