## MNIST Image Data

Chris Hua / `chua@wharton.upenn.edu`

Produces the MNIST image recognition data as dataframes in R. Look at the vignettes for examples of how to work with the MNIST data, using `tensorflow` and `neuralnet` packages.

## Installation 

```{r, eval = F}
install.packages("devtools")
devtools::install_github("stillmatic/MNIST")
```

## Usage

Data is exported as `MNIST::mnist_train` and `MNIST::mnist_test`.

```{r}
MNIST::mnist_train %>% dim
```

```{r}
table(MNIST::mnist_test$y)
```

```{r}
MNIST::show_digit(MNIST::mnist_train[42,])
```
