This node classifies each trace variant from the event log according to the given label and its distribution. Trace variant is a set of traces which have the same event classes sequence. The following inputs are required: a given label, a list of possible values and their corresponding distributions. The sum of distributions are 1.0. Otherwise, it gives one configuration exception.
For example, to classify one event log by attribute "kpi" with the following distribution, {"pos", 0.5} and {"neg", 0.5}. The configuration steps are :

1. Given the Label Name "kpi" at the top of the table;
2. Click the button "Add label value" to add value for this label and its percent.
3. Input value "pos" to Label values and 0.5 to Label value percentages.
4. Input value "neg" to Label values and 0.5 to Label value percentages.

After execution, given 10 traces for 2 trace variants in the event log, then for each trace variant, 5 traces are assigned with "pos" for label "kpi", 5 traces are assigned as "neg". If the sum doesn't match the total trace number, the one with the highest percent will be assigned to the difference value.

Options

Label Name

The category name for classification

Label Values

The possible label value.

Label Value Percentage

The percentage of corresponding label value for one trace variant. The value is between 0 - 1.0. The sum of the all percentage values should be 1.
