Now that you've trained your model, you will cross-validate it against the MNIST test set, comprising 10000 28x28 images. Code has been provided to compute the accuracy (the proportion of correctly classified images) and squared error of your model. Our implementation achieved an accuracy of 92%. If your model's accuracy is significantly less (less than 90%), check your code, ensure that you are using the trained weights, and that you are training your model on the full 60000 training images. Conversely, if your accuracy is too high (99-100%), ensure that you have not accidentally trained your model on the test set as well.
