However, currently used methods are ill-equipped to deal with biased data. The main motivation of this paper is to consider a realistic setting for pool-based semi …
Revisiting Deep Fisher Vectors: Using Fisher Information to …
WebAug 23, 2024 · This book shows machine learning enthusiasts and practitioners how to get the best of both worlds by deriving Fisher kernels from deep learning models. In addition, the book shares insight on how to store and retrieve large-dimensional Fisher vectors using feature selection and compression techniques. Feature selection and feature … 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.
