Wei Ding . UMass Boston . Discriminating Patterns 2
Geospatial Discriminating Patterns
Spatial Association Rules Spatial Co-Location Patterns Regional Association Patterns
Solved or Almost Solved Spatial Association Rules [Koperski & Han 1995]
Spatial Co-Location Patterns [Huang & Shekhar]
Regional Association Patterns [Ding & Eick]
[huang2004]
Wei Ding . UMass Boston . Discriminating Patterns 3
Failed & Missing Modeling causal relationship among
geo-variables Complex chain of mutual interactions Nonlinearity and spatial variability
Efficient pattern summarization Laziness: large amount of patterns “super-patterns”
Robust & practical knowledge discovery tools to build empirical models for domain experts
Wei Ding . UMass Boston . Discriminating Patterns 4
What is next?Provide the scientific community with an efficient tool for auto-analyzing the root causes behind observed patterns in geospatial data.
