# AM12_MeltPoolKinetics

NIR melt-pool ROI frame -> thermal state: 4-way {normal,underheat,overheat,edge} (T-B2) and binary normal/anomaly (T-B1, edge excluded). Category **B**, task **T-B2 + T-B1**, in the unified Smart-Manufacturing SFT schema.

## Records

**81,099** records (train=81,099). Model input: a single NIR melt-pool ROI image (196x196), bytes embedded in the `image` column.

## Unified SFT schema (7 fields)

| field | type | meaning |
|---|---|---|
| `query` | str | the question / instruction (model input) |
| `image` | Image \| null | the INPUT image (bytes embedded) — null for tabular records |
| `annot` | str | the answer — for this dataset: the thermal-state label (text); the `task` column selects the 4-way vs binary framing |
| `reasoning` | null | no native CoT in this dataset |
| `cate` | "B" | SFT category |
| `task` | "T-B2 + T-B1" | unified task id |
| `metadata` | str (JSON) | split, provenance, units, `input`, license, and (for AM11/13) `taxonomy_note` |

## Notes

Two tasks share one dataset (distinguished by the `task` column: 45,056 T-B2 + 36,043 T-B1). Only source16 carries genuine per-frame labels. The LOBO split is kept in `metadata.lobo_split` (not an HF split). Two misfiled non-data PNGs in the source are excluded.

## Provenance & licensing

Underlying source: **MeltPoolKinetics figshare compilation, source16 = NIST AMMT; DOI 10.6084/m9.figshare.28200101**. Upstream license: **figshare compilation — per-source terms (source16 = NIST AMMT); verify per source**.
Converted read-only into the unified schema; conversion + publish scripts live in
[`AI4Manufacturing/forge_model`](https://github.com/AI4Manufacturing/forge_model)
(`AM12_MeltPoolKinetics/` + `publish/push_am_to_hf.py`). Access is **gated (manual approval)**; clear the
upstream licence before any onward redistribution.
