One is that the algorithm breaks traditional thinking of generating candidate frequent itemsets, namely, it generates candidate frequent itemsets by updating the mixed radix numeral.

For discovering frequent spatiotemporal association patterns, it only needs to read the database once; and then it generates candidate frequent itemsets via updating the mixed radix numeral, where granular computing is introduced to save reading the spatiotemporal database.
5 A mixed radix notation system based on a spatiotemporal information system is a triple M= {STIS, m, < [w.
m, called the number of bit for the mixed radix notation system, is denoted by m = [absolute value of A] ;
m] >, called the weight set of bit for the mixed radix notation system, each element [w.
For example, for the spatiotemporal information system of table 1, we can get the following mixed radix notation system based on a spatiotemporal information system M = {STIS, 10, < 3, 3, 4, 4, 4, 9, 8, 8, 8, 8>}.
1])M ; //a decimal integer i is turned into a mixed radix numeral [([[omega].
In other word, the algorithm updates the mixed radix numeral to generate candidate frequent itemsets.
However, the algorithm DFSTAP updates the mixed radix numeral to generate candidates; the speed of which for the latter is faster than the former; additionally, the DFSTAP only needs to read the database once.

In large scale search and database applications, Quantized Indexing provides unique advantages over alternative compression methods in coding bitmap indices, mixed radix codes, such as permutations, and other search metadata which are encountered in large data bases and data warehouses.
