创建神经层

这个应该是重点。。。

一段代码讲述如何建立。。。

import tensorflow as tf

def add_layer(inputs,in_size,out_size,activation_function = None):
    Weights = tf.Variable(tf.random_normal([in_size,out_size]))
    # 推荐偏置初始不为 0
    biases = tf.Variable(tf.zeros([1,out_size]) + 0.1)
    Wx_plus_b = tf.matmul(inputs,Weights) + biases
    if activation_function is None:
        outputs = Wx_plus_b
    else:
        outputs = activation_function(Wx_plus_b)
    return outputs

OK，打完收工。
