Clusterering items in different data sources induced by stability

الملخص EN

Many multi-breach companies transact from different branches.

Each a company maintains a separate database over time.

The variation of sales of an item over is an important issue.

Thus, we introduce the notion of stability of an item.

Stable items are useful in making many strategic decisions for a company.

Based the degree of stability of an item, we design an algorithm for clustering items in different data sources.

We have proposed the notion of best cluster by considering average of variation of a class.

Also, we have designed an alternative algorithm to find best cluster among items in different data sources.

Experimental results are provided on three transactional data based.
