Paper Abstract:
|
Despite the advances of Machine Learning (ML), the models are still being considered black-boxes that are difficult to
explain. In order to address the need to interpret the ML models, I suggest the novel Input Prediction Association (IPA)
plots which are based on the means of inputs and predictions, calculated in the models prediction ranks. The resulting plots
provide a model-agnostic method of visualizing associations between the inputs and predictions. The IPA plots can help
detect inputs that are linearly correlated with predictions as well as help identify the pattern of their relationships. The IPA
plots can also be used to establish inputs thresholds that correspond to high predicted probabilities for the event of interest,
thus extending the interpretation of the model inputs to an individual observation level. Such an approach can be applied
in Customer Relationship Management since it suggests not only who to target but also it provides insights as to why to
target specific individuals.We illustrate the IPA approach with an example from the field of home equity loan risk analysis
in banking. |
