OPS-Eval: Leakage-Resistant Evaluation for Optical Pooled Screens Benchmark artifacts for evaluating representation learning on pooled CRISPR microscopy data. This dataset accompanies a submission to the NeurIPS 2026 Evaluations and Datasets Track. Contents Directory/File Description Size montages/ Per-gene montage images (4 channels x 2 phases, ~10 PNGs per gene) ~66 GB cell_embeddings/ Pre-extracted 512-dim cell embeddings per sgRNA (.npz) ~15 GB… See the full description on the dataset page: https://huggingface.co/datasets/cspeters119/ops-eval.
