Pca Graph. This video introduces principal component analysis or pca which is new in prism 9. It s a powerful tool used for exploratory analyses with large datasets.
Follow along as we motivate pca with an example in prism. This graph pca has some interesting links with spectral graph theory in particular spectral clustering. Here we will see the implementation of pca using the scikit learn python library.
We finally define the principal components analysis pca of a graph as the subspace projection that preserves as much variance as possible in terms of the ectd.
Because this library already implements pca for us and is a way to generate the scree plot. Here we will see the implementation of pca using the scikit learn python library.
