Python Kalman filtering and optimal estimation library. Implements Kalman filter, particle filter, Extended Kalman filter, Unscented Kalman filter, g-h (alpha-beta), least squares, H Infinity, smoothers, and more. Has companion book 'Kalman and Bayesian
However, as I began to finally understand the Kalman filter I realized the underlying concepts are quite straightforward. A few simple probability rules, some intuition about how we integrate disparate knowledge to explain events in our everyday life and the core concepts of the Kalman filter are...
题记:毕业一年多天天coding,好久没写paper了。在这动荡的日子里,也希望写点东西让自己静一静。恰好前段时间用python做了一点时间序列方面的东西,有一丁点心得体会想和大家分享下。在此也要特别感谢顾志耐和散沙,让我喜欢上了python。 什么是时间序列 时间序列简单的说就是各时间点上形成的数值序列,时间序列分析就是...
