An Efficient Tree-Based Algorithm for Mining High Average-Utility Itemset
High-utility itemset mining (HUIM), which is an extension of well-known frequent itemset mining (FIM), has become a key topic in recent years. HUIM aims to find a complete set of itemsets having high utilities in a given dataset.

Index Maintenance Strategy and Cost Model for Extended Cluster Pruning [PDF]
With today’s dynamic multimedia collections, maintenance of high-dimensional indexes is an important, yet understudied topic. Extended Cluster Pruning (eCP) is a highly-scalable approximate indexing approach based on clustering, that is targeted at ...

EHAUPM: Efficient High Average-Utility Pattern Mining With Tighter Upper Bounds
High-utility itemset mining (HUIM) has become a popular data mining task, as it can reveal patterns that have a high-utility, contrarily to frequent pattern mining, which focuses on discovering frequent patterns.

An Efficient Adjoint Pattern Mining Algorithm for Moving Object [PDF]
Mining adjoint patterns of moving objects is finding the set of objects with similar trajectories and time from a spatio-temporal perspective,which is widely used in user behavior analysis based on geographical location.However,the existing similarity ...

Bonsai trees in your head: how the pavlovian system sculpts goal-directed choices by pruning decision trees. [PDF]
When planning a series of actions, it is usually infeasible to consider all potential future sequences; instead, one must prune the decision tree. Provably optimal pruning is, however, still computationally ruinous and the specific approximations humans ...

TUB-HAUPM: Tighter Upper Bound for Mining High Average-Utility Patterns
High-utility itemset mining (HUIM) has been gaining popularity in the field of data mining. Frequent itemset mining used to be the main tool to reveal high-frequency patterns but failed to consider the concept of profit.
