Automatic machine learning platform and method for network security application

The embodiment of the invention provides a network security application-oriented automatic machine learning platform and method. The platform comprises a data preprocessing module, a sample and label generation module, a feature extraction module and a model training module. The data preprocessing module is used for preprocessing the traffic data to obtain a behavior sequence corresponding to the user ID; the sample and label generation module is used for generating a sample and a label corresponding to the sample according to the behavior sequence corresponding to the user ID; the feature extraction module is used for performing feature extraction on the samples to obtain sample features; and the model training module is used for constructing an initial model by adopting a model structure corresponding to the data format of the sample features, and training the initial model by utilizing the sample features and the labels corresponding to the sample features to obtain a target model. In this way, user partic
