Rule Engine with Machine Learning, Deep Learning, Neural NetworkRule Engine and Machine Learning are often viewed as competing technology. But this view is not correct. Rule Engine and Machine Learning can be incorporated together to become a very powerful platform. For example, Deep Learing refers structured multiple neural network models. Rule Engine can be used to glue multiple neural networks to work as a single powerful model seamlessly, thus implementing structured neural networks which are Deep Learning Models. RMEEP (Rulebased Model Evaluation with Event Processing) is a very powerful expert system shell rule engine, incorporating predictive modeling by machine learning algorithms, such as neural network, self organizing maps, decision tree, regression, time series, statistical functions, and so on. It combines rule based "forwardinference" reasoning with predictive modeling by machine learning. It provides a powerful platform for structured Deep Learning. SQLlike Rules for Business usersRMEEP has been developed to use SQLlike expressions 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. Note that SQL users can learn RMEEP very quickly! The 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 Modeling by Machine Learning for Deep LearningThe core concept of RMEEP is Rulebased (Predictive) Model Evaluation. RMEEP incorporates predictive models with many logical and mathematical functions of SQL99. By incorporating advanced predictive models into rule engine, RMEEP provides a superb platform for advanced rulebased expert systems and deep learning. RMEEP supports the following machine learning based predictive models;
(Example) Deep Learning Risk Modeling by Rule Engine and Machine LearningThe following is a RMEEP Deep Learning style example for risk scoring. This is an extension of predictive modeling by machine learning described in the following links;
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 and 10. Viz;
It is noted that this model incorporates neural network, decision tree and regression as a single RMEEP model. It is a decision support expert system on a model. The following is a screenshot of of this deep learning model output on MyDataSay Android Application. MyDataSay download has this model. You can download from the link. Note that RMEEP is a feature of CMSR Data Miner / Machine Learning Studio, you can download and try this model with CMSR Data Miner / Machine Learning / Rule Engine Studio. Downloads contain more advanced sample models.
