The main research interests of LAMDA include machine learning, data mining, information retrieval, pattern recognition, neural computation, evolutionary computation, and some other related areas. Currently our research mainly involves: ensemble learning, semi-supervised learning, multi-instance and multi-label learning, cost-sensitive and class-imbalance learning, dimensionality reduction and feature selection, theoretical foundations of evolutionary computation, improving comprehensibility of learning sytems, content-based image retrieval, web search and mining, face recognition, computer-aided medical diagnosis, etc.

This course covers recent research on the structure and analysis of such networks, and on models that abstract their basic properties. Topics include combinatorial and probabilistic techniques for link analysis, centralized and decentralized search algorithms, network models based on random graphs, and connections with work in the social sciences.
