Work Hard and Play Hard...

Jierui(Jerry) Xie


I am now with Google.

I am interested in building large-scale intelligent system based on data mining and machine learning techniques for pattern discovery, personalization, recommendation, classification, clustering, behavior prediction, community detection, opinion spreading, big data analysis, privacy enhanced mining etc.

- Collaborative filtering for recommendation and personalization
- Pattern/event/human activity recognition for context-aware application
- Privacy-aware data publishing/analysis
- Community detection in social networks
- Opinion/influence spreading in social networks
- Density based anomaly detection/change detection
- Learning similarity/dissimilarity for categorical data
- Text mining (e.g., burstiness-aware doc search)
- Resource optimization using neural networks

Coming Events:


  • New community detection algorithm: LabelRankT
  • Our stabilized label propagation algorithm for community detection. Here is the news post on Latelier, a French web site devoted to technologies with impact on industry (French,English).


GANXiS (aka SLPA): A linear time community detection software for various network structures (undirected/directed and weighted/unweighted), which is able to discover disjoint, overlapping and evolving/dynamic (with extension to LabelRankT) groups. Meaningful structures have been discovered in real-world social networks (e.g., high school friendship) and gene networks (e.g., Alzheimer's disease).(download and more info)
