metmuseum/openaccess-embeddings-apple-mobileclip

Image embeddings for every public-domain artwork in metmuseum/openaccess, produced by apple/MobileCLIP-S2-OpenCLIP.

Column	Type	Notes
`objectID`	int64	Primary key — matches `objectID` in `metmuseum/openaccess`
`embedding`	list<float32>	L2-normalised, dim = 512
`model`	string	Source model id
`dim`	int32	Embedding dimension

Image bytes are not stored here; join against the main dataset to recover them.

Embedding spec: dim=512, expected image size=256px.

Joining with the main dataset

from datasets import load_dataset

meta = load_dataset("metmuseum/openaccess", split="train")
emb  = load_dataset("metmuseum/openaccess-embeddings-apple-mobileclip", split="train")

# Build an objectID -> embedding lookup, then attach to the metadata rows.
lookup = {r["objectID"]: r["embedding"] for r in emb}
joined = meta.map(lambda r: {"embedding": lookup.get(r["objectID"])})
print(joined[0].keys())

Nearest-neighbour example

import numpy as np
from datasets import load_dataset

emb = load_dataset("metmuseum/openaccess-embeddings-apple-mobileclip", split="train")
ids = np.array(emb["objectID"])
mat = np.array(emb["embedding"], dtype=np.float32)  # already L2-normalised

query = mat[0]
scores = mat @ query
top = np.argsort(-scores)[:10]
print(list(zip(ids[top].tolist(), scores[top].tolist())))
