Many algorithms came into existence for mining association rules.Since the databases in the real world are subjected to frequent changes, the algorithms need to be rerun to generate association rules that can reflect record insertions.Abstract: This paper proposes a new data stream outlier detection algorithm SODRNN based on reverse nearest neighbors.We deal with the sliding window model, where outlier queries are performed in order to detect anomalies in the current window.Experiments results on synthetic datasets show that our proposed algorithm is both time and space efficient.uses cookies to personalize content, tailor ads and improve the user experience.

Abstract: Online mining of frequent closed itemsets over streaming data is one of the most important issues in mining data streams.

This paper focuses on mining maximal frequent itemsets approximately over a stream landmark model.

A false negative method is proposed based on Chernoff Bound to save the computing and memory cost.
