The application discloses a kind of multi-modal face anti-fraud methods for domain generalization, it is related to face recognition technical field, multiple source domains under multi-modal face image are collected, and data set is constructed;Face anti-fraud model is constructed, and multiple modal image coding module is configured for each source domain, and multiple modal fusion features are generated, and classification head is configured for each source domain, and the prediction result of corresponding domain is output according to multiple modal fusion features, domain relationship extraction module is configured, the inter-domain relationship weight between each source domain is extracted, and the prediction result of each source domain is fused according to inter-domain relationship weight, and the final prediction result is obtained;The model is trained, including intra-domain modal level optimization and domain level optimization.The application introduces the center difference expansion convolution module of adaptive receptive field, combines inter-domain relationship weighted multi-head fusion framework, solves the problem that multi-modal feature extraction is insufficient in the prior art, and the cross-domain generalization ability is weak, realizes complex scene, unknown domain under accurate face anti-fraud detection.

The utility model provides a kind of switchable dual superchargers, it is related to supercharger technical field, comprising: supercharger assembly, supercharger assembly is by supercharger mechanism, protective shell and air intake shell is constituted, protective shell and air intake shell are respectively arranged in the two sides of supercharger mechanism, supercharger assembly is commonly provided with two, by the setting of switching component, the working condition between two supercharger assemblies can be switched in the process of use, by opening drive motor and driving three-way valve piece rotation, so that three-way valve piece circular one end is parallel with connecting pipe, at this time under the action of three-way valve piece, two air intake shells are interconnected by connecting pipe, further opening drive motor and driving three-way valve piece rotation, so that three-way valve piece semicircular one end is parallel with connecting pipe, so that connecting pipe is communicated with one air intake shell, realize the switching effect between two air intake shells.
