本讲目标
学会神经网络计算过程，使用基于TF2原生代码搭建你的第一个神经网络训练模型
- 当今人工智能主流方向----连接主义
- 前向传播
- 损失函数
- 梯度下降
- 学习率
- 反向传播参数更新
- Tensorflow 2常用函数
人工智能三个学派
- 行为主义：基于控制论，构建感知-动作控制系统(控制论，如平衡、行走、避障等自适应控制系统)
- 符号主义：基于算数逻辑表达式，求解问题时先把问题描述为表达式，再求解表达式(可用公式描述、实现理性思维，如专家系统)
- 连接主义：仿生学，模拟神经元连接关系（神经网络）
具体步骤
- 准备数据：采集大量“特征/标签”数据
- 搭建网络：搭建神经网络结构
- 优化参数：训练网络获取最佳参数
- 应用网络：将网络保存为模型，输入新数据，输出分类或预测结果

loss = tf.square(w + 1)

神经网络在训练时，是把输入特征和标签配对后喂入网络的，Tensorflow给出了把特征和标签配对的函数
data=tf.data.Dataset.from_tensor_slices((输入特征，标签))下面我们来举个例子
features=tf.constant([12,23,10,17])
labels=tf.constant([0,1,1,0])
dataset=tf.data.Dataset.from_tensor_slices((features,labels))
print(dataset)
for element in dataset:
print(element)
(, )
(, )
(, )
(, )
常用函数tf.nn.softmax
y=tf.constant([1.01,2.01,-0.66])
y_pro=tf.nn.softmax(y)
print("After softmax,y_pro is:",y_pro)
After softmax,y_pro is: tf.Tensor([0.25598174 0.69583046 0.0481878 ], shape=(3,), dtype=float32)
常用函数assign_sub
- 赋值操作，更新参数的值并返回
- 调用
assign_sub前，先用tf.Variable定义变量w为可训练(可自更新) -
w.assign_sub（w为要自减的内容）
w=tf.Variable(4)
w.assign_sub(1)
print(w)
常用函数tf.argmax
- 返回张量沿指定维度最大值的索引
tf.argmax(张量名,axis=操作轴)
import numpy as np
test=np.array([[1,2,3],[2,3,4],[5,4,3],[8,7,2]])
print(test)
print(tf.argmax(test,axis=0))#返回每一列(经度)最大值的索引
print(tf.argmax(test,axis=1))#返回每一行(纬度)最大值的索引
[[1 2 3]
[2 3 4]
[5 4 3]
[8 7 2]]
tf.Tensor([3 3 1], shape=(3,), dtype=int64)
tf.Tensor([2 2 0 0], shape=(4,), dtype=int64)
鸢尾花分类
- 导入数据集
from sklearn import datasets
from pandas import DataFrame
import pandas as pd
x_data = datasets.load_iris().data # .data返回iris数据集所有输入特征
y_data = datasets.load_iris().target # .target返回iris数据集所有标签
print("x_data from datasets: \n", x_data)
print("y_data from datasets: \n", y_data)
x_data = DataFrame(x_data, columns=['花萼长度', '花萼宽度', '花瓣长度', '花瓣宽度']) # 为表格增加行索引（左侧）和列标签（上方）
pd.set_option('display.unicode.east_asian_width', True) # 设置列名对齐
print("x_data add index: \n", x_data)
x_data['类别'] = y_data # 新加一列，列标签为‘类别’，数据为y_data
print("x_data add a column: \n", x_data)
#类型维度不确定时，建议用print函数打印出来确认效果
