| MNIST dataset adapted to a text-based representation. | |
| Modified images to be ~1/4 the original area. | |
| Done by taking a max pool. | |
| This allows testing interpolation quality for Transformer-VAEs. | |
| System is heavily inspired by Matthew Rayfield's work https://youtu.be/Z9K3cwSL6uM | |
| Works by quantising each MNIST pixel into one of 64 characters. | |
| Every sample has an up & down version to encourage the model to learn rotation invarient features. | |
| Use `.array_to_text(` and `.text_to_array(` methods to test your generated data. | |
| Data format: | |
| - text: (16 x 14 tokens, 224 tokens total): Textual representation of MNIST digit, for example: | |
| ``` | |
| 00 down ! ! ! ! ! ! ! ! ! ! ! ! ! ! | |
| 01 down ! ! ! ! ! ! ! ! ! ! ! ! ! ! | |
