LSV PMD Split Benchmark Dataset

PMD split clips provide short pipetting examples for correct-vs-mistake and mistake-type evaluation.

Layout

• correct/: split correct demonstration clips
• incorrect/: split mistake demonstration clips
• pmd.parquet: split-clip benchmark manifest

Counts

• split clips: 246
• by label: {'correct': 15, 'incorrect': 231}
• by mistake_type: {'early_release': 45, 'none': 15, 'reuse_same_media': 27, 'reuse_same_tip': 4, 'reuse_tip': 53, 'surface_contamination': 44, 'wrong_tip_for_pipette': 58}

Review Flags

• needs_review clips: 6

The needs_review and notes columns preserve human review notes for a small number of clips whose source labels required normalization.

Evaluation

Use pmd/pmd.parquet with lsvbench/tasks/prompts/pmd.md or the pmd task in lsvbench.

The prompt preserves detailed answer options (ERROR_REUSE, ERROR_SURFACE, ERROR_RELEASE, ERROR_INSTALL, ERROR_OTHER) for compatibility with existing model outputs. The public benchmark report collapses all non-CORRECT options into binary ERROR and reports only Error Detection metrics.
