03_Bioactivity_Prediction_Learn_Testing

This workflow is used for learning the model. It deploys a simple version of parameter optimzation protocol designed for testing the Model Factory system. In this version two machine learning methods are used and parameter optimization is performed twice. For the full version see workflow 03_Bioactivity_Prediction_Learn_All_Methods.
