|
| 6 | * Computes a 2D convolution over the input x.
|
| 7 | *
|
| 8 | * @param x The input tensor, of rank 4 or rank 3, of shape
|
| 9 | * `[batch, height, width, inChannels]`. If rank 3, batch of 1 is
|
| 10 | * assumed.
|
| 11 | * @param filter The filter, rank 4, of shape
|
| 12 | * `[filterHeight, filterWidth, inDepth, outDepth]`.
|
| 13 | * @param strides The strides of the convolution: `[strideHeight,
|
| 14 | * strideWidth]`.
|
| 15 | * @param pad The type of padding algorithm.
|
| 16 | * - `same` and stride 1: output will be of same size as input,
|
| 17 | * regardless of filter size.
|
| 18 | * - `valid`: output will be smaller than input if filter is larger
|
| 19 | * than 1x1.

|
| 23 | * @param dataFormat: An optional string from: "NHWC", "NCHW". Defaults to
|
| 24 | * "NHWC". Specify the data format of the input and output data. With the
|
| 25 | * default format "NHWC", the data is stored in the order of: [batch,
|
| 26 | * height, width, channels].
|
| 27 | * @param dilations The dilation rates: `[dilationHeight, dilationWidth]`
|
| 28 | * in which we sample input values across the height and width dimensions
|
| 29 | * in atrous convolution. Defaults to `[1, 1]`. If `dilations` is a single
|
| 30 | * number, then `dilationHeight == dilationWidth`. If it is greater than
|
| 31 | * 1, then all values of `strides` must be 1.
|
| 32 | * @param dimRoundingMode A string from: 'ceil', 'round', 'floor'. If none is
|
| 33 | * provided, it will default to truncate.
