# The MNIST-1D Dataset

Most machine learning models get around the same ~99% test accuracy on MNIST. Our dataset, MNIST-1D, is 100x smaller (default sample size: 4000+1000; dimensionality: 40) and does a better job of separating between models with/without nonlinearity and models with/without spatial inductive biases.

## Dataset Creation

This version of the dataset was created by using the pickle file provided by the dataset authors in the original repository: [mnist1d_data.pkl](https://github.com/greydanus/mnist1d/blob/master/mnist1d_data.pkl) and was generated like follows:

```python
import sys ; sys.path.append('..')  # useful if you're running locally
import mnist1d
from datasets import Dataset, DatasetDict

# Load the data using the mnist1d library
args = mnist1d.get_dataset_args()
data = mnist1d.get_dataset(args, path='./mnist1d_data.pkl', download=True) # This is the default setting

# Load the data into a Hugging Face dataset and push it to the hub
train = Dataset.from_dict({"x": data["x"], "y":data["y"]})
test = Dataset.from_dict({"x": data["x_test"], "y":data["y_test"]})
DatasetDict({"train":train, "test":test}).push_to_hub("christopher/mnist1d")
```

## Dataset Usage

using the `datasets` library:

```python
from datasets import load_dataset
train = load_dataset("christopher/mnist1d", split="train")
test = load_dataset("christopher/mnist1d", split="test")
all = load_dataset("christopher/mnist1d", split="train+test")
```
