Questions and Answers

What is ALE used for?

To calculate the effect of a prediction on the feature

To calculate the effect of a feature on the prediction (correct)

To calculate the effect of a label on the feature

To calculate the effect of a feature on the model's accuracy

What is the interpretation of ALE?

The difference in prediction for each interval

The main effect of the feature compared to the average prediction (correct)

The average of the lines of an ICE plot

The linear relationship between features and prediction

What is the difference between ICE plots and PDPs?

ICE plots visualize the dependence of the prediction on a feature for each instance separately

ICE plots create variants of an instance by replacing the feature's value with values from a grid

ICE plots show one line per instance compared to one line overall in PDPs (correct)

PDPs are the average of the lines of an ICE plot

Study Notes

ALE is used to calculate the effect of a feature on the prediction.
The feature is divided into intervals and the difference in prediction is calculated for each interval.
The differences are accumulated and centered to create the ALE curve.
ALE can be interpreted as the main effect of the feature compared to the average prediction.
ALE correctly identifies linear relationships between features and prediction.
ICE plots visualize the dependence of the prediction on a feature for each instance separately.
ICE plots show one line per instance compared to one line overall in PDPs.
PDPs are the average of the lines of an ICE plot.
ICE plots create variants of an instance by replacing the feature's value with values from a grid.
ICE plots make predictions with the black box model for the newly created instances.
