[0075] The technical solution of the present invention will be further described below with reference to the drawings.
[0076] The MAMTL of the present invention represents the model unrelated element migration learning (Mamtl). In MamTl, it will combine with the model unrelated element learning and migration learning to realize multitasking synchronous parallel training, replacing traditional iterative training, multiple task loss functions utilize unparalleled label samples and historical conditions under different conditions. Class tag samples together update MamTL network parameters to seek global optimal solutions for network parameters, which makes MAMTL better generalization, so MamTl has more traditional migration learning in less historical conditions. Good domain adaptivity; new prototype networks are built in MamTl to represent the sample of each category of history, and the sample to be tested by calculating the similarity of the sample to the prototype by calculating...
