would you not expect your hypothesized (theoretical) ML expert to understand boosting, which is generally explained in terms of PAC learning, which draws on computational complexity? that said, i'd also expect a phd in statistics to be able to figure out boosting without taking an undergrad course that worked up from automata. so the halting problem test, while it does capture something, may not be quite right.
