定义Toeplitz矩阵的维度和元素: 我们需要定义Toeplitz矩阵的第一行和第一列的元素。假设我们要构造一个n x m的Toeplitz矩阵,其中n是行数,m是列数。 使用PyTorch函数构造Toeplitz矩阵: 我们可以使用循环来构造Toeplitz矩阵。以下是一个示例代码: python def create_toeplitz_matrix(first_row, first_col): n = ...
其实这里卷积核B的参数仍然只有9个,加上多个稀疏值0,来构成一个Toeplitz matrix和输入进行矩阵乘积操作。这里为什么B的shape会是16×4呢,因为其实输入是[4,4],其实是有16个值,所以第一维是16,然后因为kernel_size为3,4×4大小的输入需要计算四次,所以第二维是4。 如果你不理解Toeplitz matrix是怎么来的,你可...
