Measuring classifier performance is important in machine learning. Risk charts and error matrix charts have been developed for this purpose. The strengths and weak-nesses of using these charts are outlined. Challenges with using these charts are dis-cussed including how base rates and using prevalence data for building models and incidence data for evaluating models affect model performance. A number of solu-tions for overcoming these challenges are covered.
