Research Area

Currently, I am working on neural conversational AI:

  • natural language understanding: Natural language understanding parses (speech) input to the semantic meaning, including intent classification and slot tagging. The tough challenge is the diversity of natural language and poor supervision resources. Domain adaption and transfer learning are attracting more attention.
  • dialog policy learning: We take the task-oriented dialogue as the optimal decision-making process to find optimal policy $\pi$, which could be modeled as a typical reinforcement learning(RL) problem. By maximizing average long-term reward, we could learn the optimal action $a$ to state $s$. Although some challenges remain, such as efficient sampling, reward setting, and dialogue evaluation metric, etc.
  • adversarial learning: Adversarial learning in natural language processing has achieved great success in many aspects, especially for semi-supervision learning, transfer learning from high-resource to low-resource, and active learning, etc. Now I’m focusing on adversarial learning in domain adaption and transfer learning.
