Classification: CPC G | IPC G

Claim 8:
9. A system comprising:
one or more processors; and
a memory storing instructions that, when executed by at least one processor among the one or more processors, cause the system to perform operations comprising:
accessing a training database of reference metadata descriptive of reference travel plans that include reference first-type travel plans and reference second-type travel plans;
training a learning machine to distinguish candidate first-type travel plans from candidate second-type travel plans, the candidate first-type travel plans comprising non-reimbursable non-business travel plans, the candidate second-type travel plans comprising reimbursable business travel plans, the learning machine being trained based on decision trees generated from randomly selected subsets of the reference metadata that is descriptive of the reference travel plans, the randomly selected subsets each describing a corresponding randomly selected portion of the reference travel plans that include the reference first-type travel plans and the reference second-type travel plans;
modifying the trained learning machine based on asymmetrical penalties for incorrectly distinguishing candidate first-type travel plans from candidate second-type travel plans, the asymmetrical penalties including unequal first and second penalties, the first penalty to be applied for incorrectly classifying a candidate first-type travel plan being greater than the second penalty to be applied for incorrectly classifying a candidate second-type travel plan; and
providing the modified learning machine trained to distinguish candidate first-type travel plans from candidate second-type travel plans based on the asymmetrical penalties for incorrectly distinguishing candidate first-type travel plans from candidate second-type travel plans.
