Abstract
Supervised learning requires adequately labeled training data. In this paper, we present an approach for automatic detection of outliers in image training sets using an one-class support vector machine (SVM). The image sets were downloaded from photo communities solely based on their tags. We conducted four experiments to investigate if the one-class SVM can automatically differentiate between target and outlier images. As testing setup, we chose four image categories, namely Snow & Skiing, Family & Friends, Architecture & Buildings and Beach. Our experiments show that for all tests a significant tendency to remove the outliers and retain the target images is present. This offers a great possibility to gather big data sets from the Web without the need for a manual review of the images.
