Me, Myself, and AI Industrial AI for the Physical World: Siemens’s Peter Koerte
65 snips
Apr 21, 2026 Peter Koerte, Siemens chief strategy and technology officer focused on industrial AI and sustainable tech. He describes how AI quietly upgrades factories, grids, trains, and buildings. He contrasts industrial needs for near-perfect accuracy and proprietary domain data. He discusses data-sharing, predictive maintenance like train-door forecasts, simulation acceleration with partners, and workflow and workforce transformation.

Episode notes
Industrial Models Demand Near Perfect Accuracy
- Industrial models require far higher accuracy and different data types than consumer models.
- Siemens targets 99%+ reliability and trains on time series, CAD, simulation, and domain-specific sensor data rather than web text or LLM corpora.
Start With Industry Ontologies Before Modeling
- Build around domain ontologies and specific semantics for each industry before modeling.
- In buildings use energy and temperature ontologies; in production focus on quality and throughput parameters tied to domain know-how.
Train Doors Are The Operational Bottleneck
- Trains illustrate domain insight: doors, not brakes, are the most critical operational component.
- Siemens uses motor voltage profiles to predict door failures up to 10 days ahead so operators can preemptively fix them.
