Incremental Emerging Patterns Mining for Identifying Safe and Non-safe Power Load Lines

In this paper, we proposed an incremental TFP-tree algorithm for mining emerging patterns that can search efficiently within limitation of memory. Especially, the concept of pre-infrequent patterns pruning and use of two different minimum supports, it made the algorithm be possible to mine most emerging patterns and handle the problem of mining from incrementally increased, large size of data sets. We also defined and analyzed the significant difference of safe and non-safe power load lines and identify which line is potentially non-safe by using those emerging patterns.
