Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
accessing, by a computer system, 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, the computer system evaluating a plurality of branch paths in that candidate tree for a transaction classification performance using a set of evaluation transaction data;
based on the evaluating, the computer system identifying one or more candidate transaction classification rules;
automatically without human intervention, editing a particular candidate transaction classification rule of the one or more candidate transaction classification rules, wherein the editing comprises reducing a number of digits of a numeric feature value included in the particular candidate transaction classification rule;
comparing a transaction classification performance of the edited particular candidate transaction classification rule against a specified threshold; and
further editing, based on the comparing, the particular candidate transaction classification rule at least in part by further reducing the number of digits of the numeric feature value.
