caffe'doc 说:
layer {
name: "upsample", type: "Deconvolution"
bottom: "{{bottom_name}}" top: "{{top_name}}"
convolution_param {
kernel_size: {{2 * factor - factor % 2}} stride: {{factor}}
num_output: {{C}} group: {{C}}
pad: {{ceil((factor - 1) / 2.)}}
weight_filler: { type: "bilinear" } bias_term: false
}
param { lr_mult: 0 decay_mult: 0 }
}
我不知道为什么要这样设置 kenrel_size、stride 和 pad?
