Prompt a dataset for an educational article

Question

Mathematics

habrahabr.ru/post/172043/ A data set is required to continue this post. I want to talk about the method of principal components. The requirements are as follows: from several dozen objects, and that there are many parameters, and that they are strongly correlated with each other. An example is a database of the shape and size of faces. Nothing like this is available for free.

Answer 1

Classic:
- example for PCA with faces: scikit-learn.org/dev/auto_examples/decomposition/plot_faces_decomposition.html#example-decomposition-plot-faces-decomposition-py (about Olivetti Faces: scikit-learn.org/dev/datasets /olivetti_faces.html#olivetti-faces )
- they also apply to Iris PCA ( scikit-learn.org/dev/auto_examples/decomposition/plot_pca_vs_lda.html , en.wikipedia.org/wiki/Iris_flower_data_set )
