Focus classification method based on multi-modal data and related products

The invention relates to the technical field of neural networks in artificial intelligence, and discloses a focus classification method based on multi-modal data and related products. The focus classification method based on the multi-modal data comprises the steps: obtaining a first medical image and a second medical image, wherein the first medical image and the second medical image are medicalimages obtained by the same part in different imaging modes, and the space complexity of the first medical image is larger than that of the second medical image; performing feature extraction on the first medical image through a first network to obtain a first feature map; performing feature extraction on the first medical image through a second network to obtain a second feature map; performing feature extraction on the second medical image through a third network to obtain a third feature map; and performing classification according to the first feature map, the second feature map and the third feature map to obtain
