Troche mnie dezorientuje rozróżnienie tych terminów w języku angielskim.
The quantity p(D|w) on the right-hand side of Bayes’ theorem is evaluated for
the observed data set D and can be viewed as a function of the parameter vector
w, in which case it is called the likelihood function. It expresses how probable the
observed data set is for different settings of the parameter vector w. Note that the
likelihood is not a probability distribution over w, and its integral with respect to w
does not (necessarily) equal one.
