Data analysis (affinity analysis or data mining) includes computational techniques for discovering relationships of data that come from activities performed by specific individuals or groups. Generally, data analysis can be applied to any data. In DSPLab, data analysis is used to perform market basket analysis, in which retailers seek to understand the purchase behavior of customers. Which items with which brand mark purchase together is one of the questions we want to seek answers for. Our research objective is to introduce new and effective approach to obtain this answer.
