Frequency-based Constrained Sampling for Interval Patterns
Researchers have developed a new sampling approach called CFips for exploring large pattern spaces, specifically focusing on interval patterns with user-defined constraints. This method integrates constraints directly into the sampling procedure, decomposing them into elementary predicates on interval bounds to ensure exact sampling guarantees. Experimental results indicate that CFips can successfully complete mining tasks that might otherwise fail due to time constraints. AI
