About
About the course
Course content
This course introduces chemometric methods for data analysis and experimental design, emphasising applications in biology, biotechnology, chemistry, material science, and physics. You will learn to design efficient experiments, prepare data for analysis, construct models to reveal underlying relationships in data and extract meaningful information from complex datasets.
The following topics are covered:
- Preprocessing (e.g., numerical differentiation and integration, smoothing, and frequency analysis)
- The design of experiments (e.g., full and fractional factorial design)
- Regression (e.g., linear and nonlinear least squares) and machine learning techniques for unsupervised (e.g., cluster analysis) and supervised problems (e.g., classification)
- Model validation (e.g., using test sets, cross-validation, and bootstrapping)
- Dimensionality reduction and latent variable methods to extract meaningful information from complex datasets (e.g., principal component analysis and partial least squares regression)
Learning outcome
Knowledge
After completing the course, the student can:
- Explain the principles of experimental design, including factorial designs, and how data from such designs are analyzed
- Explain the purpose and use case of various preprocessing methods
- Select appropriate chemometric techniques based on an evaluation of data analysis needs
- Describe chemometric methods for supervised and unsupervised learning (e.g., regression, principal component analysis) and provide examples of their real-world applications.
- Analyze and interpret the results obtained from chemometric methods.
- Explain how validation methods are used to evaluate the performance and accuracy of models
Skills
After completing the course, the student can:
- Reduce the dimensionality of complex datasets to extract meaningful information
- Design and analyze experiments using techniques from the design of experiments
- Prepare data for analysis using appropriate data preprocessing techniques, including cleaning, transformation, and scaling
- Perform principal component analysis and cluster analysis to explore and interpret complex datasets
- Build regression models for prediction and data analysis
- Build classification models for prediction and data categorization
- Evaluate model performance using validation techniques such as test sets and cross-validation.
General knowledge
After completing the course, the student can:
- Communicate complex chemometric results effectively, using clear and concise language and visualizations
- Apply Python programming to solve real-world chemometric problems, including data import, preprocessing, analysis, and visualization
Learning methods and activities
- Lectures.
- Exercises.
- Project work.
The project work is a mandatory independent research project carried out by the candidate. In this project, the candidate will carry out a chemometric analysis on a topic adapted to the research interests of the candidate.
The results from the project are to be presented in a lecture (lasting about 30 minutes) where the candidate may be asked questions (or given comments) about their work. This lecture accounts for 20% of the final grade in the course.
Information about the start of lectures and compulsory activities will be given via Blackboard.
Expected work load in the course is 200 hours.
Compulsory assignments
- Project work
Further on evaluation
The final assessment in the course is made on the basis of the presentation of the project work (20%) and the oral exam (80%).
Recommended previous knowledge
Basic knowledge of mathematics (especially linear algebra), statistics, and chemistry (or a similar natural science field).
Course materials
The course material will be announced at the beginning of the course.
