# 梯度下降优化
### 通过梯度下降，并结合一些优化方法使得训练模型时参数更快更好地收敛
#### 需要安装以下扩展
` numpy
matplotlib
seaborn
ipywidgets`
### 运行 **.py即可查看效果
+ #### 原始的梯度下降算法
` python visualize_adagrad.py `
+ #### 带动量的梯度下降算法
` python visualize_sgd_momentum.py `
+ ##### 带惯性的梯度下降算法
` python visualize_sgd_inertia.py `
+ #### Nesterov算法
` python visualize_sgd_inertia.py `
+ #### Adagrad自适应调整的梯度下降
` python visualize_adagrad.py `
+ #### RMSProp
` python visualize_adagrad.py `
+ #### Adam
` python visualize_adam.py `
