15.35. Inputs Correlated with Target

Applies to: NeuralTools 5.x–7.x

Some of my training reports showed surprisingly low association with inputs which were quite visibly correlated with the target itself. Is there a way to bias the training to take advantage of this?

This refers to the Variable Impact values that are included in training reports. It's important to understand the purpose of the Impact values, and how they're calculated. Calculation and Use of Variable Impacts has a lot to say about this.

The purpose is only heuristic, and the idea is that it's worth dropping variables with low impact values to see if the results improve.
