The invention provides a click rate prediction model training method, a recommendation method, a device, electronic equipment and a storage medium. The click rate prediction model training method comprises the steps of acquiring sample features and click results, corresponding to users, of the sample features; initializing a click rate prediction model according to set weight parameters; processing the sample features through the click rate prediction model to obtain a predicted click rate; constructing a target function according to an error between the click result and the predicted click rate and a zero norm regular term; and reversely propagating the error in the click rate prediction model through the target function, and updating a weight parameter of the click rate prediction modelin a propagation process. Through the click rate prediction method and device, the sparsity of the weight parameters can be improved. The file size of the generated click rate prediction model is reduced, and the click rate prediction accuracy is improved.
