/**
 * ## DeConv1d
 *
 * Performs the transpose of 1-D convolution operation.
 *
 * This operation is sometimes called "deconvolution1d" after Deconvolutional Networks,
 * but is actually the transpose (gradient) of Conv2D rather than an actual deconvolution.
 *
 * - weights : the channel number for weight tensor.
 * - ksize : the length for weight tensor.
 * - padding : AUTO, VALID or SAME.
 * - pad : pad value for each spatial axis.
 * - stride : stride along each spatial axis.
 * - output_padding : specifying the amount of padding along the height and width of
 * the output tensor.
