What model to train to restore MNIST test dataset

I came across this problem, and am not sure where to start. What model would work best for this problem and why? Imagine the digits in the test set of the MNIST dataset (http://yann.lecun.com/exdb/...

How can a neural network distinguish a rotated 6 and 9 digits?

Rotated MNIST is a popular dataset for benchmarking models equivariant to rotations on $\mathbb{R}^2$, described by $SO(2)$ group or its discrete subgroups like $\mathbb{Z}^{n}$: Group equivariant ...

Can neural networks learn noise?

I'm interested in the following graphs. A neural network was trained to recognise digits from the MNIST dataset and then the labels were randomly shuffled and the following behaviour was observed. ...

MNIST with fewer pixels? [closed]

MNIST images are 28x28 pixels. Perhaps a silly question: is there anything like MNIST, but whose images have fewer pixels?

Why would my neural network have either an accuracy of 90% or 10% on the validation data, given a random initialization?

I'm making a custom neural network framework (in C++, if that is of any help). When I train the model on MNIST, depending on how happy the network is feeling, it'll give me either 90%+ accuracy, or ...

Why does the VAE using a KL-divergence with a non-standard mean does not produce good images?

I know I can make a VAE do generation with a mean of 0 and std-dev of 1. I tested it with the following loss function: ...

Statistical method for selecting features for classification

I'm working on a classifier for the famous MNIST handwritten data set. I want to create a few features on my own, and I want to be able to estimate which feature might perform better before actually ...

Is there a way to reduce the RMSE error when training a neural network to recognise MNIST digits using ANFIS?

I wanted to build a digit recognition neural network using MATLAB ANFIS kit. I started by using the MNIST database and I figured out it's almost impossible to classify 784 dimension data using ANFIS. ...
