In this work, we present an aggregate retargeting mechanism that deals with multiple fact table schemas (MFTS), which are composed of many fact tables related by conformed dimens

The target query workload consists of all base and aggregate cells that are stored in a multidimensional array (i.e. cube). These queries are actually range queries pre-defined by users.

The inductive databases are databases with a tight integration to data mining facilities. However, it is no

The approach is based on heuristic search through the space of polynomial equations and can use subsumption and evaluation constraints on polynomial equations. We evaluate this approach on standard regression problems. We finally consider IDB

From Temporal Rules to Temporal Meta-rulesframework is based on first-order temporal logic and allows the definition of the main temporal data mining notions (event, temporal rule, constraint) in a formal way. The concepts of . and . are fundamentals in the design of algorithms for inferring higher order temporal rules, (called .), from local sets of temporal rules.
