原创 CNN识别手写数字-莫烦python
搭建一个 CNN识别手写数字 前面跟着莫烦python/tensorflow教程完成了神经网络识别手写数字的代码。 import tensorflow as tf from tensorflow.examples.tutorials.mnist import input_data mnist = input_data.read_data_sets('MNIST_data', one_hot = True) def compute_accuracy(v_xs, v_ys): # 计算精度函数

原创 用Tensorflow框架搭建神经网络
用Tensorflow框架搭建神经网络 import tensorflow as tf import numpy as np import matplotlib.pyplot as plt def addlayer(inputs, insize, outsize, activation_function=None): Weights = tf.Variable(tf.random_normal([insize, outsize])) # 定义权值矩阵，一般初始值为随机数比赋全0要好 bi

原创 TensorFlow 莫烦python
这里写自定义目录标题 举个栗子 #create data x_data = np.random.rand(100).astype(np.float32) y_data = x_data *0.1 +0.3 #create tensorflow structure start# Weight = tf.Variable(tf.random_uniform([1], -1.0,1.0)) biases = tf.Variable(tf.zeros([1])) y = Weight * x_data +
