In my case, because the Scale layer is being done in-place, the output and input have the same name, and that is the name of the convolution layer conv_1, not the scale layer. …
Convolves the input image with a bank of learned filters, and (optionally) adds biases. Caffe convolves by reduction to matrix multiplication. This achieves high-throughput and generality of input and filter dimensions but comes at the cost of memory for matrices. This makes use of efficiency in BLAS.
However, when I have a Caffe "Deconvolution" layer that includes a "group" parameter with value greater than 1, such as: layer { bottom: 'input' top: 'output' name: 'mylayer' …
Please use this by replacing {{}} with your values. By specifying num_output: {{C}} group: {{C}}, it behaves as channel-wise convolution.The filter shape of this deconvolution layer will be (C, 1, K, K) where K is kernel_size, and this filler will set a (K, K) interpolation kernel for every channel of the filter identically.The resulting shape of the top feature map will be (B, C, factor * …

That means you got a grouped convolution there ( Caffe: What does the group param mean? ). Technically that means that you have two filters, each of shape (128, 48, 5, 5). The first one will convolve with the first 48 channels and produce the first 128 outputs, the second one is for the remaining ones.

One channel is output by all input channels for convolution operation. If we make the convolution group equal to the input channel, the output channel is equal to the input channel, and the depthwize separable convolution structure is easily realized.

The softmax_loss layer implements both the softmax and the multinomial logistic loss (that saves time and improves numerical stability). It takes two blobs, the first one being the prediction and the second one being the label provided by the data layer (remember it?). It does not produce any outputs - all it does is to compute the loss function value, report it when backpropagation …
