Abstract

A method of predicting consumer response to given content. The process begins with the step of collecting a dataset of consumer response to the content, each data item including values for a selected set of segmentation variables related to past consumer behavior. The dataset contains at least twice the number of entries required to provide statistical validity. The process continues by constructing a classification tree structure using the dataset, in which the dataset is subdivided into learning and validation datasets of substantially equal size. Also, the criterion for each successive split is the lowest entropy of segmentation variables not employed to the point of such split. Each successive split of the learning dataset is performed only if that split produces child nodes statistically different from one another, and an identical split of the validation data set produces child nodes statistically similar to child nodes produced on the learning dataset. The system estimates consumer responses by first receiving a data item related to a new consumer, including values for the segmentation variables and then computing the likely response of the new consumer to the content, employing the classification tree data structure.
