Part of MulTaBench, a benchmark for multimodal tabular learning.
Frozen image embeddings of the MulTaBench datasets, cached so leaderboard runs don't re-encode them. Each
<dataset>/embeddings.npz maps every distinct input, exactly as the encoder got it, to its raw encoder output (PCA is
fitted per run, on the training rows); meta.json holds the dataset's rows and columns, the encoding time per feature
and the hardware. See Cached embeddings.
