this methodology is worthless in practice when the total number of examples is small in relation to the natural variation that exists among different observations ... it therefore needs to be immediately replaces by Bayesian methods, for example, which can deliver reliable measures of the uncertainty that exists This looks like dogmatic madness, but maybe the article just makes them sound bad. Can anyone comment on how reliable the uncertainty coming out of a Bayesian algorithms is?
