Abstract: A layer freezing and data sieving technique used in a sparse training domain for object recognition, providing end-to-end dataset-efficient training. The layer freezing and data sieving methods are seamlessly incorporated into a sparse training algorithm to form a generic framework. The generic framework consistently outperforms prior approaches and significantly reduces training floating point operations per second (FLOPs) and memory costs while preserving high accuracy. The reduction in training FLOPs comes from three sources: weight sparsity, frozen layers, and a shrunken dataset. The training acceleration depends on different factors, e.g., the support of the sparse computation, layer type and size, and system overhead. The FLOPs reduction from the frozen layers and shrunken dataset leads to higher actual training acceleration than weight sparsity.

Abstract: Disclosed are a positive electrode plate and a battery. A relationship is established between a thickness of an electrode plate, distribution of lithium cobalt oxide with a structure of different contents of element aluminum, and full battery cycling performance. That is, based on a thickness of the electrode plate, lithium cobalt oxide with an appropriate content of the element aluminum is selected, and distribution in a thickness direction of the positive electrode plate is changed, so that the content of Al in the thickness direction of the electrode plate generally presents a distribution trend of less content of Al in a bottom layer and more content of Al in a top layer. In this way, a problem of deterioration of high temperature cycling of a lithium-ion battery due to decreased structural stability of existing lithium cobalt oxide may be solved.
