tensorflow::ops::MaxPoolWithArgmax

#include <nn_ops.h>

Performs max pooling on the input and outputs both max values and indices.

Summary

The indices in argmax are flattened, so that a maximum value at position [b, y, x, c] becomes flattened index: (y * width + x) * channels + c if include_batch_in_index is False; ((b * height + y) * width + x) * channels + c if include_batch_in_index is True.

The indices returned are always in [0, height) x [0, width) before flattening, even if padding is involved and the mathematically correct answer is outside (either negative or too large). This is a bug, but fixing it is difficult to do in a safe backwards compatible way, especially due to flattening.

Args:

  • scope: A Scope object
  • input: 4-D with shape [batch, height, width, channels]. Input to pool over.
  • ksize: The size of the window for each dimension of the input tensor.
  • strides: The stride of the sliding window for each dimension of the input tensor.
  • padding: The type of padding algorithm to use.

Optional attributes (see Attrs):

  • include_batch_in_index: Whether to include batch dimension in flattened index of argmax.

Returns:

  • Output output: The max pooled output tensor.
  • Output argmax: 4-D. The flattened indices of the max values chosen for each output.
