Medical Image Analysis(2022)
摘要
•Severe data imbalance for tumor and non-tumor tissues, and among tumor sub-regions.•Loss function is dynamically updated for each class based on its performance.•Focus on harder classes with smaller sizes, complex structures, rough boundaries.•Recognize the structural relationships of tumor sub-regions.•Balance the learning capacity for global features and spatial details.
