The explosive growth of the insurance data puts forward a higher demand for the data processing of the internet of things. This paper adopts distributed database as the underlying data storage, combines with array-based apriori technology on the basis of data mining, applies and queries, and proposes a type of array-based apriori optimization algorithm. Array-based data layout, first stacks data arrays,...
Microarray image gridding is one important step of microarray image analysis to determine 2D image coordinates of all array spots in the hybridized gene chip image. Accuracy of microarray image gridding will affect the reliability of gene-chip data extraction and even the final analysis results of gene-chip assays. However, in recent years, many new microarray image gridding methods presented have...
A mining top-n frequent closed itemsets of length no less than min_l algorithm is introduced by this paper, where n is the desired number of frequent closed itemsets to be mined, and min_l is the minimal length of each itemset. An efficient algorithm, called TFP, is developed for mining such itemsets without mins_support. Starting at min_support=0 and by making use of the length constraint and the...
