<!-- Provide a quick summary of the dataset. -->

BIOMEDICA Dataset is a large-scale, deep-learning-ready biomedical dataset containing over 24M imagecaption pairs and 30M image-references from 6M unique open-source articles. Each data point is highly annotated with over 27 unique metadata fields, including article level information (e.g., license, publication title, date, PMID, keywords, MeSH terms) and coarse-grained image metadata (e.g., primary and secondary content labels
and panel type) assigned via an unsupervised algorithm and human curation by a group of seven experts (clinicians and scientists).

```BIOMEDIC\biomedica_webdataset``` is a serialized version of the BIOMEDICA dataset optimized for model development and formatted as a WebDataset for high-throughput streaming. This format provides 3x–10x higher I/O rates compared to random access memory.
