The Copenhagen Chemometrics Group
Let’s learn wonderful stuff
We are committed
Therefor we strive to provide high-quality resources. Our philosophy is that learning should be easy accessible and free, that’s why we offer a variety of educational content.
Our YouTube channel
Chemometrics & Machine Learning
is a great place to start you learning journey.
We regularly upload videos and webinars on a wide range of different topics.
For those who want to dive deeper
We also offer a comprehensive course, covering the use of the N-way toolbox for MATLAB.
Here you can learn how to use the N-way toolbox to analyze complex data sets and extract valuable insights.
Whether you’re a beginner or an expert
We have something for you.
The N-way course
The course covers three main multi-way models
PARAFAC and Tucker for decompositions and N-PLS for calibration/regression.
N-PLS and Tucker
Are numerically stable and can hence be used as ordinary two-way methods without considering numerical aspects such as convergence etc.
Is unique under mild conditions, but numerically it is sometimes unstable. Therefore one has to e.g. check convergence by doing multiple runs.
Otherwise the models can be interpreted and used very similar to two-way methods like PCA and PLS as will hopefully be evident from this course
