Problems solved by technology

[0002] The inventor found that in the existing distributed image storage system, the amount of data is large and the data is discrete, and the traditional data prediction method directly caches the adjacent data in time or space for prediction, so there is a problem of low hit rate of data prediction

Embodiment Construction

[0044] The distributed image storage system has two characteristics: one is the large amount of data, the cluster scale can be expanded to thousands of storage nodes, and can store hundreds of billions of image data; the other is the discrete data, mainly manifested in discrete data sources and discrete storage spaces The storage time is discrete, and the picture data from thousands of front-end cameras is continuously stored in different disks of different storage nodes 24 / 7.

[0045] In today's big data era, there is often an "internal" correlation between data and data, and the associated data is often accessed in a short period of time, such as face recognition in AI application scenarios, image search Figures, etc., require matching image data with similar characteristics within seconds. In this scenario, due to the complete randomness of the image data distribution, the traditional associated data prediction algorithms related to temporal locality and spatial locality wi...

Abstract

The embodiment of the invention provides a data prediction method and device, electronic equipment and a storage medium, and relates to the technical field of data prediction. The data prediction method comprises the steps that firstly, historical track data of to-be-processed picture data is acquired, and the historical track data represents the access sequence of the to-be-processed picture data; secondly, calculating according to the historical track data to obtain an associated value of the to-be-processed picture data; and then, predicting associated picture data of the to-be-processed picture data according to the association value. Through the method, data prediction can be carried out according to the data in the access sequence, and the problem that the hit rate of data prediction is low due to the fact that time or space adjacent data is directly cached for prediction in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of data prediction, and in particular, to a data prediction method and device, electronic equipment, and a storage medium. Background technique [0002] The inventor found that in the existing distributed image storage system, the amount of data is large and the data is discrete, and the traditional data prediction method directly caches the adjacent data in time or space for prediction, so there is a problem of low hit rate of data prediction . Contents of the invention [0003] In view of this, the purpose of this application is to provide a data prediction method and device, electronic equipment and storage medium, so as to improve the problems existing in the prior art. [0004] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions: [0005] In a first aspect, the present invention provides a data prediction method, compris...
