- Abstract: For artificial intelligence, high-utility sequential rule mining (HUSRM) is a
knowledge discovery method that can reveal the associations between events in
the sequences. Recently, abundant methods have been proposed to discover
high-utility sequence rules. However, the existing methods are all related to
point-based sequences. Interval events that persist for some time are common.
Traditional interval-event sequence knowledge discovery tasks mainly focus on
pattern discovery, but patterns cannot reveal the correlation between interval
events well. Moreover, the existing HUSRM algorithms cannot be directly applied
to interval-event sequences since the relation in interval-event sequences is
much more intricate than those in point-based sequences. In this work, we
propose a utility-driven interval rule mining (UIRMiner) algorithm that can
extract all utility-driven interval rules (UIRs) from the interval-event
sequence database to solve the problem. In UIRMiner, we first introduce a
numeric encoding relation representation, which can save much time on relation
computation and storage on relation representation. Furthermore, to shrink the
search space, we also propose a complement pruning strategy, which incorporates
the utility upper bound with the relation. Finally, plentiful experiments
implemented on both real-world and synthetic datasets verify that UIRMiner is
an effective and efficient algorithm.

High-utility sequential rule mining (HUSRM) is designed to explore the confidence or probability of predicting the occurrence of consequence sequential patterns.
The existing algorithm, known as HUSRM, is limited to extracting all eligible rules while neglecting the correlation between the generated sequential rules.
We propose a novel algorithm called correlated high-utility sequential rule miner (CoUSR) to integrate the concept of correlation into HUSRM.

We propose two novel algorithms, called TotalSR and TotalSR+, which aim to identify all high utility totally-ordered sequential rules (HTSRs)
TotalSR creates a utility table that can efficiently calculate antecedent support and a utility prefix sum list that can compute the remaining utility in O(1) time for a sequence.
There are numerous experimental results on both real and synthetic datasets demonstrating that TotalSR is significantly more efficient than algorithms with fewer pruning strategies.
