About run_cifar10

[MModerato]

After we execute the command >> run_cifar10, we get the >> MAP = 0.897373 Is this the result after reranking ? I mean the Fine-level Search. @kevinlin311tw

[kevinlin311tw]

It's coarse-level search. In MNIST and CIFAR10 experiments, we evaluate the performance with only binary codes in order to fairly compare with other hashing approaches.

name: "KevinNet_CIFAR10"
layers {
layer {
    name: "data"
    type: "data"
    source: "cifar10_train_leveldb"
    meanfile: "../../data/ilsvrc12/imagenet_mean.binaryproto"
    batchsize: 32
    cropsize: 227
    mirror: true
    det_context_pad: 16
    det_crop_mode: "warp"
    det_fg_threshold: 0.5
    det_bg_threshold: 0.5
    det_fg_fraction: 0.25
  }
  top: "data"
  top: "label"
}

In the train_CIFAR10_48.prototxt, why cropsize is 227? While the size of image in cifar is 32*32.

And when I used Netscope to view train_CIFAR10_48.prototxt, the error was reported:

Error Encountered
Uncaught TypeError: Cannot read property 'replace' of undefined


Warning
Can't infer network data shapes. Can't infer output shape of the 'undefined' layer of type 'undefined'. 
TypeError: Cannot read property 'split' of undefined

Thank you. @kevinlin311tw

We first resize images to 256x256, and then center-crop 227x227 as network input.

In the train_CIFAR10_48.prototxt, why cropsize is 227? Is the size of cifar 32*32 ?

Do you have an experiment on NUS-WIDE ? @kevinlin311tw

[kevinlin311tw]

Yes. You can take a look the extension of this work here: https://arxiv.org/abs/1507.00101v2 Our workshop version can be seen as our proposed SSDH with the hyper parameters: alpha = 1, beta = 0, gamma = 0.

Uh.. Is it correct for me to use SigmoidCrossEntropyLoss on multi-label dataset? @kevinlin311tw

[kevinlin311tw]

Oh.. I forgot that NUS-WIDE is a multi-label dataset..

Yes. You are right. Since this workshop version is trained with softmax loss, we cannot directly apply it on multi-label dataset. In this case, since the label is the n-hot vector, we should use the loss function you mentioned.

@111Moderato I also meet this mistick. Do you fix it? Error Encountered Uncaught TypeError: Cannot read property 'replace' of undefined

Warning Can't infer network data shapes. Can't infer output shape of the 'undefined' layer of type 'undefined'. TypeError: Cannot read property 'split' of undefined

[MModerato]

I forgot whether I had met the mistake. I'm using another version of Caffe, so I can run it properly after the prototxt changes

[lshignal]

@111Moderato Thanks a lot! However, this error is occurred when using Netscope to view train_CIFAR10_48.prototxt. You asked this question, but author does not answered :)

The baidu link of model and image resource is invalid, can anyone share it?
