Tackling Heterogeneity in Medical Federated learning via Vision Transformers

no code implementations13 Oct 2023 Erfan Darzi, Yiqing Shen, Yangming Ou, Nanna M. Sijtsema, P. M. A van Ooijen

Optimization-based regularization methods have been effective in addressing the challenges posed by data heterogeneity in medical federated learning, particularly in improving the performance of underrepresented clients.

Computer-Vision Benchmark Segment-Anything Model (SAM) in Medical Images: Accuracy in 12 Datasets

no code implementations18 Apr 2023 Sheng He, Rina Bao, Jingpeng Li, Jeffrey Stout, Atle Bjornerud, P. Ellen Grant, Yangming Ou

Associations of SAM's accuracy with six factors were computed, independently and jointly, including segmentation difficulties as measured by segmentation ability score and by Dice overlap in U-Net, image dimension, size of the target region, image modality, and contrast.

U-Netmer: U-Net meets Transformer for medical image segmentation

no code implementations3 Apr 2023 Sheng He, Rina Bao, P. Ellen Grant, Yangming Ou

The global-context information among local patches is learnt by the self-attention mechanism in Transformer and U-Net segments each local patch instead of flattening into tokens to solve the `token-flatten" problem.

Segmentation Ability Map: Interpret deep features for medical image segmentation

1 code implementation19 Dec 2022 Sheng He, Yanfang Feng, P. Ellen Grant, Yangming Ou

In addition, our method can provide a mean SA score which can give a performance estimation of the output on the test images without ground-truth.

Deep Relation Learning for Regression and Its Application to Brain Age Estimation

no code implementations13 Apr 2022 Sheng He, Yanfang Feng, P. Ellen Grant, Yangming Ou

In this paper, we propose deep relation learning for regression, aiming to learn different relations between a pair of input images.

Global-Local Transformer for Brain Age Estimation

1 code implementation3 Sep 2021 Sheng He, P. Ellen Grant, Yangming Ou

The fine-grained information from the local patches are fused with the global-context information by the attention mechanism, inspired by the transformer, to estimate the brain age.
