Abstract
A multi-language classifier (MLC) provides a single model that is able to classify inputs provided in different languages. The MLC is trained using training data comprising language data in several languages. A language-aware active learning system determines subsequent training data based on uncertainty and accuracy of classification output resulting from previous iterations. Samples associated with languages that are more uncertain and have lower accuracy are prioritized for use during subsequent training iterations. This prioritization allows training to be completed with fewer samples, particularly samples that are expensive to obtain such as those labeled by human operators. As a result, the MLC is more quickly and less expensively trained to reach desired accuracy targets.
