Issue from Scorer and X aggregator

[Xin_12]

hi, here’s part of my workflow, and the node setup from both x aggregator and scorer, my first question: 1. all the target and prediction column are bound to String type in the x aggregator node. But as I want to select “reference column” according to my target in x aggregator and the predicted column according to the prediction column in x aggregator, they both can’t show up, because in the scorer, they only appear “double type”. (The K-ai said it should have string type, but none…) how can i select…? 2.may i ask if just “reference column, predicted column and number of prediction” should be selected or answered, while others remain untouched? Big thanks

Hi @Xin_12,

The Numeric Scorer node is mainly used for regression models, where the target variable is numeric. If your target is a string or categorical class, you should use the Scorer node instead:
