Nonlinear Model Support Added to Model_Exporter

Model_Exporter is EVRI’s software for turning multivariate/chemometric models into formats which can be compiled into online applications. It offers an alternative to our stand-alone prediction engine Solo_Predictor. Model_Exporter allows users of our MATLABĀ® based PLS_Toolbox and stand-alone Solo to easily create a numerical recipes of their models. These recipes give the step by step procedure that take a measurement and calculate the desired outputs, such as concentration, class assignment, prediction diagnostics, etc. This includes applying all preprocessing steps along with the model (PCA, PLS, PLS-DA etc.) itself. When Model_Exporter is installed, models can be exported into predictor files in a variety of formats via the file menu in the Analysis window as shown below.

Model_Exporter also includes two versions of the freely-distributable Model_Interpreter. Either the C# or Java version of the Model_Interpreter can be used by any 3rd party program to add the ability to parse an exported model in XML format. Simply point the interpreter at an XML exported model and supply the data from which to make a prediction. The interpreter applies the model and returns the results. Model_Interpreter has no licensing fees and is appropriate for use on standard processors and operating systems or on handheld devices run by reduced instruction set processors (e.g. ARM). Your application doesn’t need to know anything about the preprocessing or model being used.

Version 3.0 of Model_Exporter was released in early October along with its associated stand-alone Solo+Model_Exporter version 7.9. This release includes support for Support Vector Machine (SVM) regression and classification models as well as Artificial Neural Network (ANN) regression models.

These changes represent a significant addition to Model_Exporter making it even more unique in the chemometrics world. No other chemometric modeling product offers anything as transparent, flexible or unencumbered by licensing. You can get more info about Model_Exporter by consulting the Release Notes and the Model_Exporter Wiki page.

Users with current maintenance can access these versions now from their account. If expired, maintenance can be renewed through the “Purchase” tab.
