| Abstract: | The basic philosophy and the performance analysis of algorithms mining relevance rules are introduced . The obvious shortcoming of FP-tree algorithm in knowledge discovery is analysised. A frequent Pattern tree growth algorithm based on improved projection is presented to improve construction of FP-tree in mining relevance rules. The effectiveness of the method proposed here is demonstrated by an illustration simulation. |
