| 22 | * Computes a 1D convolution over the input x.
|
| 23 | *
|
| 24 | * @param x The input tensor, of rank 3 or rank 2, of shape
|
| 25 | * `[batch, width, inChannels]`. If rank 2, batch of 1 is assumed.
|
| 26 | * @param filter The filter, rank 3, of shape
|
| 27 | * `[filterWidth, inDepth, outDepth]`.
|
| 28 | * @param stride The number of entries by which the filter is moved right at
|
| 29 | * each step.
|
| 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.

|
| 38 | * @param dataFormat An optional string from "NWC", "NCW". Defaults to "NWC",
|
| 39 | * the data is stored in the order of [batch, in_width, in_channels]. Only
|
| 40 | * "NWC" is currently supported.
|
| 41 | * @param dilation The dilation rate in which we sample input values in
|
| 42 | * atrous convolution. Defaults to `1`. If it is greater than 1, then
|
| 43 | * stride must be `1`.
|
| 44 | * @param dimRoundingMode A string from: 'ceil', 'round', 'floor'. If none is
|
| 45 | * provided, it will default to truncate.
