Hi there
I have tained an 1D Autoencoder NN, which you can find the its details below:
Autoencoder(
(encoder): Sequential(
(0): Conv1d(1, 5, kernel_size=(5,), stride=(2,))
(1): MaxPool1d(kernel_size=3, stride=1, padding=0, dilation=1, ceil_mode=False)
(2): ReLU(inplace=True)
(3): Conv1d(5, 10, kernel_size=(5,), stride=(2,))
(4): MaxPool1d(kernel_size=3, stride=1, padding=0, dilation=1, ceil_mode=False)
(5): ReLU(inplace=True)
(6): Conv1d(10, 15, kernel_size=(5,), stride=(2,))
(7): MaxPool1d(kernel_size=3, stride=1, padding=0, dilation=1, ceil_mode=False)
(8): ReLU(inplace=True)
(9): Conv1d(15, 20, kernel_size=(4,), stride=(1,))
(10): ReLU(inplace=True)
)
(decoder): Sequential(
(0): ConvTranspose1d(20, 15, kernel_size=(1,), stride=(4,))
(1): ReLU(inplace=True)
(2): ConvTranspose1d(15, 10, kernel_size=(2,), stride=(4,))
(3): ReLU(inplace=True)
(4): ConvTranspose1d(10, 5, kernel_size=(9,), stride=(2,))
(5): ReLU(inplace=True)
(6): ConvTranspose1d(5, 1, kernel_size=(10,), stride=(2,))
(7): ReLU(inplace=True)
)
)
my loss decrease like 1/f function however, when I feed my NN with some data, I get almost same output for different input. Has any one had any similar experience before?
I should mention that my training sample was 65536 signal each has length of 94 points.
When I said feeding my data I meant  I did this below:
for i in range(65536) :
out_put[i] = model(data_pixel2[i].unsqueeze(0))
which here data_pixel2 is my input.
Appreciate any comments.
