Identifying High-vote Patterns
- 94 Downloads
While traditional multi-database mining algorithms focus on identifying mono-database-mining-like patterns, in this chapter we develop techniques for identifying novel patterns (high-vote patterns) in multi-databases by analyzing local patterns. The number of patterns forwarded from, say, company branches, may be so large that browsing the pattern set, and finding interesting patterns from it, could be rather difficult for a head office. In particular, it is more difficult to identify which of the forwarded patterns are really useful for a company’s applications. In this chapter we design efficient strategies to search for high-vote patterns from local patterns within the branches of a company. As we stated in Chapter 1, this approach is particularly useful in dual-level applications. Another technique we develop provides a good human interface, by constructing a fuzzy logic controller.
