| 22 | * Computes the 2D average pooling of an image.
|
| 23 | *
|
| 24 | * @param x The input tensor, of rank 4 or rank 3 of shape
|
| 25 | * `[batch, height, width, inChannels]`. If rank 3, batch of 1 is assumed.
|
| 26 | * @param filterSize The filter size: `[filterHeight, filterWidth]`. If
|
| 27 | * `filterSize` is a single number, then `filterHeight == filterWidth`.
|
| 28 | * @param strides The strides of the pooling: `[strideHeight, strideWidth]`. If
|
| 29 | * `strides` is a single number, then `strideHeight == strideWidth`.
|
| 30 | * @param pad The type of padding algorithm:
|
| 31 | * - `same` and stride 1: output will be of same size as input,
|
| 32 | * regardless of filter size.
|
| 33 | * - `valid`: output will be smaller than input if filter is larger
|
| 34 | * than 1x1.
