Abstract

Clark & Thornton's type-1/2 distinction is not well-defined. The classes of type-1 and type-2 problems are too broad: many noncomputable functions are type-1 and type-2 learnable. They are also too narrow: trivial functions, such as identity, are neither type-1 nor type-2 learnable. Moreover, the scope of type-1 and type-2 problems appears to be equivalent. Overall, this distinction does not appear useful for machine learning or cognitive science.
