Power Layer

• Layer type: Power
• Doxygen Documentation
• Header: ./include/caffe/layers/power_layer.hpp
• CPU implementation: ./src/caffe/layers/power_layer.cpp
• CUDA GPU implementation: ./src/caffe/layers/power_layer.cu

The Power layer computes the output as (shift + scale * x) ^ power for each input element x.

Parameters

• Parameters (PowerParameter power_param)
  • Optional
    • power [default 1]
    • scale [default 1]
    • shift [default 0]
• From ./src/caffe/proto/caffe.proto:

message PowerParameter {
  // PowerLayer computes outputs y = (shift + scale * x) ^ power.
  optional float power = 1 [default = 1.0];
  optional float scale = 2 [default = 1.0];
  optional float shift = 3 [default = 0.0];
}

Sample

  layer {
    name: "layer"
    bottom: "in"
    top: "out"
    type: "Power"
    power_param {
      power: 1
      scale: 1
      shift: 0
    }
  }
