A Solution Template for Soft Sensor Modeling on Azure Part 2

In the first part, we explored what a soft sensor is, the use case, dataset, common approaches and major steps usually needed to model soft sensors. In this second part, we will explore how to use Microsoft''s Azure Data and AI platforms to process and model the data at scale, in an automated fashion.

Soft Sensors for Bioprocess Monitoring

Modeldriven soft sensors can be based on mass or energy balances — on firstprinciple approaches. They incorporate process knowledge, and unlike datadriven models, they are a more suitable match for extrapolation. But of course, they also have drawbacks. For example, the biggest problem is that they assume a mechanistic trend.
