Applications and problems

Soft sensors and Virtual Analyzers

A soft sensor estimates a property that is not continuously available from variables measured more frequently. To be useful it must respect real process time, laboratory delay and cases that lie outside the learned domain.

What matters

The problem comes before the model.

  • Features that were genuinely available at prediction time, without future leakage.
  • Alignment with delayed and noisy laboratory assays.
  • OOD detection and the ability to abstain instead of always producing a number.

Lab Intelligence approach

Sources, assumptions, checks, versions, metrics and limitations remain visible. A more complex technique is used only when it adds value over an understandable baseline.
