Patterns in Data Mining

How are the patterns expressed? Useful patterns allow us to make nontrivial predictions on new data. There are two extremes for the expression of a pattern:
- as a black box whose innards are effectively incomprehensible and
- as a transparent box whose construction reveals the structure of the pattern.
The difference is whether or not the patterns that are mined are represented in terms of a structure that can be examined, reasoned about, and used to inform future decisions.
Such patternsare called structural because they capture the decision structure in an explicit way
