Abstract
Disclosed are a method for updating data of a refrigerator freshness reservation model, a device and a storage medium. The method includes: S1, collecting refrigerator information of a plurality of users, wherein the refrigerator information of each user includes an item identifier corresponding to each of stored items in a refrigerator, and a usage frequency; S2, performing statistical computation on the refrigerator information to acquire a mean and a variance of usage frequencies corresponding to each food identifier; and S3, screening the refrigerator information based on the acquired mean and variance. In the present invention, uploaded data are automatically screened in an optimizing manner by mutual cooperation between the means and the variances, such that the uploaded data can be filtered, thereby maintaining the calculation accuracy while reducing the pressure on a server.
