ResNet:

一、介绍

这里写图片描述

name: "ResNet_50_1by2"layer {  name: "data"  type: "Input"  top: "data"  input_param { shape: { dim: 1 dim: 3 dim: 224 dim: 224 } }   // 第一个维度是图片数,第二个是通道数,后面的是图片的长宽}layer {  name: "conv_1"  type: "Convolution"  bottom: "data"  top: "conv_1"  param {    lr_mult: 1    decay_mult: 1  }  param {    lr_mult: 2    decay_mult: 0  }  convolution_param {    num_output: 64    pad: 3    kernel_size: 7    stride: 2    weight_filler {      type: "xavier"    }    bias_filler {      type: "constant"      value: 0    }  }}

shape {

dim: 1 #num,可自行定义
dim: 3 #通道数,表示RGB三个通道
dim: 32 #图像的长和宽,通过 _train_test.prototxt文件中数据输入层的crop_size获取
dim: 32}

二、训练

深度残差网(deep residual networks)的训练过程

1、下载基于python的训练代码:

2、pyfunt需要安装:
