First, in face_binary_cls.cpp
, such as float conv0_weight[16*3*3*3]
,it means out_channels = 16, in_channels = 3, and size = 3.From teacher words, the weight data is RGB form.I want to know the data in the following 1-d vector, what is the form of data stored? Do it store data one out_channels after another,?And for every out_channel, it store data R,G,B alternately or store all R data first and following G data and B data in the end?
for example, one out_channel the data form is [r1,g1,b1,r2,g2,b2......,rn , gn ,bn] or [r1,r2.....,rn ,g1,g2.....,gn ,b1,b2.....,bn]?
Second, in modle.py, for this part
self.backbone = nn.Sequential(
ConvBNReLU(3, 16, 3, 2, 1), # downsampled by 2, 128 -> 64
nn.MaxPool2d(2, 2), # downsampled by 2, 64 -> 32
ConvBNReLU(16, 32, 3, 1), # keep
nn.MaxPool2d(2, 2), # downsampled by 2, 32 -> 16
ConvBNReLU(32, 32, 3, 2, 1) # downsampled by 2, 16 -> 8
)
for the forth line , it stride = 1 and padding is default value but in this situation, the out picture size will be two less than in size(30) with 3x3 conv_size .If we want to make the picture size is still 32, perhaps need 1 padding? And from 128 to 64 with 1 padding and 2 stride, for calculate formula, out size is (W-F+2P)/S+1
with W picture size = W, conv_size = F ,padding = P, stride = S, it will be 64.5 with in picture we assume have a circle of 0s but we only use left and top ,the right and bottom will not be used as long as it becomes 64?
初步看了下,simpleCNN仍然使用的是pytorch深度学习库复现,我在去年也类似复现了一个简单的手写数字识别,不调用任何第三方框架,从数学原理上实现,逐个公式各个击破,有兴趣详看参考这里 https://github.com/cuixing158/DeeplearningPractice
