Natural Language Processing Lab

The NLP Lab at VT is mainly working on the fields of Natural Language Processing, Multimodal Learning, and Machine Learning. We are particularly interested in building efficient models and benchmarks that can encourage machines to perform human-level intelligence. We are grateful to NSF, DARPA, IARPA, U.S. Air Force, Amazon (AWS and Alexa AI), Meta AI, Google, Intuit and Washington Post for supporting our research!
