There shouldnt be.

The group of horses that were elite 278 were roughly half of those that were non-elite.

The only bias in the non-elite group is that I solely used horses that were sold for $200,000 or more from sales that ran at least 5 times and were useless. I figured that was about as good a population of non-elite horses that I could find but because these horses tend to come from a smaller pool of farms it is possible that the program might be picking up something in the background of the image, not the horse itself, as an indicator of non-elite status.

I've got a larger group of close to 10,000 images where only ~350 of these are elite runners which could be more informative/accurate.

Elite Racehorse 78%
Non Elite Racehorse 21%


I hope your predictor is right :)

Could you 2 put up the pics used for our perusal?

Not the best pic to do it off so I probably threw the software a bit lol

This one scored 84% elite , having 4th start tonight at toowoombs long way to go to hit elite but ill keep hoping :)

It certainly does better with the classic conformation shot, head left to right, and all four feet visible and standing posed.

The new model that I am working on has 12 categories (sex-colt,filly; class-elite,nonelite; distance - sprint,miler,long) and I then run the percentages in each variable through a Boosted Decision Tree which reverts back to a binary elite/non-elite answer. I'm hoping with around 10,000 images with outcomes it will be a lot more accurate. It needs to be over 80% to be usable.

97% Elite

What are peoples view of this horses eye ?

Regarding the wall/white eye, it's purely pigmentation going hand in hand with the white facial markings, despite many insisting it denotes a 'mad' temperament

Anyone have opinions on this yearling?

I don't like the angle of the cannon bone from the knee

That's the first thing I look at side on. If it's not straight I won't look any further
