支持向量机libsvm的使用指南

最近一项目需要对采样的数据进行拟合建模,正常情况下,需要预先建立函数模型,然后再根据样本利用类似最小二乘的办法解算函数模型系数,然而考虑到被采样数据函数模型难以建立,所以需要一种通用函数逼近器。本欲使用小波神经网络来做此事,后来通过IRC好友d0048交流得知,支持向量机(Support Vector Machines,SVM)是一种更经典的通用函数逼近器,而更是得知,台湾大学林智仁(Chih-J...阅读全文

卡尔曼滤波原理及实例

卡尔曼滤波器又被称作“最佳线性滤波器”,它实现简单,在工程应用面上极广。而GNSS上面,卡尔曼滤波也有着两个主要应用: RTK算法与动态周跳探测。卡尔曼滤波来自于Rudof Emil Kalman在1960年发表的论文《A New Approach to Linear Filtering and Prediction Problmes》,此处是下载地址. 本文将以一个简单的例子来帮助理解卡尔曼波器...阅读全文
