I've always been amazed at how at the epicenter of a large city or event there are many normal looking things that contribute subtly or inadvertently to the overall awe. It's not like everything in Times Square is magical, yet the sum of them is.

I wonder how many of these more ordinary objects or store fronts you could remove and still keep the aesthetic wonder of the place. Take out the garbage cans, the street lights, the cross walks, bring the buildings a little closer together or father apart. At what point does it's quality simply change?

There is a way to test the validity of their result. Go to figure 6 of the paper, in which they have a set of "Extracted Visual Elements" for each city. Cover the captions under each set, then see if you can pick the city. If their results are valid, shouldn't the essence of the city be in their selected photos, allowing a person to identify the city by looking at them?

I picked London, but none of the others (which might just reflect my lack of knowledge of each city). What do others see in figure 6?

There's no reason for a human to be as good as the machine, even though it seems like a very human task. Maybe you can use the results as input to get better at that task yourself?

Great idea. I got 3 cities in Europe an one in the US right. I thought Prague was Berlin though, and didn’t get Boston

Anecdotally, after having lived in Paris for ~6 months, one of the most noticeable aspects of the city is its relative uniformity. Unlike Berlin, London, or Prague, you can wander for awhile in Paris and essentially see the same style of architecture and urban landscape repeated. It has something of an “endless” effect on your time perception.
