Jan 15, 2019 at 18:40 comment added Sycorax @nbro Sure, you could think of it that way. This is another reason why I prefer the "input" and "output" language: it's very general. The fact that these distinctions are really differences in perspective is important to keep in mind. Another person might not think of an image as a matrix of features, but instead think of it as a raw input, which must be transformed by feature extraction. Unlike mathematical definitions and concepts, there doesn't seem to be an enormous downside to being flexible in terminology.
Jan 15, 2019 at 18:31 comment added Sycorax @Tim I don't see "random variable" appear in any sentence with a question mark, so my reading was that "random variable" was introduced as a characterization of the wikipedia articles. I suppose that OP may have a question about random variables, but s/he has yet to ask it.
