Convert Attributes to be binominal

domi_wiese

Hello,

I've got a question about converting Attributes to be binominal.

I'm using the ,,Direct Mailing Data Set" and have tried to convert these attributes to be binominal by using the operator ,,nominal to binominal". But my performance operator for binominal classification always responds ,, Cannot evaluate labels of type nominal".

The thing is, the whole process works, but without the performance operator.

I'm very confused.

I'm would be very thankful if someone could help me please.

This has been discussed recently (checkthis link).

If the label variable only has two categories you can use "Binomial Classification Performance" without any problem. It will give you a warning but it will work as expected.

Check this process:

The model created in the Training step is applied to the current test set (10 %).<br/>The performance is evaluated and sent to the operator results.
