Performs fractional average pooling on the input. (deprecated)
tf.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 Benjamin Graham, Fractional Max-Pooling 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). |
