XYSquares

Synthetic dataset intended for benchmarking disentanglement frameworks.

XYSquares is adversarial in nature; the distance between any two observations in the dataset is constant when measured using a pixel-wise distance function. It is usually impossible for VAE frameworks that use pixel-wise losses to disentangle this dataset.

The dataset is constructed from 3 non-overlapping red, green and blue squares that are each $8\times8$ pixels in size. Each square can move along the $x$ and $y$ coordinates of an $8\times8$ grid. The resulting images are $64\times64$ pixels in size. With this construction the dataset has a total of 8 ground-truth factors for a total of $8^6 = 262144$ observations.
