Run the code from the book, A Computational Approach to Statistical Learning, from Chapter $8$ casl Chapter $8.$ This example is related to the EMNIST dataset. Read the sample chapter Chapter $8.$ Use Meld to merge the changes from ver$01$ into ver$02$ of the R Notebook. Your assignment is to run the code in ver$02$ and write clear explanations above each R code chunk. Be sure to explain what a Feed$-$forward Neural Network is and what the Convolutional layers are.
