Methods for identifying partial periodic patterns of infrequent events in an event sequences
A method is provided for mining partial periodic patterns in an event sequence, wherein each pattern includes a list of events from the event sequence. At least one subsequence of the event sequence and at least one pattern in the at least one subsequence are identified, such that an information gain of the at least one subsequence with respect to the at least one pattern exceeds a predefined threshold. At least one of the at least one pattern and the at least one subsequence is stored.
