Condensed Representation of EPs and Patterns Quantified by Frequency-Based Measures
Emerging patterns (EPs) are associations of features whose frequencies increase significantly from one class to another. They have been proven useful to build powerful classifiers ...

Constraint Relaxations for Discovering Unknown Sequential Patterns
The main drawbacks of sequential pattern mining have been its lack of focus on user expectations and the high number of discovered patterns. However, the solution commonly accepted...
