Sentinel-2 LeJEPA Preset-Biased (Small) A small, preset-biased Sentinel-2 L2A chip dataset curated for self-supervised pretraining of a LeJEPA ResNet-18 encoder. Built as a reproducibility artifact for the Sentinel Change Explorer proof-of-concept foundation-model change-detection feature. This is a proof of concept, not a general-purpose EO pretraining corpus. It is intentionally tiny (~thousands of chips) and biased toward the five demo AOIs the Sentinel Change Explorer app… See the full description on the dataset page: https://huggingface.co/datasets/falafel-hockey/sentinel2-lejepa-global-diverse-256.
