Caffe 学习:Eltwise层
Eltwise层的操作有三个:product(点乘), sum(相加减) 和 max(取大值),其中sum是默认操作。
假设输入(bottom)为A和B,如果要实现element_wise的A+B,即A和B的对应元素相加,prototxt文件如下:
layer { name: "eltwise_layer" type: "Eltwise" bottom: "A" bottom: "B" top: "diff" eltwise_param { operation: SUM } }
如果实现A-B,则prototxt为:
layer { name: "eltwise_layer" type: "Eltwise" bottom: "A" bottom: "B" top: "diff" eltwise_param { operation: SUM coeff: 1 coeff: -1 } }
其中A和B的系数(coefficient)都要给出!
