🚧 This website is under construction. Pages will keep being updated in the next few weeks!
Welcome to the seventh week of this course!
This week, we start our exploration of unsupervised learning:
- we discover what differentiates it from supervised learning and in which cases it is used
- we learn about the first family of unsupervised learning techniques: dimensionality reduction. We’ll explain what dimensionality reduction is about and what it is used for before introducing the most common and arguably the most well-known dimensionality reduction algorithm by far: PCA (Principal Component Analysis). We also have a look at other linear dimensionality reduction algorithms (i.e MCA and FAMD) as well as non-linear dimensionality reduction algorithms: UMAP and auto-encoders.
