does anyone know the answer to this one? since looking it up it kept getting that the feature maps are already in order which doesn’t seem right
A CNN’s lower layers maps edges and contrasts, while its higher layers can get deeper layers, although you probably know this. So if we want to find the correct order, lowest to highest, we can see which one has the most edges then going to the least.
Some factors to consider, other than edges, include: abstractness (how much it resembles the orginial photo), focus on the foreground, noise, and smoothness.
(1) - has a lot of edges, high contrast photo, definitely 0 or 1.
(2) - a few edges, but it’s capture some deeper stuff and is emphasizing the foreground. Maybe 2 or 3.
(3) - Very little edges, rounded and pretty smooth. A few spots near the front are focused on. Has to be near the end.
(4) - Lots of edges (but noticeably less than (1)), smoother than (1), still pretty noisy. Probably right after (1) in the rankings.
(5) - No edges at all, very abstract, smooth, no noise. This is definitely last.
Comparing overall, we know 1 is first, then 4. It gets a little tricky deciding between 2 or 3 next, so we work backwords: 5 is last, then 3 is (it’s smoother, has less noise, and is more abstract than 2), so we know 2 is in the middle.
This results in an answer of \boxed{1, 4, 2 , 3, 5}. These output to \boxed{0,1,2,3,4}
