tf.pad(one_hot_encoding, [[0, 0], [1, 0]], mode=‘CONSTANT‘)
tf.pad 是扩展的意思,其中[0, 0], [1, 0] 分别代表的是[上,下][左,右] 值为0代表相应边扩展0,比如上面代码中,左的位置的值为0,代表在左边增加一列,填充是mode=‘CONSTANT‘,代表用0填充,具体见:
https://www.tensorflow.org/api_docs/python/tf/pad
# ‘t‘ is [[1, 2, 3], [4, 5, 6]].
# ‘paddings‘ is [[1, 1,], [2, 2]].
# ‘constant_values‘ is 0.
# rank of ‘t‘ is 2.
pad(t, paddings, "CONSTANT") ==> [[0, 0, 0, 0, 0, 0, 0],
[0, 0, 1, 2, 3, 0, 0],
[0, 0, 4, 5, 6, 0, 0],
[0, 0, 0, 0, 0, 0, 0]]
pad(t, paddings, "REFLECT") ==> [[6, 5, 4, 5, 6, 5, 4],
[3, 2, 1, 2, 3, 2, 1],
[6, 5, 4, 5, 6, 5, 4],
[3, 2, 1, 2, 3, 2, 1]]pad(t, paddings, "SYMMETRIC") ==> [[2, 1, 1, 2, 3, 3, 2],
[2, 1, 1, 2, 3, 3, 2],
[5, 4, 4, 5, 6, 6, 5],
[5, 4, 4, 5, 6, 6, 5]]
tf.pad(one_hot_encoding, [[0, 0], [1, 0]], mode='CONSTANT')
