Ta-Chung Chi 🐸

I am a 5th-year PhD student at the Language Technologies Institute in the School of Computer Science at Carnegie Mellon University advised by Alexander I. Rudnicky. My research interests lie in the field of length extrapolatable Transformers, dialogue systems, and related NLP topics.
