Top Ten Easy Animals

Here are the top ten animals that are the easiest to identify in Snapshot Serengeti. Which one takes the prize for easiest? Take the poll. I’ll post the answer next week.

Read on to see how I determine the “easiness” rankings.

The Nitty Gritty

I’ve taken the capture events with a single species of animals in them that were identified by the simple majority-vote algorithm described in the Results from Season 4 post. I left out those capture events that were “hard to figure out.”

Then I looked at all classifications given for capture events for each species and determined the percent correct. So, for example, I’d find all capture events that are of impala. There are 1,371 of them. Then I’d look at all the classifications given for all the impala captures. There are 19,705 of those. Next I would count up how many “impala” classifications there were out of those 19,705 classifications. It turns out there are 13,985. I divide to get 71% correct for impala. I then ranked all the species in terms of their percent correct.

The hardest animals to identify are trickier to rank. Remember that I’ve excluded the “hard to figure out” images, and those are definitely relevant when trying to figure out what’s difficult. But these guys appear to be at the bottom of the “easy” list:

aardwolf, bushbuck, eland, Grants gazelle, impala, kori bustard, reedbuck, rhinoceros, serval, striped hyena, topi, waterbuck
