tf.compat.v1.nn.fractional_avg_pool

Performs fractional average pooling on the input. (deprecated)

tf.compat.v1.nn.fractional_avg_pool(
    value, pooling_ratio, pseudo_random=False, overlapping=False,
    deterministic=False, seed=0, seed2=0, name=None
)

This is a deprecated version of fractional_avg_pool.

Fractional average pooling is similar to Fractional max pooling in the pooling region generation step. The only difference is that after pooling regions are generated, a mean operation is performed instead of a max operation in each pooling region.

Args
value	A Tensor. 4-D with shape [batch, height, width, channels].
pooling_ratio	A list of floats that has length >= 4. Pooling ratio for each dimension of value, currently only supports row and col dimension and should be >= 1.0. For example, a valid pooling ratio looks like [1.0, 1.44, 1.73, 1.0]. The first and last elements must be 1.0 because we don't allow pooling on batch and channels dimensions. 1.44 and 1.73 are pooling ratio on height and width dimensions respectively.
pseudo_random	An optional bool. Defaults to False. When set to True, generates the pooling sequence in a pseudorandom fashion, otherwise, in a random fashion. Check paper (Graham, 2015) for difference between pseudorandom and random.
overlapping	An optional bool. Defaults to False. When set to True, it means when pooling, the values at the boundary of adjacent pooling cells are used by both cells. For example: index 0 1 2 3 4 value 20 5 16 3 7 If the pooling sequence is [0, 2, 4], then 16, at index 2 will be used twice. The result would be [20, 16] for fractional avg pooling.
deterministic	An optional bool. Deprecated; use fractional_avg_pool_v2 instead.
seed	An optional int. Defaults to 0. If set to be non-zero, the random number generator is seeded by the given seed. Otherwise it is seeded by a random seed.
seed2	An optional int. Deprecated; use fractional_avg_pool_v2 instead.
name	A name for the operation (optional).

Returns

A tuple of Tensor objects (output, row_pooling_sequence, col_pooling_sequence). output: Output Tensor after fractional avg pooling. Has the same type as value. row_pooling_sequence: A Tensor of type int64. col_pooling_sequence: A Tensor of type int64.
