The spectral neuron - an ML primitive for scalable and interpretable models [R]

Excerpt

Worked some time ago on one of the ad teams at Yahoo, and this grew out of a question I kept returning to while there are there "simple" models that are both simple, scalable, interpretable, and controllable at the same time? Decided to explore it, first in a blog (starting here ), then in a new preprint "The Spectral Neuron", built by distilling latest blog-posts into a manuscript, I study models of the form: 𝑓(𝒙) = 𝛌ₖ(𝐀₀ + 𝚺ᵢ 𝑥ᵢ𝐀ᵢ).
