Generate Transaction Data

Synopsis​

This operator generates an ExampleSet that represents transaction data. The number of transactions, number of customers, number of items and number of clusters can be specified by the user.

Description​

The Generate Transaction Data operator generates an ExampleSet representing transaction data. This ExampleSet can be used when you do not have a data set that represents a real transaction data. It can also be used as a placeholder for such a requirement. This data set has 2 regular attributes and 1 special attribute. The regular attributes are Item (nominal) and Amount (integer). The special attribute is Id (nominal). This Id attribute represents the customer Id. All items purchased by a single customer are listed in form of multiple examples with the same customer Id. The Item attribute tells which item was purchased and the Amount attribute tells the quantity of the item that was purchased. The number of transactions can be set by the number transactions parameter. To have a look at this ExampleSet, just run the attached Example Process.

Number items​

This parameter specifies the number of generated items.

Number clusters​

This parameter specifies the number of generated clusters.

Use local random seed​

This parameter indicates if a local random seed should be used for randomization. Using the same value of local random seed will produce the same ExampleSet. Changing the value of this parameter changes the way examples are randomized, thus the ExampleSet will have a different set of values.

Local random seed​

This parameter specifies the local random seed. This parameter is only available if the use local random seed parameter is set to true.
