 ### Dataset Description
 
-This dataset comprises a curated PD12M image collection, refined by filtering for active image links. EXIF data was extracted, and images underwent preprocessing and feature extraction using SigLIP2. All vector embeddings are normalized 16-bit half-precision vectors optimized for L2 indexing with [vectorchord](https://github.com/tensorchord/vectorchord).
