Interest
Time is important, isn't it? My current research interest is
- Temporal pattern mining: Given a Time series data, Sequence data and or Interval-based event sequences, design an efficient data mining algorithm to discover the frequent pattern efficiently. The discover pattern can be used for performing correlation analysis or designing a classifier based on frequent pattern. (IEMiner & IEClassifier)
- Time Series Correlation analysis
- Time series Indexing for similarity search
- Scaling all pair similarity search
- Multi-dimension star joins
In Progress
- Multi-dimensions Multi-tables similarity join
