Select actionable positive or negative sequential patterns
Negative sequential patterns (NSP) refer to sequences with non-occurring and occurring items, and can play an irreplaceable role in understanding and addressing many business applications. However, some problems occur after mining NSP, the most urgent one of which is how to select the actionable positive or negative sequential patterns. This is due to the following factors: 1) positive sequenti...
متن کاملMining Strong Positive and Negative Sequential Patterns
In data mining field, sequential pattern mining can be applied in divers applications such as basket analysis, web access patterns analysis, and quality control in manufactory engineering, etc. Many methods have been proposed for mining sequential patterns. However, conventional methods only consider the occurrences of itemsets in customer sequences. The sequential patterns discovered by these ...
متن کاملMining Negative Sequential Patterns
Sequential pattern mining is to discover all frequent sequences from a sequence database and has been an important issue in data mining. A lot of methods have been proposed for mining sequential pattern. However, conventional methods consider only the occurrences of itemsets in a sequence database, and the sequential patterns are referred to as positive sequential patterns. In practice, the abs...
متن کاملMining Negative Fuzzy Sequential Patterns
Many methods have been proposed for mining fuzzy sequential patterns. However, most of conventional methods only consider the occurrences of fuzzy itemsets in sequences. The fuzzy sequential patterns discovered by these methods are called as positive fuzzy sequential patterns. In practice, the absences of frequent fuzzy itemsets in sequences may imply significant information. We call a fuzzy se...
متن کاملMining Actionable Patterns
We propose a generic framework that uses utility in decision making to drive the data mining process. We use concepts from meta-learning and build on earlier work by Elovici and Braha, that uses decision theory for formulating an utility measure, to specialize the framework for classification tasks. We show empirical validation of the approach on a simple test domain.
