Tutorials on recommendation engines

Gems / Libraries • Asked by TL

Hi Chris,

I searched for videos on recommendation itens but couldn't find any.

We run a real estate website and would love to provide similarities recommendations (like "users that viewed this property also liked ...". There seems to be a handful of gems to acomplish this, but it's not trivial and it would be great to have a tutorial with your expertise. Any plans for a video like this?


Hey TL,

That's definitely a great suggestion and you're right, those recommendations engines aren't trivial.

I'd probably check out this gem first: https://github.com/davidcelis/recommendable

And if that didn't work out, I'd try building my own implementation. It seems most of these gems aren't too well maintained.

Thanks a lot guys!
