Apriori-Visualization

This is a program to visualize the Apriori Algorithm developed within Processing (processing.org). Its source code contains these files:

JsonTest.pde -- the main file to run with the following parameters to modify

widthW -- window width

heightW -- window height

Node.pde -- Node class

Spring.pde -- Spring class which connects two nodes

./data/test.json -- the node information to read during the algorithm. It is a JSON format with the following structure:

minSupport -- minimum support threshold

numNodes -- total number of nodes include those need to be pruned

Node

  Name -- name of items, e.g. {1 2 3}
  
  ID -- ID of the node, which unique with its depth and index, e.g. {0 1}
  
  frequency -- frequency of the node, if it is pruned with absence of subset in parent layer, frequency = -1
  
  parentID -- parentID
