Iris数据集的Fisher线性分类及可视化

一、线性分类及准确率 import pandas as pd import numpy as np import matplotlib.pyplot as plt path=r'F:/人工智能与机器学习/iris.csv' df = pd.read_csv(path, header=0) Iris1=df.values[0:50,0:4] Iris2=df.values[50:100,0:4] Iris3=df.values[100:150,0:4] m1=np.mean(Iris1,axis=0) m2=np.mean(Iris2,axis=0) m3=np.mean(Iris3,axis=
