Interpretable machine learning model for brain metastasis in breast cancer: a large-scale, multi-center study

Quan Yuan, Yupeng Sha, Rui Yu, Hao Yu, Rongjie Ye, Yi Du, et al.

Brain metastasis (BM) is a devastating complication of breast cancer (BC) with a poor prognosis. Early identification of high-risk patients is essential but currently lacks accurate predictive tools. This study aimed to develop a stable machine learning model for predicting BM in…

Local Fokker--Planck Geometry for Score Estimation: Heat-Ball Mean-Value Representations and Exact High-Dimensional Sampling

Jiayao Bai, Lang Deng, Yi Du, Yifei Jia

Score-based generative models and Langevin samplers rely on estimating the score function $\nabla_x\log p_t(x)$ of a forward diffusion. Classically this is tractable when the drift is linear: the marginal density is Gaussian and the score is a global conditional expectation. For…
