Yun Chi

What is he best known for?

The fields of study he is best known for:

• Operating system
• Database
• Artificial intelligence

Yun Chi spends much of his time researching Data mining, Artificial intelligence, Machine learning, Social network and Tree. Particularly relevant to Data stream mining is his body of work in Data mining. His work in the fields of Artificial intelligence, such as Bayesian inference, Stochastic block model, Posterior probability and Word, intersects with other areas such as Projection.

When carried out as part of a general Machine learning research project, his work on Bayesian network is frequently linked to work in Point estimation, therefore connecting diverse disciplines of study. His research integrates issues of Time complexity and Blogosphere in his study of Social network. His Tree study integrates concerns from other disciplines, such as Transaction processing and Data structure.

His most cited work include:

• Facetnet: a framework for analyzing communities and their evolutions in dynamic networks (338 citations)
• Evolutionary spectral clustering by incorporating temporal smoothness (321 citations)
• Combining link and content for community detection: a discriminative approach (305 citations)

What are the main themes of his work throughout his whole career to date?

Yun Chi mainly focuses on Data mining, Information retrieval, Artificial intelligence, Cloud computing and Database. The various areas that Yun Chi examines in his Data mining study include Tree, Data stream clustering and Correlation clustering, Canopy clustering algorithm. The concepts of his Information retrieval study are interwoven with issues in Web page, Web mining and Document clustering.

His Artificial intelligence research is multidisciplinary, relying on both Machine learning and Pattern recognition. His Machine learning research is multidisciplinary, incorporating elements of Time complexity, Social network and Bayesian inference. His study in Cloud computing is interdisciplinary in nature, drawing from both Workload and Computer network.
