caffe message学习之FillerParameter

github源码传送门，

其源码如下所示，

message FillerParameter {  // The filler type.  optional string type = 1 [default = 'constant'];  optional float value = 2 [default = 0]; // the value in constant filler  optional float min = 3 [default = 0]; // the min value in uniform filler  optional float max = 4 [default = 1]; // the max value in uniform filler  optional float mean = 5 [default = 0]; // the mean value in Gaussian filler  optional float std = 6 [default = 1]; // the std value in Gaussian filler  // The expected number of non-zero output weights for a given input in  // Gaussian filler -- the default -1 means don't perform sparsification.  optional int32 sparse = 7 [default = -1];  // Normalize the filler variance by fan_in, fan_out, or their average.  // Applies to 'xavier' and 'msra' fillers.  enum VarianceNorm {    FAN_IN = 0;    FAN_OUT = 1;    AVERAGE = 2;  }  optional VarianceNorm variance_norm = 8 [default = FAN_IN];}
