I managed to traina neural network to properly place markers on a horse at the walk. I trained the network on 50 different horses using different light, horse color, ages, etc and the average error rate was just 9 pixels so it was very accurate in learning where to place the markers.

Here is a video I took of the Breeders Cup winner Accelerate on the left with the markers placed by the algorithm on the right.


And here is one that I downloaded from Twitter of Zoustar and had the algorithm mark up.

Here is the paper that has come out of the work....

Challenging times for the industry, and yet a great opportunity for the practical applications of this research.

Hi Brogers, can you explain this in simple terms please.

GAJ, just in case old mate doesn’t come back, let me help.

The aim of the game here is to create a program that can identify good racehorses using digital inputs - i.e. what’s available via online catalogues. In this case, the video that shows the horse at a walk.

The study is suggesting that pre-training the artificial intelligence will yield better results than simply turning it on & allowing it to train itself from scratch.

Amazing, Thank you, Then would come the gene test I'm guessing.
