Although it was considered impossible to compute the eigenvector of a very large scale of Web graph using previous techniques, due to this calculation requires enormous memory sp

This new kind of rule, ordinal association rules, reveals the overall behavior of the population and it is vital that this study

In C4.5, all attributes, barring the nominal attributes used at the parent nodes, are retained for further computation. This leads to extra overheads of

According to our observation on real data, the distribution of attributes with respect to information gain is very sparse because only a few attributes are major discriminating attributes where a discriminating attribute is an attribute, by whose value we are likely to distinguish

Lecture Notes in Computer ScienceThe prospects of XML for data warehousing are staggering. As a primary purpose of data warehouses is to store non-operational data in the long term, i.e., to . them over time, the key reasons for the overwhelming success of XML as an . format also hold for data warehouses.
