Estimating age using multiple classifiers

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing age estimation. In one aspect, a method includes receiving an image of a person, submitting the image to multiple binary classifiers that are each trained to classify the person in the image as belonging to one of two predefined age groups, or as belonging or not belonging to a particular age group, where each output includes a confidence value associated with classifying the person in the image, obtaining the confidence values from the multiple binary classifiers, aggregating the confidence values, and generating an age estimation for the person in the image based on the aggregated confidence values.

1. A computer-implemented method comprising:
receiving a representation of an object; submitting the representation to multiple binary classifiers that are each trained to output (i) a result of classifying the object with respect to a particular characteristic, and (ii) a confidence value for the result, wherein the confidence value reflects a degree of confidence that the binary classifier has in the binary classifier's result of classifying the object with respect to the particular characteristic; aggregating the confidence values that each reflect the degree of confidence that one of the multiple binary classifiers has in its result of classifying the object with respect to the particular characteristic; and generating an estimated value for the object, with respect to the particular characteristic, based on the aggregated confidence values that each reflect the degree of confidence that one of the multiple binary classifiers has in its result of classifying the object with respect to the particular characteristic.
