I am Wei Zhang, working on artificial neural networks and natural language processing at AI Foundations Lab in IBM Research. My interest is neural networks with external memory and/or attentions. I got my masters of language technologies from CMU LTI in 2014. I was leading a small team at Watson working on machine reading comprehension. Now a full-time independent researcher.

Research Interests

  • End-to-end recurrent neural networks augmented with Memory and Attention
  • algorithm learning
  • Multi-task learning
  • reinfocement learning
  • Neural machine comprehension and Natural language inference and reasoning
  • Structured prediction
