新的变分方法使用Wasserstein-Fisher-Rao几何进行霍克斯过程强度估计

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-15 04:00

研究人员开发了一种新的变分方法，用于估计霍克斯过程的背景强度，特别是在已知触发机制但背景密度未知的情况下。该方法利用Wasserstein-Fisher-Rao几何和分布框架来处理不属于经典梯度流公式的动力学。该方法涉及将这些动力学投影到统计流形上，以推导出有限维方案，并侧重于高斯混合流形以实现实际应用。 AI

影响引入了一种新的点过程强度估计统计方法，可能适用于异常检测或事件预测等领域。

Hawkes背景强度估计的预测Wasserstein-Fisher-Rao流

arXiv:2610.19588v1 Announce Type: cross Abstract: We consider the problem of estimating the background intensity of a Hawkes process when the triggering mechanism is known, treating the background as an unknown finite positive measure with a regular density. We propose a likeliho…
