Re: Evaluator for complimentary purchase

[Alexey Grachev]

Hi Donald,

thanks.
I first need the tutorial to build a rec system based on complimentary 
purchase engine.

Does someone have experience with that? What stack did you use?


Greetings,


Alexey

Hi Alexey,

I believe you will need to build the evaluator. There is a guide at
