Research Interests

• Semi-Supervised Learning: manually labeled samples usually are expensive and scarce. It is economical to train classifiers (shallow or deep models) using a small amount of labeled samples and aboundant, easily available unlabeled samples.

• Deep Neural Networks: understanding brain learning mechanism and developing highly effective AI algorithms are a pair of dual problems. It is interesting to explore the foundamental neural learning rules shared across biological and artificial intelligence.
