188-region

Region-conditioned defect QA on mobile phone screen — 3653 items, derived deterministically from the binary segmentation masks of AI4Manufacturing/188. Exact-match gradable → SFT and RLVR-ready.

Task

"A region is indicated — what defect, if any, is there?" One item per defect instance (3050 positives: scratch 1372, stain 1120, oil 558) plus 603 clean-region negatives teaching rejection (every good record + ~half of defective records). The region is conveyed in one of two modes (metadata.region_mode; overlay 1781 / bbox_text 1872):

  • overlay — a red rectangular ring drawn on the image around the region.
  • bbox_text — the raw image plus the region as a pixel box [x, y, w, h] in the query text.

Clean boxes sample size AND position from the emitted positive population, so box geometry separates nothing. Gold = the type name (closed list) or no defect. Verified: zero defect pixels inside any clean box; positive gold matches the source type on every row.

Provenance

Built deterministically (no LLM/teacher; reasoning is null) from AI4Manufacturing/188 — MSD mobile-phone-screen inspection — 1,220 photos, 3 defect types (oil, scratch, stain) + good; each anomalous image has a paired binary pixel segmentation mask (binarized from the palette mask at index>0 (the source encodes defect TYPE in the palette index, so LOCATION comes from the mask and TYPE from metadata)). Generator: annotate/188/build_188_derived.py in forge_model; machine gates annotate/188/verify_188.py (all green at build: boxes/gold re-derived byte-identical, clean regions contain zero defect pixels, mcq gold = the true panel, no leaked-artifact vocabulary, image set sha256-disjoint from all other cached AI4Manufacturing datasets).

Resolution. Images are native 1920×1080 (not downscaled — preserves thin scratches); all coordinates live in that pixel space (see metadata.image_wh).

Query diversity. query is drawn from a fixed pool of surface variants (paraphrases preserving the task + answer format), selected by an independent per-record hash; a machine gate confirms no template correlates with the gold.

The repository name is an internal task code (the source dataset's code is 188).
