Websifier model. Our key contribution is the usage of Fisher kernel (FK) to find the most important examples with the improved pseudo-label estimators using several novel met-rics. Finally, we incorporate recent unsupervised pretrain-ing method [8] to speed up representation learning by the task model. Our framework is well-suited for large-scale
