M3LEO-miniset/china

China AOI

Randomly sampled 5000 data tiles (3000 for training, and 1000 for validation and testing). Occasionally, not all tiles were available for all datasets. We include a detailed breakdown of the number of chips per dataset below.

We provide '.csv' files with predefined train (blue), test (orange) and validation (green) splits that can be used for repeatability and comparability of experiments. 60% of tiles are allocated for training, 20% for validation, and 20% for testing.
