Classification: CPC G | IPC G

Claim 10:
11. A system, comprising:
a processor; and
a memory having stored thereon instructions that are executable by the processor to cause the system to perform operations comprising:
building a machine learning classifier comprising a plurality of decision trees, wherein the machine learning classifier is 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 for a transaction classification performance using a set of evaluation transaction data;
based on the evaluating, identifying one or more candidate transaction classification rules;
automatically editing a first 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 first candidate transaction classification rule;
evaluating a transaction classification performance of the edited first candidate transaction classification rule;
determining, based on a result of the evaluating, that the edited first candidate transaction classification rule can be further edited; and
further reducing, based on the determining, the number of digits of the numeric feature value.
