SEARCHAccelerating Model Development and Generating Ensembles with Diviner
June 16, 2025
Keflavik, Iceland
Eigenvector Research, Inc. is pleased to offer Accelerating Model Development and Generating Ensembles with Diviner, a live, in-person short course showing how to use Diviner tools in Eigenvector’s PLS_Toolbox and Solo. This course will be held at the 19th Scandinavian Symposium on Chemometrics (SSC-2025) conference in Keflavik, Iceland.
Complete information about the course can be found by following the links below.
Target Audience
Accelerating Model Development and Generating Ensembles with Diviner is aimed at spectroscopists and other scientists who need to generate quality calibration models in limited time.
Course Description
Diviner, our semi-automated machine learning tool (semi-autoML) for developing calibration models, was introduced with PLS_Toolbox and Solo 9.5 in 2024. (Divine—to discover or locate something by intuition, insight or supernatural means.) Unlike conventional autoML methods that yield a single optimal model, our approach creates a diverse family of models and ranks them by their cross-validation performance, degree of overfitting, and prediction error on validation sets. These models may be further refined to produce a single “optimal” model. Alternately, a group of candidate models can be used to create an ensemble model that harnesses the diversity of the candidate models. These models are combined using voting regression. This leverages the complementary strengths and reduces individual model weaknesses, enhancing overall predictive accuracy and robustness. In this hands-on class participants will learn to use Diviner to create single models and ensembles.
In order to take advantage of these hands-on examples participants should equip their computers with current versions of Solo or PLS_Toolbox (and MATLAB) installed. Demo copies will work just fine. Users with Eigenvector accounts can download free demos. If you don’t have an account, start by creating one.
About the Instructor
The course will be led by Eigenvector President and PLS_Toolbox creator Barry M. Wise. Barry has delivered hundreds of chemometrics courses at scientific conferences, on-site for companies, on-line and at our popular Eigenvector University each year in Seattle.
