Introduction
An important application areaMarket basket analysisThe difficulty of data stream applications
An example of online transaction flows
A Regression-Based Algo.
FTP-DSTwo major featuresOne data scan for online statistics collectionRegression-based compact pattern representation
One scan for online statistics collection
Generation of frequent temporal itemsets (MinSup = 0.4)
Regression-based Analysis
The analysis is employed to capture the trends of frequent patternsLinear function
Conforming to the least squares
The time series of averaged support for the inter-transaction itemset (c,g)
ATF Form
Def :
PurposeTo compact the data when we track the frequency variations
The fit line of regression analysis
