WebScatter. Reduces all values from the src tensor into out at the indices specified in the index tensor along a given axis dim . For each value in src, its output index is specified by its index in src for dimensions outside of dim and by the corresponding value in index for dimension dim . The applied reduction is defined via the reduce argument. WebUsing the first method, you just flatten all vectors into a single vector using PyTorch’s view() method. 25 The second method uses some mathematical operation to summarize the information in the vectors. The most common operation is the arithmetic mean, but summing and using the max value along the feature map dimensions are also common.
