The purpose of this note is to give the change of variables formula for the local times of semimartingales, that is, a formula expressing the local times of f(X) in terms of {L_t~α(X),α∈R}.严加安科学通报(英文版)
The matrix volume is a generalization, to rectangular matrices, of the absolute value of the determinant. In particular, the matrix volume can be used in change-of-variables formulae, instead of the determinant (if the Jacobi matrix of the underlying transformation is rectangular). This result ...
瞬时换元公式[1](Instantaneous Change of Variable,ICV) 是连续时间normalizing flow (CNF)中一个核心定理。最早由NeurIPS-2018 的best paper 之一的工作 Neural ODE提出。该定理给出了在一个常微分方程定义的变换下,概率密度的变换公式。该定理可以描述为: Theorem(Instantaneous Change of Variables)(Theorem 1 [1...
回放地址 林伟-Instrumental Variables for Multiple Causal Inference: Old and New 报告内容 概述 林伟研究员(北京大学研究员,智源学者)在本次talk中主要介绍了使用instrumental variables 来进行因果推理,通过设置一系列的assumption,将IV中的经典方法Two-stage least squares扩展到高维,并得到了很好的实验结果。 主要...
Carbon offsets are widely promoted as a strategy to lower the cost of emission reductions, but recent findings suggest that offsets may not causally reduce emissions by the amount claimed. In a compliance market, offsets increase net emissions if they do
The latest CMIP6 phase aims to improve the mechanism of emission scenarios and increase the horizontal resolution, making future possibilities more plausible17,18. Nevertheless, the performance of GCMs for simulating regional climatic variables still does not satisfy the accuracy requirement of ...

Seafood is an important source of bioavailable micronutrients supporting human health, yet it is unclear how micronutrient production has changed in the past or how climate change will influence its availability. Here combining reconstructed fisheries da
Climate change is a critical factor affecting biodiversity. However, the quantitative relationship between temperature change and extinction is unclear. Here, we analyze magnitudes and rates of temperature change and extinction rates of marine fossils th
