One is the performance of data mining algorithms degrades, the other is many distance - based and density - based algorithms maybe not effective. these problems can be solved by the following methods : l ) transport the data from high dimensional space to lower dimensional space by dimensionality reduction, then process the data as lower dimensional data. 2 ) to improve the performance of mining algorithms, we can design more effective indexing structures, adopt incremental algorithms and parallel algorithms and so on
解決的方法可以有以下幾種：一個可以通過降維將數據從高維降到低維，然後用低維數據的處理辦法進行處理；對演算法效率下降問題可以通過設計更為有效的索引結構、採用增量演算法及并行演算法等來提高演算法的性能；對失效的問題通過重新定義使其獲得新生。
