desi_x_ls_aion
AION-1 embeddings of DESI × Legacy Survey galaxies
95,895 galaxies, each carrying token-level AION-1 embeddings of its Legacy Survey image and DESI spectrum (embedded separately), together with its PROVABGS physical properties (redshift, stellar mass, metallicity, age, star-formation rate, …).
The embeddings are ready-made features for downstream tasks — similarity search, property regression, anomaly detection — with no GPU or raw-pixel/spectrum processing required.… See the full description on the dataset page: https://huggingface.co/datasets/EiffL/desi_x_ls_aion.gz3d-aion-replication-attempt
GalaxyZoo 3D Segmentation Benchmark
An attempted replication of the GZ3D segmentation dataset used in section 7.2.3 in the AION-1. This dataset contains volunteer segmentations for the following channels: center, star, spiral, bar. It also contains the RGB images from Legacy Survey and the tokens from the AION-1 image tokenizer of the Legacy Survey image bands. Notably, these are pre–AION-1 transformer encoder, but post image-codec encoder/quantization. The reason why it's an… See the full description on the dataset page: https://huggingface.co/datasets/astronolan/gz3d-aion-replication-attempt.mmu_ssl_legacysurvey_north_aion_demo
tokenized_demo
AION-1 tokens for hf://datasets/UniverseTBD/mmu_ssl_legacysurvey_north, produced with aion-hats. The catalog keeps the HATS layout of its source, so it can be opened with lsdb.open_catalog(...) and joined back to the source on _healpix_29/object_id, or loaded with datasets.load_dataset(...).
Tokenized columns:
image -> tok_image (LegacySurveyImage)

This dataset was created as part of the final-year project
"LLM-Powered Multi-Bias Detection in News Media with Lightweight Human-in-the-Loop Evaluation" (Academic Year 2025–26).
It contains a collection of news articles annotated across multiple types of bias. The aim is to move beyond simple left/center/right classification and capture the different ways bias can appear in news reporting.
