Latest Patents
Yongjin Ma holds a patent for an "Analytic system for machine learning prediction model selection." This patent describes a sophisticated method for selecting an assessment dataset from an input dataset using a first stratified sampling process based on the value of an event assessment variable. The remaining input dataset is then allocated to a training/validation dataset, which is further partitioned into an oversampled training/validation dataset. This process utilizes an oversampling technique based on a predefined value of the event assessment variable. The validation sample is selected from this oversampled dataset using a second stratified sampling process, ensuring that the training and validation samples are mutually exclusive. Ultimately, a predictive type model is trained using the selected training sample, and multiple predictive models are trained, validated, and scored to identify the best predictive model.
