The invention provides a machine learning recognition method based on deep learning. Multiple times of different learning training can be performed on a machine learning model f1 with a certain quantity of known classes of multimedia data samples in different contrast sample input arranging orders, the machine learning model f1 obtained by learning is used for recognizing multimedia data classes and selects a convolutional neural network model or a fully connected neural network model, dependence on a huge number of training samples is reduced substantially, the multimedia data classes not subjected to learning training can be expanded conveniently for class recognition, the problem that practical applicability and generality are limited due to dependence of the conventional machine learning method for multimedia data classification on the huge number of training samples and failure in direct classification recognition on the classes not subjected to learning training is solved well, and the machine learning recognition method can be applied to more specific multimedia data classification occasions more extensively and more effectively.
