Chemometrics without Equations (or Hardly Any)
February 13, 2024 - February 15, 2024
Eigenvector Research, Inc. is pleased to bring you Chemometrics without Equations (or Hardly Any), an online instructor-led live short course. This easily accessible introductory course covers the basics of chemometrics: the application of modern multivariate and machine learning methods to chemical data. In this hands-on course you will be introduced to the most commonly used chemometric methods and learn how to interpret and apply them for best results.

Target Audience
Chemometrics without Equations was developed for chemists and bio-scientists who need to analyze multivariate chemical data and for those who manage these staff members. It covers the basics of pattern recognition, quantitative (regression) and qualitative (classification) models. Additional sections discuss how to improve models through advanced data preprocessing and variable selection. The course is relevant in a large number of analytical applications including
- Process Analysis, e.g. pharmaceutical, food & beverage, and chemical process industries.
- Analytical Chemistry, e.g. QC labs, forensic investigations, etc.
- Sensory and Consumer Science
- Medical Devices
- Metabolomics, genomics, etc.
Course Description
Chemometrics Without Equations (or Hardly Any) is designed for those who wish to explore the problem solving power of machine learning tools but are discouraged by the high level of mathematics found in many software manuals and texts. Course emphasis is on proper development and interpretation of chemometric methods as applied to real-life problems. The objective is to teach in the simplest way possible so that participants will be better chemical data science practitioners and managers.
Chemometrics without Equations starts by introducing one of the most important methods in data science, Principal Components Analysis (PCA). PCA is used in a myriad of applications for exploratory data analysis/pattern recognition. The course continues with regression methods including Classical Least Squares (CLS) and the now ubiquitous Partial Least Squares regression (PLS). It is then shown how these methods are adapted for sample classification in SIMCA and PLS Discriminant Analysis (PLS-DA). The course concludes with sections on how models can be improved with advanced preprocessing methods and variable selection.
This course will be delivered via WebEx webinar in three segments of three and a half hours each. The course material is based on our popular Chemometrics without Equations and Advanced Chemometrics without Equations courses that have been popular at many conferences including EAS and SCIX. The course will be recorded, so if you miss something or want to review you will be able to access the recording shortly after each class.
The course will include many follow-along examples and several homework problems. In order to take advantage of these, participants should equip their computers with current versions of our MATLAB based software PLS_Toolbox or our stand-alone Solo software (available for Windows, MacOS and Linux). Demo copies will work just fine for the course. Users with Eigenvector accounts can download free demos. If you don’t have an account, start by creating one.
About the Instructors
The course will be led by Eigenvector President and PLS_Toolbox creator Barry M. Wise along with Eigenvector Vice-president Neal B. Gallagher. They will be assisted by members of the Eigenvector scientific and software development team. Drs. Wise and Gallagher have delivered over 200 chemometrics courses at scientific conferences, on-site for companies and at our popular Eigenvector University each year in Seattle.
