Latest Patents

Xiaotong Chen holds a patent titled "Generating rule lists from tree ensemble models." This patent describes systems and methods for extracting rule lists from tree ensembles. The system extracts first stage candidate rules from individual trees and identifies those that satisfy a precision threshold, placing them in a solution set. A determination is then made whether a further stage is needed based on the coverage of positive data samples by the solution set. In the further stage, the system generates next stage candidate rules from previous stage candidate rules that have not been pruned. It identifies the next stage candidate rules that meet the precision threshold and places them in the solution set. Ultimately, a simplified rule list is generated by identifying a minimum subset of rules that covers the positive data samples within the precision threshold.
