Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer-readable medium having stored thereon instructions that are executable by a computer system to cause the computer system to perform operations comprising:
accessing a machine learning classifier comprising a plurality of decision trees, wherein the machine learning classifier was built using transaction data for a plurality of transactions, each of the plurality of transactions having a plurality of associated feature values for a feature space comprising a plurality of features;
for each of one or more candidate trees of the plurality of decision trees, evaluating a plurality of branch paths in that candidate tree fora transaction classification performance using a set of evaluation transaction data;
based on the evaluating, identifying one or more candidate transaction classification rules;
automatically editing, without human intervention, at least a particular candidate transaction classification rule of the or more candidate transaction classification rules by changing at least one feature value in the particular candidate transaction classification rule, wherein the automatically editing comprises reducing a number of digits of the at least one feature value;
evaluating a transaction classification performance of the edited particular candidate transaction classification rule;
determining, based on a set of criteria and a result of the evaluating, whether the edited particular candidate transaction classification rule can be further edited; and
further editing, based on a determination that the edited particular candidate transaction classification rule can be further edited, the particular candidate transaction classification rule at least in part by further reducing the number of digits of the at least one feature value.
