Description

We currently have 115 attributes for every changeset. It is practically impossible how all these features look like. But, we could use techniques of Dimensionality reduction and project them into 2 dimensions.

We have powerful Principal component analysis (PCA) as part of `scikit-learn`:

Research direction

Start by locating where the 115 changeset attributes are assembled and how the feature data is exposed to notebooks. Read the scikit-learn decomposition documentation, then determine how a two-dimensional PCA projection should be produced and presented. Done means the changesets can be projected into two dimensions, with a reproducible notebook or entry point showing the result.
