Recommendation method and device, electronic equipment and storage medium

The invention discloses a recommendation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a scoring matrix, and determining a training set and a verification set according to the scoring matrix; according to the scoring matrix, a first matrix is initialized in combination with the rank of a preset hidden space; obtaining a predicted value corresponding to each element in the training set based on the first matrix; updating the first matrix through stochastic gradient descent according to the error between the predicted value and the score value; determining evaluation indexes through the verification set based on the updated first matrix, and then returning to the step of obtaining the predicted value corresponding to each element in the training set based on the first matrix until the difference between two adjacent evaluation indexes is smaller than a preset threshold value or reaches a preset training round; and according to the first matrix obtain
