The present application relates to the technical field of
deep learning, in particular to a novel
deep learning method and device based on symmetric cross compound training, which specifically comprises: obtaining first sample data, dividing the first sample data into a first
training set, a first validation set and a first
test set, and further dividing the first
training set into a first
data set and a second
data set; taking the first
data set and the second data set alternately as a
training set and a validation set to perform symmetric
cross training, obtaining
outlier samples and true samples; performing compound training on the
outlier samples and the true samples, simultaneously performing output correction classification, and obtaining a first optimal model. The present application changes the traditional
deep learning training method mode, uses the function of deep learning
feature extraction to automatically identify and separate the
outlier samples in the training set, and further improves the model performance.
