[0121] In order to illustrate the improved effect of the present invention in terms of time and accuracy, an authoritative data set in the field of resource recommendation, the MovieLens recommendation system, is used for experiments. This data set records the ratings of movie resources by users in the system. The ratings are integers from 1 to 5. The higher the score, the higher the rating.
[0122] In addition, in order to observe the effect of the method on data sets of different scales, the original MovieLens data set is divided into five subsets of 200, 500, 1000, 2000 and 3500 according to the number of users. The corresponding number of rated resources are 2833, 3172, 3381, 3580 and 3633 respectively. In addition, the activation function of the single hidden layer neural network model is set to be an S-type function, and the number of hidden layer nodes is fixed at 30.
