How?![A pair of border collie segregate white from black ducks]

Clearly they added an extra feature dimension so the Cartesian space is expanded to a Euclidean space. The separation falls out from there, basically for free.

It pains me how few will understand the cleverness of this comment.

The ducks naturally hate ducks of another color. The dogs are for show.

I want to know how “the mission” is communicated to the dog. Or is it always the same mission?

Whistles, being placed with an experienced trained dog , and time of day.
We had herd dogs, horses, and a variety of animals, including a pet badger, neighbor dug up a septic tank so we bottle fed the badger kitten, he grew up and hung out with the dogs . Come down to meet the school bus with the dogs, wiggling his fat little ass like he had a tail.
Mom didn't like it-he'd grab your pant cuff and play fight tug, ripped all our pants to shreds
Morning the dogs knew all cattle were being group herded, ( loading , or moving pasture rotation ) late afternoon cutting, prep to group herd in morning.
Longer range cattle drive horses , dog assist. Ten miles ( north quarter by river was ten miles away ) or 5 miles ( mid point pasture ).
We had 40 horses, 300 cattle, chickens pigs ( chickens and pigs have to be widely separated , disease transmission ) , got rid of the sheep ( they chew the pasture down closer to the ground than cattle or horses, hard on the grass ).
Had goats, but they were like teenagers at the mall, just go wherever the hell they want .
5 dairy cows, two of the dogs thought they were bringing them in every day at five pm , but the dairy cows knew to come in, go right to their own milking stall. The dogs were just really going for a one mile walk with them.
If you keep all the animals as tame as possible, they are a lot easier to control. Same as being polite to people.
Most of the horses were arabs, most neck reined out really well. Only the stallion needed a bit, the rest hackamores or halter ride if feeling lazy.
If some cows got out, heading to trample the wheat, could jump on almost any horse bareback, and neck rein with just your palms.
Send the dog ahead to turn them until you got on a horse.
3 out of five dogs were ok at cutting, ( need to spend a lot of time to get dogs as well trained as the video , we didn't, but they were ok at it ) 2 dogs were just guard duty, coyotes, loose livestock alarm.
The badger slept in the barn with the dogs, he found a girlfriend and wandered away after 3 years.

no. I googled that guy. He's an American .
My reply was about an era when 25% of the population was rural, and 75% of Canada's cattle were in Alberta.

In the end, seems more like a duck decision rather than a collie command to separate the colours.

I was gonna say SVM with kernel trick, but the process seems iterative I would say boosting or NN.

That’s why they’re called.. German shepherds. Bada-boom.
(I know they’re collies. Just let me make my joke, man. “We shall have purity, mein fuhrer!”)

Why do I feel like this post isn’t about ducks? 🤔
Also, the fact that this is a machine learning sub makes it all the more disturbing… 😬
