In tf.layers.conv2d, with use_bias=True, are the biases tied or untied?
tied biases is used in tf.layers.conv2d.
If you want united biases, just turn off use_bias and create bias variable manually with tf.Variable or tf.get_variable same shape with following feature map, finally sum them up.
One more question:
If they are tied biases, how can I implement untied biases?
I am using tensorflow 1.10.0 in python.
