假設我已經定義我的順序模型如下:獲得中間層激活值給定的輸入例如(多個)

require 'nn' 
net = nn.Sequential() 
net:add(nn.SpatialConvolution(1, 6, 5, 5)) -- 1 input image channel, 6 output channels, 5x5 convolution kernel 
net:add(nn.ReLU())      -- non-linearity 
net:add(nn.SpatialMaxPooling(2,2,2,2))  -- A max-pooling operation that looks at 2x2 windows and finds the max. 
net:add(nn.SpatialConvolution(6, 16, 5, 5)) 
net:add(nn.ReLU())      -- non-linearity 
net:add(nn.SpatialMaxPooling(2,2,2,2)) 
net:add(nn.View(16*5*5))     -- reshapes from a 3D tensor of 16x5x5 into 1D tensor of 16*5*5 
net:add(nn.Linear(16*5*5, 120))    -- fully connected layer (matrix multiplication between input and weights) 
net:add(nn.ReLU())      -- non-linearity 
net:add(nn.Linear(120, 84)) 
net:add(nn.ReLU())      -- non-linearity 
net:add(nn.Linear(84, 10))     -- 10 is the number of outputs of the network (in this case, 10 digits) 
net:add(nn.LogSoftMax())      -- converts the output to a log-probability. Useful for classification problems 

而這裏的打印的模式:

net 
nn.Sequential { 
    [input -> (1) -> (2) -> (3) -> (4) -> (5) -> (6) -> (7) -> (8) -> (9) -> (10) -> (11) -> (12) -> (13) -> output] 
    (1): nn.SpatialConvolution(1 -> 6, 5x5) 
    (2): nn.ReLU 
    (3): nn.SpatialMaxPooling(2x2, 2,2) 
    (4): nn.SpatialConvolution(6 -> 16, 5x5) 
    (5): nn.ReLU 
    (6): nn.SpatialMaxPooling(2x2, 2,2) 
    (7): nn.View(400) 
    (8): nn.Linear(400 -> 120) 
    (9): nn.ReLU 
    (10): nn.Linear(120 -> 84) 
    (11): nn.ReLU 
    (12): nn.Linear(84 -> 10) 
    (13): nn.LogSoftMax 
} 

只需用net:forward(input)返回LogSoftMax應用後的最後一層的輸出是我不想要的。相反,我想獲得一些中間層的激活(例如模塊6)。

那麼,如何在輸入輸入時獲得每個中間層的激活?即我向網絡提供一個輸入示例,並且想要提取第六層(卷積層)的激活結果,而不僅僅是最後一層。

感謝
