Secondary Metals Contamination Risk Model
Predicts contamination risk in recycled metal from scrap mix and impurity accumulation.
This model is a reference implementation. Industrial use requires validation on plant-specific data. Customer-specific fine-tuning remains private unless explicitly approved for publication.
Input schema
| Field | Type | Description |
|---|---|---|
| scrap_mix | object[] | Scrap grades + fractions |
| recycle_history | float[] | Accumulated impurity indicators |
Output schema
| Field | Type | Description |
|---|---|---|
| contamination_risk | float | Risk 0 to 1 |
| limiting_element | string | Element most likely to breach spec |

Reproduced the reported metric on the public split with a fixed seed. Numbers line up within noise, so it's a good baseline to build on.

Adding an uncertainty head would make this far more useful for prioritization. Happy to open a PR against the reference repo.

Validate on your data, keep the result private
Reference models are a starting point. We can fine-tune privately on plant-specific data, with customer-owned IP and no public disclosure.
