\section{Exercise Variant 2}
Use \href{https://pytorch.org/vision/stable/generated/torchvision.datasets.MNIST.html#torchvision.datasets.MNIST}{MIST} dataset. Evaluate at least 3 different numbers/values/types of:
\begin{itemize}
    \item learning rate
    \item mini-batch size (including batch containing only 1 example)
    \item number of hidden layers (including 0 hidden layers - linear model)
    \item width (number of neurons in hidden layers)
    \item optimizer type (e.g., SGD, SGD with momentum, Adam)
\end{itemize}
