Augmented Models

Picture a situation where a company has a spectrometer and model that is performing well in a quality control setting. The company wants to set up a second spectrometer for another line or another location. Normally, we need to wait until enough spectra and reference values are available to be able to build a competent model, which can take months, even a year. In Ai-Metrix, a customer can choose to jointly model a data-rich spectrometer with a data poor instrument. If Ai-Metrix sees a discrepancy in data amounts, it clicks in a new set of optimization parameters and builds an augmented model that should be available within days. The model will not be as good as a well-populated calibration, but the system would then dial itself in as more data becomes available. Because Ai-Metrix does not care how many models a user creates, the marginal cost for this series of model updates is essentially zero. And you can put the spectrometer to use right away.

Industrial Grade Chemometrics: from Laboratory to Process Implementation
Presented by:
Brian Rohrback, President, Infometrix, Inc.
Abstract:
The use of multivariate statistics, whether termed chemometrics or machine learning or (fill in the blank), is critical for industry to move from human-centered processing to more automated, objectively reliable processes. In the laboratory world, we seek to discover new routes for solving problems that will give us better solutions than previous methods. And this largely university-based effort is critical for enabling improvements in product manufacturing and the quality control process that accompanies it. But, given academia’s limited access to commercial application samples, most chemometrics publications deal only with the method development side of a given problem. If we are going to benefit a manufacturing organization, an industry, or especially society, the emphasis needs to be on the shift from this laboratory origin to a solid process implementation. Anything useful we devise must ultimately get used; if we fail to integrate proven technology into the day-to-day, the development process is simply an expense. The experience through the now five decades of implementing multivariate solutions has identified some steps, some barriers, and some low-hanging fruit. How do we succeed in pushing new technology the last mile?
