The method disclosed herein includes preprocessing large amounts of input data into a smaller input data sets based on first predetermined associations, sorting the smaller input data sets into groups based on second predetermined associations, filtering grouped data based on upper and lower thresholds, updating a hierarchical processing decision tree within a processor of a computing system, processing data based on the updated hierarchical processing decision tree, and recursively restarting the preprocessing of the large amounts of input data to dynamically update the hierarchical processing decision tree within a user device.
