41. DONNA : Ah, yes, he spoke of knowledge in terms of being either " a priori " or " a posteriori ." 42. This type of error analysis is usually called " a posteriori " since we compute the error after having computed the approximation. 43. These a posteriori physicalists endorse some version of what Daniel Stoljar ( 2005 ) has called " the phenomenal concept strategy ". 44. He called those concepts that result from abstraction " a posteriori concepts " ( meaning concepts that arise out of experience ). 45. The method of maximum a posteriori estimation then estimates \ theta as the mode of the posterior distribution of this random variable: 46. Another problem with the " a posteriori " moral search is that we lack an epistemic account of how we access moral facts. 47. In a posteriori methods, a representative set of Pareto optimal solutions is first found and then the DM must choose one of them. 48. A popular choice for ? is to provide " maximum a posteriori " ( MAP ) estimates of it with some chosen prior. 49. The scientific method employs " a posteriori " reasoning and the use of Bayesian inference to measure the validity of a given theory. 50. This is verified a posteriori in the hybrids spectra are yet a questioned matter in view of the experimental observation of such exotic states.
