You attended my SHAP tutorial?

Thank you for coming. The tutorial page links to the slides, the course notes and the code.

This tutorial is a short version of what I do with teams: hands-on training in machine learning with R, in English or French.

Training

Hands-on courses for teams

My courses run in small groups. They are taught in French, and in English on request for teams.

  • Machine learning with R: first steps. From core concepts to random forests: build your first models.
  • Advanced machine learning with R and tidymodels. Deep learning, tuning and explainability. Coming soon.
  • Multivariate statistics. PCA, correspondence analysis, clustering. Coming soon.
  • Custom training. A programme built around your needs.

What participants say

Joe Senior Research Associate

Thelma’s presentation on machine learning made the whole process feel far more straightforward than I’d expected. The way they explained how to choose an appropriate AI model, such as decision trees, random forests, and k-nearest neighbours, made it feel intuitive rather than abstract. They have a very clear, methodical way of teaching that makes complex ideas easy to follow without oversimplifying them. I came away with a much stronger understanding of how to approach model selection in practice.

Claire Research Scientist, National Oceanography Centre

Thelma is a very clear presenter and teacher who is very friendly, calm and patient. They are very knowledgeable in R coding and machine learning methods. Most importantly, they explain when to use certain methods over others and why, with the why driven by the topic of work.

Consulting

Concrete, reproducible, documented.

You have data, questions and constraints. I support your data science projects with clean, reproducible source code, complete technical documentation and skills transfer, so your team can carry on without me.
