Understanding the builds effectively used by players in RPG looter online games is key for designers and other stakeholders; but due to combinatorial explosion inherent to the nature of data, traditional unsupervised machine learning approaches often fail at extracting meaningful and actionable results.

We propose a novel and original method - called "BaT" - to automatically segment high volumes of player in-game data into meaningful player builds, that produce easily interpretable builds clusters in a fast, efficient, and scalable way.


Applying unsupervised machine learning to segment in-game player data into meaningful player builds and understand where is the new meta, is not an easy challenge.
Attendees learn about a novel & original approach that is able to perform this task and produce understandable & actionable results for non-ML literate audience.

Intended Audience

Game designers, game analysts, data scientists, game developers, as well as general management.

The presentation focuses on the problematic and provides high-level highlights on the core method, as well as concrete examples from a live game-as-a-service.
