hello , I can not download pretrained model , can you fix it?

Unfortunately, my server cannot run VGG network because there are too many network parameters. So I want to use CNN-F (Alexnet) instead of VGG. Two Global_Average_Pooling methods are used in the VGG network and the full connection layer is removed. Can you tell me how to modify in CNN-F(AlexNet) network?
thanks!

It is said, "S_b in the N-PQ loss (i.e., Equation 2 in the paper) denotes a cosine similarity between b-th feature vector and every quantized vector". According to the code, this is implemented by matrix multiplication:

So, this is actually not the cosine similarity, but just an ordinary inner product. The product does not reflect a similarity measure in the conventional sense, and may affect the results.

1.hello, what are the specific mean and variance in nuswide?

def color_preprocessing(x_):
#Normalize with mean and std of source data
x_ = x_.astype('float32')
x_[:, :, :, 0] = (x_[:, :, :, 0] - 125.642) / 63.01
x_[:, :, :, 1] = (x_[:, :, :, 1] - 123.738) / 62.157
x_[:, :, :, 2] = (x_[:, :, :, 2] - 114.46) / 66.94
return x_

2. In nuswide, can specific training lists and test lists be provided?

Good work and thanks！

If you have the code of the pytorch version, please share it！

Nice work and Thanks!
Meanwhile the downloaded mat for CIFAR10 can't be loaded correctly.

Hi,
There are a total of 27000 images in the NUS dataset. I chose the 21 most popular classes, with a total of 195834 images. But, the experimental results are much worse than those in the paper. Can you provide the name list and label of train and test image database.

The experimental results obtained by using Alexnet or VGG network on experimental protocol 2 ？

I find the program is computing distance based on table Z.
but this way is hard to applying my own experiments since I want to extract the hash codes for my custom dataset. Then I can plot some precision recall curve and so on.
could you add the way of extracting hash codes for some dataset?

Hello, I was that in the issues the problem about pretrained model is mentioned and then closed by fixing the issue. But the link for the pretrained model weights is still broken. Thanks
