How many cats on Habré?

Recently, I was traveling by bus from Toronto to New York, it was dark outside, there was a bit of port inside, I didn’t want to sleep at all, and I decided to sort out Deep Learning. I downloaded Caffe , fed him a couple of pictures, on which the ball and banana were correctly recognized. I wanted to recognize something more interesting, and I remembered that somewhere on the hard drive I had a dump of a habrahabr, which I did when I was in the course of information retrieval in the ShAD Yandex.

It took several minutes to write a script that recognizes what is depicted on the avatar of a habial user and felines all cats, and it took several days to update the dump to the current one and the recognition of images, and now I can say that there are at least 748 cats in it.

Under Habrokat you can read a little more details and look at all the cats.

Within a few days, my spider received a habrahabr, and when I saw that I had over 500,000 pages of habra users downloaded, I stopped it. As a result, I had information about 527468 users. Of these, 73193 were avatars.

Next, with the help of Caffe, I received for each picture the first five most likely tags. After filtering by cat tags, 1013 avatars remained. Among them were some numbers of non-cats, for example, owls are often recognized as cats.

Alf, no matter how funny, half primate, and half a cat. Classes are defined as: 'primate', 'monkey', 'lion', 'Old World monkey', 'feline'.

But Zelenyikot is not a cat, the closest that is recognized is the 'giant panda'.

After I manually removed erroneously credited cats, 748 avatars remained. All of them are shown in the picture below.

UPD In the comments indicated that the three avatars are not cats. So the method finds 745 cats.
