RMEEP – Expert System Shell with Predictive Modeling and Deep LearningRMEEP (Rulebased Model Evaluation  Event Processing) is a very powerful expert system shell supporting predictive modeling such as neural network, self organizing maps, decision tree, regression, time series, etc. It combines rule based reasoning with predictive modeling, providing a platform for Deep Learning methods. RMEEP has been developed to use SQLlike language which can be learnt by business users and domain experts very easily and quickly. NonIT professional users can write RMEEP expert system rules by themselves without IT professional help. RMEEP opens a new era for business users and domain experts. SQLlike Business Rules for Business usersThe popularity of SQL as the preferred database query language has been largely due to the natural intuitiveness of the language as well as the richness of logical expressions. SQL is very easy to learn. Expressions written in SQL is very easy to understand and hence has been widely used by many nonIT professional such as business analysts and users, as well as by IT professionals. RMEEP is based on SQL99 syntax supporting most logical and arithmetic language features. Predictive ModelingThe core concept of RMEEP is Rulebased Predictive Model Evaluation. RMEEP incorporates predictive models with many logical and mathematical functions of SQL99 as patterns. By incorporating advanced predictive models into rule engine, RMEEP provides a superb platform for advanced rulebased expert systems. RMEEP supports the following predictive models;
Deep Learning Style Risk Modeling ExampleThe following is a RMEEP example for risk scoring, a la Deep Learning style. Note that this uses five neural network models: Model1, Model2, Model3, Model5 and Model6. In addition, it also uses a decision tree model Model4. Model1, 2, 3 and 4 evaluate input data. Model5 and 6 are used to integerate results of Model1 ~ 4. In the begining, variables are declared. Rule 1, 2, 3 and 4 evaluate first four models and store on variables "Model1 score", "Model2 score", "Model3 score" and "Model4 score", respectively. Rule 5, then, computes maximum, minimum and average values of these three models. Rule 6 and 7 evaluate second tier integration models "Model5" and "Model6", using four model output values, maximum, minimum and average values. Final result scores will be stored on "Final score1" and "Final score2". Then average of these final value is computed by Rule 8. Based on "Final average" and Max/Min/Avg values, risk levels are verbalized by Rule 9. Viz;
