Could Tinder have started using machine learning to select who they show you?

I myself had previously contemplated applying machine learning that would learn from a few hundre of my left and right swipes in order to swipe on my behalf, so this topic is something that had been on my mind already. A couple of days ago Tinder showed me four faces at once and asked me to pick one of them that it would send a super like to on my behalf. Of course that could simply have been four people I’d previously swiped right, rather than being four new people picked on basis of my previous swiping. I also think Tinder has gotten better at showing people I find attractive, but that does not necessarily mean any ML is involved. First of all I have a wider radius set now than I used to so I guess it could be that those people are simply the people that are most popular in general like before but because the area is bigger there are more good looking people.
