machine learning phenomena through minimalist examples

  • at interpolation, generalization is distance to Bayes

    in the same setup as the previous post, the generalization gap turns out to have a simple analytical form: Bayes error plus a disagreement term, computable in one dimension

  • same model, same optimizer -- different generalization

    a minimalist reproduction of why generalization cannot be understood without looking at the data
