Caffe Slice Layer

[Khan]

Hi, If I have a dense layer with 1000 nodes as a bottom blob to slice layer. I want to get 2 outputs each having 500 units. How can I do this using the slice layer?

Thanks.

Assuming there's an InnerProduct layer with num_output: 1000 and it produces a blob "dense", you should do something like this:

layer {

  type: "Slice"

  name: "slice"

  bottom: "dense"

  top: "dense1"

  top: "dense2"

  slice_param {

    axis: 1 #slice along dimension 1 - could be omitted since 1 is a default value

    slice_point: 500 #slice at index 500; indices [0-499] will go to dense1, while [500-...] to dense2

  }

}

A 32x1000 blob will be cut into 32x500 and 32x500 blobs. A 64x700x2 blob will be cut into 64x500x2 and 64x200x2. A 1x100 blob will error out.
