KnowItAll中的化学计量学模型

Chemometric Models in KnowItAll ®

Through collaboration with Infometrix, Inc., the premier chemometrics software company, chemometric models built with Infometrix' Pirouette ® software  can  now  be  imported  directly  into  Bio-Rad  Laboratories'  KnowItAll ® platform.  These  models  can  be  used  to  make  property predictions based on spectral, chromatographic, or other profile data. They can predict a range of properties including biological, chemical, and manufacturing process-related endpoints.

All model types currently supported in Pirouette are supported in the KnowItAll system, including classification models (both single class and multiple class) and regression models (single property and multiple property). Prediction confidence estimates are also supported.

Typical user workflow...

•  User collects data from the KnowItAll system, exports spectral or chromatographic information with observed property values into the Pirouette .DAT format.

•  User then opens the .DAT file in Pirouette, creates model(s), and exports the model(s) in .MOD format.

•  Model(s) are configured in the KnowItAll system before they are deployed the first time, as shown in the following example below.

• The configured models can then be used repeatedly in KnowItAll as property predictors.
