Abstract: Predictive models have always been sought in the physical, biological and social sciences, but the application of such models may not produce reliable results. Before accepting a prediction from any model, it is essential to ascertain that the model is applicable to make the prediction. The present invention generally relates to a method for validating a model based prediction and more specifically, to a method for validating whether selected models are applicable to selected queries and comparing the performance of the predictive model on a query object or point, etc., with the performance of the predictive model on an existing object having a shortest property sensitive similarity index from the query object or point, etc. in a data processing system.
