Fine-Grained Thyroid Nodule Classification via Multi-Semantic Attention Network

Thyroid nodule classification in ultrasound images has gained great momentum based on deep convolutional neural networks in recent years. Nevertheless, it is still challenging to intelligently classify the fine-grained thyroid nodules, which is significant for the subsequent clinical treatments. The difficulties mainly stem from four aspects: few fine-grained training dataset, highly-variable appearances of intra-class nodules, overall-similar...
