A Technical Exchange for Metal AI Builders
Built for metallurgists, process engineers, researchers, data scientists, plant teams, students, and AI builders. Trending discussions, open research questions, dataset requests, and monthly challenges, all organized by metal, process, and topic.
Monthly challenge
July: improve the rare earth recovery baseline
Beat the reference MAE on the open split. Reference and research submissions welcome.
- Open research question6123
Which signals best separate cycle-time drift from genuine product mix change?
On the synthetic set, per-product baselining beat a global standard for isolating true drift. Curious how others handle mix-driven variation on real lines.

Looking for anonymized packaging-line speed logs with micro-stop labels
Happy to contribute synthetic augmentation if anyone has non-confidential line-speed traces paired with micro-stop events for FMCG lines.

Proposal: a shared material-value economics benchmark across industries
We keep re-deriving material-minute value per plant. A shared, range-based benchmark with documented assumptions would make comparisons honest. Draft attached.

Normalizing bottleneck-rate features across products and shifts
Relative-to-best-rate features transfer across conditions; absolute rates don't. Anyone normalized constraint features across a mixed product slate?

Do you count lab-hold time as downtime, or is it invisible on your OEE?
Most sites we see never book release-decision waiting as a loss. How are you surfacing it without turning it into a blame metric?

- Open research question7231
How far do tabular baselines get us before sequence models pay off?
Across the Material Value Leakage detection tasks, gradient boosting is within a point or two of fancier models. Where does temporal structure actually earn its keep?
