Active learning strategies using SVMs

Ming-Hen Tsai, Chia-Hua Ho, Chih-Jen Lin

Abstract: In this paper, we decompose the problem of active learning into two parts, learning with few examples and learning by querying labels of samples. The first part is achieved mainly by SVM classifiers. We also consider variants based on transductive learning. In the second part, based on SVM decision values, we propose a framework to flexibly select points for query. Our experiments are conducted on the data sets of Causality Active Learning Challenge. With measurements of Area Under Curve (AUC) and Area under the Learning Curve (ALC), we find suitable methods for different data sets.
