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
 }
 }
