Patent number: 11423324Abstract: A training method is provided. The training method includes clustering, by a processor, a plurality of items that each have an item attribute value, according to the item attribute value. The training method further includes generating, by the processor, for each item, a cluster attribute value corresponding to a cluster associated with the item. The training method also includes training, by the processor, an estimation model for estimating selection behavior of a target with respect to a choice set including two or more items, based on the cluster attribute value associated with each item included in the choice set, by using training data that includes a group of a choice set of items presented to the target and an item selected by the target from among the choice set.Type: GrantFiled: February 23, 2017Date of Patent: August 23, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Tetsuro Morimura, Yachiko Obara, Takayuki Osogami
