Abstract

The embodiment of the invention provides a user caching method and device, and the method comprises the steps: finding out main features affecting the time consumption of a user interface through principal component analysis; a user interface is used for accessing data, a regression model is trained in real time, consumed time for requesting the interface by a user is predicted, a user cache index is calculated by combining user activeness features and using a variable coefficient method, and a long-tail user group is automatically delineated according to the cache index. The cache hit rate of the user interface is improved, the interface slow speed ratio is reduced, and the cache revenue maximization effect is achieved.

Description

technical field [0001] The invention relates to the field of data mining, in particular to a method and device for caching users. Background technique [0002] A common method to improve user interface performance and reduce user request interface time is to cache user data in advance. With Weibo videos with hundreds of millions of users, the cost of caching all user data in advance is too high. Cache user mining is a method of data mining to mine out the part of users who need the most cache from a large number of users, so as to maximize the cache benefit. [0003] Common cache user mining methods in the industry mainly include rule method and random extraction method. These methods are easy to implement and highly operable, but have the following disadvantages: [0004] Disadvantage 1: The cache hit rate is low, resulting in a waste of cache resources. Users are delineated based on rules or random selection, and there is a high probability that inactive users will be c...
