This question is from an old exam.

I am really stuck and cannot imagine how this could be classified successfully.

It seems like the two classes are inseparable.

I asked myself: would LDA or PCA, as an initial step, work here? I don’t think so.

So if I was to answer the question right now, I would say we need a Deep NN and draw a freeline approximation.

Any hint, help or answer appreciated a lot!
