homework1_of_pattern_recognition_and_meachine_learning's Introduction

简介

作者:槐泽鹏

内容:《模式识别和机器学习-博士课程》的第一次大作业——《参数法和非参数法分类器》

参考

参考:https://github.com/pamela0530/bayes

原来代码有两处错误:

1 判别函数少了“协方差矩阵行列式”此项。

2 MQDF算法中计算修正的协方差矩阵时,直接输出了原矩阵,并且代码逻辑较为混乱,因此进行了重新改写。

内容

实现四种参数法高斯分类器LDF、QDF、RDA、MQDF和一种非参数分类器parzen windows。

运行环境: Python >3

requirenments: pandas,sklearn,matplotlib,numpy

使用

1 不需在联网环境下获取数据

2 LDF、QDF、RDA、MQDF方法调用接口为gaussianlinear.py

3 parzen windows 方法接口文件为bayes.py
