Advance Mining of Temporal High Utility Itemset
ABSTRACT
The stock market domain is a dynamic and unpredictable environment. Traditional techniques,
such as fundamental and technical analysis can provide investors with some tools for managing
their stocks and predicting their prices. However, these techniques cannot discover all the
possible relations between stocks and thus there is a need for a different approach that will
provide a deeper kind of analysis. Data mining can be used extensively in the financial markets
and help in stock-price forecasting. Therefore, we propose in this paper a portfolio management
solution with business intelligence characteristics. We know that the temporal high utility
itemsets are the itemsets with support larger than a pre-specified threshold in current time
window of data stream. Discovery of temporal high utility itemsets is an important process for
mining interesting patterns like association rules from data streams. We proposed the novel
algorithm for temporal association mining with utility approach. This make us to find the
temporal high utility itemset which can generate less candidate itemsets.
EXISTING SYSTEM
The rationale behind mining frequent itemsets is that only itemsets with high frequency
are of interest to users. However, the practical usefulness of frequent itemsets is limited by the
significance of the discovered itemsets. A frequent itemset only reflects the statistical correlation
between items, and it does not reflect the semantic significance of the items. In this paper, we
propose a utility based itemsetmining approach to overcome this limitation.
PROPOSED SYSTEM
The rationale behind mining frequent itemsets is that only itemsets with high frequency
are of interest to users. However, the practical usefulness of frequent itemsets is limited by the
significance of the discovered itemsets. A frequent itemset only reflects the statistical correlation
between items, and it does not reflect the semantic significance of the items. In this paper, we
propose a utility based itemsetmining approach to overcome this limitation. The proposed
approach permits users to quantify their preferences concerning the usefulness of itemsets using
utility values. The usefulness of an itemset is characterized as a utility constraint. That is, an
itemset is interesting to the user only if it satisfies a given utility constraint. We show that the
pruning strategies used in previous itemsetmining approaches cannot be applied to utility
constraints. In response, we identify several mathematical properties of utility constraints. Then,
two novel pruning strategies are designed. Two algorithms for utility based itemsetmining are
developed by incorporating these pruning strategies. The algorithms are evaluated by applying
them to synthetic and real world databases. Experimental results show that the proposed
algorithms are effective on the databases tested.
