KNIME Model Queries

[Matthias_CTS]

Hello KNIME community.

Hoping for some advice, I’m trying to predict TargetBuy (Organics Purchase Indicator)

1. I’m wondering why my accuracy is 100% for all models?
2. Also, must all data be converted to a string to process?
3. Any way to be more efficient in this? i.e using other nodes

Hi @Matthias_CTS and welcome to the forum.

In this case it looks like this happens because you have included the field Organics Purchase Count as a feature. If you remove it, your results look a lot more reasonable.

EDIT: By the way, one way to intuit this is to look at the view of the decision tree. There you can see that the model is taking only a single predictor into account to arrive at 100% accuracy.
