the utilization of Toloka service to catch user interactions. Utility code would possibly well per chance even be
came upon right here and you would possibly want to even see how easy it’s to impeach
Metarank installation to salvage steady-time personalization.

Metarank configuration of the demo application is on hand
right here.
You will seemingly be in a position to see how easy it’s to stipulate aspects and can previiew the pre-constructed mannequin primarily based entirely
on the Ranklens dataset.


You will seemingly be in a position to have confidence a look at out our tutorial and play with Metarank in the community!
