Big Data thinking - What makes Big Data different?

Merely calculating faster or storing more should not qualify for a Big Data thinking. It is purely technological breakthrough - just like having a faster CPU. Will you call an intel CPU i7 a change of era from i5? Here are my observations and principles to be Big Data:

novel itemset representations based on prefix-tree nodes for frequent itemset mining

In recent years, I proposed three new kinds of data structure to represent itemsets. They are Node-list [1], N-list [2], and Nodeset [3]. They use prefix-tree nodes to represent itemsets instead of the set of tranaction ids.

Since prefix-tree is usually high compressed, Node-list [1], N-list [2], and Nodeset [3] are much shorten than Tidset or diffset, which are two classical vertical representatnion of itemsets. Therefore, for frequent itemset mining, the algorithms based on Node-list,…

Anemic Adoption still ailing BI

Here is an excerpt from a TDWI article - "The Year in BI and Data Warehousing" - that was published in December 2013.

"One of the things that ailed BI in 1993 and 2003 is the same thing that ails BI today: i.e., anemic adoption. This is in spite of the fact that today's BI tools incorporate a staggering array of "self-service" features, along with (often…
