Partial Dependence Plot (PDP) The partial dependence plot (short PDP or PD plot) shows the marginal effect one or two features have on the predicted outcome of a machine learning model (J. H. Friedman 2001 30 ). A partial dependence plot can show whether the relationship between the target and a feature is linear, monotonic or more complex.
