使用python实现人工智能算法

使用python实现了各种机器学习的算法，也有通过tensorflow实现CNN

import numpy as np
import matplotlib.pyplot as plt
from sklearn.metrics import confusion_matrix
from sklearn.metrics import classification_report

# Define sample labels
true_labels = [2 0 0 2 4 4 1 0 3 3 3]
pred_labels = [2 1 0 2 4 3 1 0 1 3 3]

# Create confusion matrix
confusion_mat = confusion_matrix（true_labels pred_labels）

# Visualize confusion matrix
plt.imshow（confusion_mat interpolation=‘nearest‘ cmap=plt.cm.gray）
plt.title（‘Confusion matrix‘）
plt.colorbar（）
ticks = np.arange（5）
plt.xticks（ticks ticks）
plt.yticks（ticks ticks）
plt.ylabel（‘True labels‘）
plt.xlabel（‘Predicted labels‘）
plt.show（）

# Classification report
targets = [‘Class-0‘ ‘Class-1‘ ‘Class-2‘ ‘Class-3‘ ‘Class-4‘]
print（‘\n‘ classification_report（true_labels pred_labels target_names=targets））
