/**
|
* 2-D convolution with separable filters.
|
*
|
* Performs a depthwise convolution that acts separately on channels followed
|
* by a pointwise convolution that mixes channels. Note that this is
|
* separability between dimensions [1, 2] and 3, not spatial separability
|
* between dimensions 1 and 2.
|
*
|
* See
|
* [https://www.tensorflow.org/api_docs/python/tf/nn/separable_conv2d](
|
* https://www.tensorflow.org/api_docs/python/tf/nn/separable_conv2d)
|
* for more details.
|
*
|
* @param x The input tensor, of rank 4 or rank 3, of shape
|
* `[batch, height, width, inChannels]`. If rank 3, batch of 1 is
|
* assumed.
|
* @param depthwiseFilter The depthwise filter tensor, rank 4, of shape
|
* `[filterHeight, filterWidth, inChannels, channelMultiplier]`. This is
|
* the filter used in the first step.
|
* @param pointwiseFilter The pointwise filter tensor, rank 4, of shape
|
* `[1, 1, inChannels * channelMultiplier, outChannels]`. This is
|
* the filter used in the second step.
|
* @param strides The strides of the convolution: `[strideHeight,
|
* strideWidth]`. If strides is a single number, then `strideHeight ==
|
* strideWidth`.
|
* @param pad The type of padding algorithm.
|
* - `same` and stride 1: output will be of same size as input,
|
* regardless of filter size.
|
* - `valid`: output will be smaller than input if filter is larger
|
* than 1x1.
|
* - For more info, see this guide:
|
* [https://www.tensorflow.org/api_docs/python/tf/nn/convolution](
|
* https://www.tensorflow.org/api_docs/python/tf/nn/convolution)
|
* @param dilations The dilation rates: `[dilationHeight, dilationWidth]`
|
* in which we sample input values across the height and width dimensions
|
* in atrous convolution. Defaults to `[1, 1]`. If `rate` is a single
|
* number, then `dilationHeight == dilationWidth`. If it is greater than
|
* 1, then all values of `strides` must be 1.
|
* @param dataFormat: An optional string from: "NHWC", "NCHW". Defaults to
|
* "NHWC". Specify the data format of the input and output data. With the
|
* default format "NHWC", the data is stored in the order of: [batch,
|
* height, width, channels]. Only "NHWC" is currently supported.
