Expired gas identification method and device, computer equipment and storage medium

The invention relates to the technical field of medical treatment in artificial intelligence, and discloses an expired gas identification method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring teacher coding parameter information of a target teacher model; acquiring an expiration data set, and inputting the expiration data set and the teacher coding parameter information into an encoder module of a student model to obtain a student coding result; inputting the student coding result into a decoder module of a student model to obtain a first loss; inputting the expiration data set into a target teacher model for encoding to obtain a teacher encoding result, and calculating according to the teacher encoding result and the student encoding result to obtain a second loss; performing iterative training on the student model according to the first loss and the second loss to obtain a target student model; and acquiring to-be-identified expired gas data, and inp
