mnist-dataset

✍️ Yann LeCun's MNIST handwritten digit dataset, made available to Node.js. This library contains all of the utilities you need to download and parse the raw unfiltered dataset, which is expressed as JSON arrays. It uses fs to cache to your system's tmpdir() so that you don't have to keep downloading the dataset between successive executions of your software.

🚀 Getting Started

Using npm:

npm install --save mnist-dataset

Using yarn:

yarn add mnist-dataset

✍️ Usage

import { cache, trainingImagesUrl, trainingLabelsUrl } from 'mnist-dataset';

(
  async () => {
    const trainingImages = await cache(trainingImagesUrl); // [[Number]] (i.e. [[0, 0, 0, ...], [0, 0, 0, ...], ...])
    const trainingLabels = await cache(trainingLabelsUrl); // [[Number]] (i.e. [[7], [2], ...])

    const toString = e =>
      [...Array(28)]
        .map((_, i) =>
          [...Array(28)].map((_, j) => (e[i * 28 + j] > 128 ? "#" : " ")).join("")
        )
        .join("\n");

    const [number7] = trainingImages;
    console.log(toString(number7));
  }
)();
