Abstract

Performance advertisers want to maximize the return on their advertising spend. In the online advertising world, this means showing the ad only to those users most likely to convert i.e. buy a product or service. Existing ad targeting solutions such as context targeting and rule-based segment targeting primarily leverage marketing intuition to identify audience segments that would be likely to convert. Even the more sophisticated model-based approaches such as behavioral targeting identify audience segments interested in certain coarse-grained categories defined by the publisher. Advertisers are now able, through beaconing, to tell us exactly who their preferred customers are. Advertisers want to augment their existing advertising campaign with custom models that learn from the campaign and focus on attracting new users. Motivated by our experience with advertisers, we pose this problem within the context of ensemble learning. Building custom models for an existing ad campaign can be viewed as operations on an ensemble classifier: add, modify, or complement a classifier. An ideal new classifier should incrementally improve the ensemble and minimize overlap with any existing classifiers already in the ensemble–it should learn something new. With the proposed approach we are able to augment the advertising campaigns of several large advertisers at a large online advertising company.
