WebIt is basically to average (or reduce) the input data (say C ∗ H ∗ W) across its channels (i.e., C ). Convolution with one 1 x 1 filter generates one average result in shape H ∗ W. The 1 x 1 filter is actually a vector of length C. When you have F 1 x 1 filters, you get F averages. That means, your output data shape is F ∗ H ∗ W. WebMay 12, 2024 · The mean and standard deviation required to standardize pixel values can be calculated from the pixel values in each image only (sample-wise) or across the entire training dataset (feature-wise).
