What is the difference between 'SAME' and 'VALID' padding in tf.nn.max_pool of tensorflow?
<p>What is the difference between 'SAME' and 'VALID' padding in <code>tf.nn.max_pool</code> of <code>tensorflow</code>?</p>

<p>In my opinion, 'VALID' means there will be no zero padding outside the edges when we do max pool. </p>

<p>According to <a href="https://arxiv.org/pdf/1603.07285v1.pdf">A guide to convolution arithmetic for deep learning</a>, it says that there will be no padding in pool operator, i.e. just use 'VALID' of <code>tensorflow</code>.
But what is 'SAME' padding of max pool in <code>tensorflow</code>?</p>
