Chunk, Align, Select: A Simple Long-sequence Processing Method for Transformers

no code implementations25 Aug 2023 Jiawen Xie, Pengyu Cheng, Xiao Liang, Yong Dai, Nan Du

Although dominant in natural language processing, transformer-based models remain challenged by the task of long-sequence processing, because the computational cost of self-attention operations in transformers swells quadratically with the input sequence length.

Automatic lobe segmentation using attentive cross entropy and end-to-end fissure generation

no code implementations24 Jul 2023 Qi Su, Na Wang, Jiawen Xie, Yinan Chen, Xiaofan Zhang

Therefore, we propose a new automatic lung lobe segmentation framework, in which we urge the model to pay attention to the area around the pulmonary fissure during the training process, which is realized by a task-specific loss function.
