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.

Abstract: A method of assigning numbers to flights includes displaying, in a first window that is displayed on a GUI, a slideable scale that receives a pairing preference input that indicates a user preference relating to the classification of flights as thru flights relative to the classification of flights as out-and-back flights. The method also includes: after displaying the first window, receiving by a processor the pairing preference input; in response to the receipt of the pairing preference input, classifying, using a flight number optimization model, each flight as one of: a thru flight, an out-and-back flight, and a stand-alone flight based on the pairing preference input; assigning, using the flight number optimization model, a number to each flight; and displaying, in a second window that is displayed on the GUI, at least a portion of an output schedule that comprises assigned numbers for each flight.
