Here is a high stage overview of Metarank integration:

  • outline your aspects with straightforward YAML configuration file
  • send historical occasions and metadata thru a JSON API
  • fade Metarank to practice the mannequin
  • send steady-time occasions to a working event of Metarank
  • exhaust pre-trained mannequin to personalize your listings in steady-time

High-stage Metarank aspects overview

  • Built-in characteristic store to compute aspects veteran for on-line and offline coaching
  • YAML configuration to stipulate the constructing of your files and aspects that can well comprise:

    • relative aspects (e.g. percentage of clicks per merchandise over the entire series of clicks)
    • user-explicit aspects (e.g. user agent parser, geoip)
  • REST API or Kafka connector to receive occasions and metadata updates
  • Offline and on-line (steady-time personalization) operation modes
  • Level to mode to label how closing ranking is computed
  • Local mode to maneuver Metarank in the community without deploying to a cluster
  • Cloud native: deploy Metarank to Kubernetes or AWS

Who needs to be the utilization of Metarank?

Metarank is exchange-agnostic and would possibly well per chance even be veteran in any location of your application where some announce is displayed.
Metarank will suit teams that are most attention-grabbing initiating to introduce Machine Discovering out and folks that already have confidence discovery teams that work on personalization and proposals.

The Demo utilizes Ranklens dataset that we have confidence got constructed
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!

In-depth Doctors

Metarank is an Alpha: it be early days of pattern. It’s nicely-coated with tests and runs in manufacturing several systems serving steady web announce online traffic, even though we don’t imply but to maneuver it without developer enhance.
