Determining Coefficient Weights in a Rational Quadratic GPR model

2 views (last 30 days)
Hello there I have a trianed GPR model stored in the workspace as "GPRModel". I have 63 input featured for my trianed model and I am trying to detmine which features are weighted the highest and contribute the most to the model's predictions. My training data with the features is stored in a Table named: "AllFinalTrials". Let me know if there is any way to determine the coefficents or wieghts of the featured for this Rational Quadratic GPR model. Thank you so much!

If you want to know "which features ... contribute the most to the model's predictions", one way to do that is to use model interpretability techniques. Here are a couple of interpretability techniques that can produce an importance value for each feature of your Rational Quadratic GPR model:
