tensorflow 中 fully_connected

from tensorflow.contrib.layers import fully_connected 

fully_connected 全连接的参数：
def fully_connected(inputs,
num_outputs,
activation_fn=nn.relu,
normalizer_fn=None,
normalizer_params=None,
weights_initializer=initializers.xavier_initializer(),
weights_regularizer=None,
biases_initializer=init_ops.zeros_initializer(),
biases_regularizer=None,
reuse=None,
variables_collections=None,
outputs_collections=None,
trainable=True,
scope=None)

激活函数可以通过activation_fn设置，默认为relu，设置为None的时候，为线性激活
