The invention discloses an improved GADT model auxiliary junk mail detection method based on a
genetic algorithm, and relates to the technical field of junk mail detection and classification, and the method comprises the following steps: S10, carrying out structured preprocessing on an input text, including text
standardization, stop word deletion and stem extraction; according to the method, feature space redundancy and
noise are effectively reduced, key
semantic information is reserved, and the data scale is compressed by performing structured preprocessing on the mail text and combining TF-IDF
feature coding and PCA dimension reduction; a
decision tree pruning parameter
confidence factor is adaptively optimized by using a
genetic algorithm, the complexity and generalization ability of the
decision tree are dynamically balanced, and the classification accuracy and the model robustness are remarkably improved; the
feature dimension reduction and model optimization cooperate to reduce the training reasoning complexity and improve the detection real-time performance, and the method is significantly superior to the prior art in accuracy, robustness and calculation efficiency, and has good expansibility and application and popularization value.
