- Attempts to load the MNIST dataset from the hard drive. This is the dataset |
|
of handwritten digits available from http://yann.lecun.com/exdb/mnist/. In |
|
particular, the 4 files comprising the MNIST dataset should be present in the |
|
folder indicated by folder_name. These four files are: |
|
- train-images-idx3-ubyte |
|
- train-labels-idx1-ubyte |
|
- t10k-images-idx3-ubyte |
|
- t10k-labels-idx1-ubyte |
|
- #training_images == The 60,000 training images from the dataset. |
|
- #training_labels == The labels for the contents of #training_images. |
|
I.e. #training_labels[i] is the label of #training_images[i]. |
|
- #testing_images == The 10,000 testing images from the dataset. |
|
- #testing_labels == The labels for the contents of #testing_images. |
|
I.e. #testing_labels[i] is the label of #testing_images[i]. |
|
throws |
|
- dlib::error if some problem prevents us from loading the data or the files |
|
can't be found. |
