Welcome! I am Tiancheng Zhao (赵天成), a research scientist at Binjiang Institute of Zhejiang University, and I also lead the Om Artificial Intelligence Laboratory (Om AI Lab). I received my Ph.D. in Computer Science from Carnegie Mellon University , Language Technologies Institute, advised by Prof. Maxine Eskenazi. My PhD dissertation Learning to Converse With Latent Actions is one of the early work in end-to-end generative model for conversational AI, advised by Prof. Maxine Eskenazi , Prof. Louis-Philippe Morency , Prof. William W. Cohen and Dr. Dilek Hakkani-Tur . Prior to that, I obtained my bachelor degree in Electrical Engineering from University of California, Los Angeles with Summa Cum Laude and worked on speech signal processing, advised by Prof. Abeer Alwan .
I am interested in multimodal machine learning and human computer interaction. My current focus is to develop computational building blocks that connect the machine with people by innovating with the latest machine learning methods and practical system implementations.The technical challenges of this effort includes:
- Efficient Learning: develop learning algorithms that enable computers to master new skills more effectively (few-shot/zero-shot) from a variety types of training data, e.g. supervised labels, rewards, meta learning, etc.
- Multimodal Learning: build multimodal machine learning models to establish cross-modal representations that better recognize or generate high-dimensional multimodal data.
- From Perception to Action: learn better decision-making policies that deliver the optimal control output based on deep understanding of the state space.
My research outcome has a wide range of real-world applications, including conversational agents, autonomous robots, information retrieval and many other AI applications.
