Embodiment Construction
[0036] It can be seen from the background technology that most of the previous research regards multi-label as an independent single-label problem and ignores the correlation between labels. This ultimately leads to an imbalance in the model's prediction performance, that is, it performs well on easier-to-predict disease labels, but performs poorly on harder-to-predict disease labels, such as pneumonia.
[0037]The present invention conducts further research on the above problems. The self-modifying label generation network (SLGN) provided in the present invention can simultaneously capture and utilize the spatial association, semantic association and co-occurrence between labels, thereby maximizing the improvement of the model. prediction accuracy. The present invention employs an encoder-decoder structure. In image captioning tasks, CNNs are used as encoders to extract image features. Image features are an abstract representation of images, including high-level semantic in...
