Intersection formulas on moduli spaces of unitary shtukas
Feng-Yun-Zhang have proved a function field analogue of the arithmetic
Siegel-Weil formula, relating special cycles on moduli spaces of unitary
shtukas to higher derivatives of Eisenstein series. We prove an extension of
this formula in a low-dimensional case, and deduce from it a Gross-Zagier style
formula expressing intersection multiplicities of cycles in terms of higher
derivatives of base-change -functions.Comment: 29 page

Abdominal multi-organ segmentation in CT using Swinunter
Abdominal multi-organ segmentation in computed tomography (CT) is crucial for
many clinical applications including disease detection and treatment planning.
Deep learning methods have shown unprecedented performance in this perspective.
However, it is still quite challenging to accurately segment different organs
utilizing a single network due to the vague boundaries of organs, the complex
background, and the substantially different organ size scales. In this work we
used make transformer-based model for training. It was found through previous
years' competitions that basically all of the top 5 methods used CNN-based
methods, which is likely due to the lack of data volume that prevents
transformer-based methods from taking full advantage. The thousands of samples
in this competition may enable the transformer-based model to have more
excellent results. The results on the public validation set also show that the
transformer-based model can achieve an acceptable result and inference time.Comment: 8pages. arXiv admin note: text overlap with arXiv:2201.01266 by other

Data-Centric Diet: Effective Multi-center Dataset Pruning for Medical Image Segmentation
This paper seeks to address the dense labeling problems where a significant
fraction of the dataset can be pruned without sacrificing much accuracy. We
observe that, on standard medical image segmentation benchmarks, the loss
gradient norm-based metrics of individual training examples applied in image
classification fail to identify the important samples. To address this issue,
we propose a data pruning method by taking into consideration the training
dynamics on target regions using Dynamic Average Dice (DAD) score. To the best
of our knowledge, we are among the first to address the data importance in
dense labeling tasks in the field of medical image analysis, making the
following contributions: (1) investigating the underlying causes with rigorous
empirical analysis, and (2) determining effective data pruning approach in
dense labeling problems. Our solution can be used as a strong yet simple
baseline to select important examples for medical image segmentation with
combined data sources.Comment: Accepted by ICML workshops 202
