Struct CoverageFactor 

Source 
pub struct CoverageFactor;
Expand description

CoverageFactor — favours categories the user has interacted with less.

Prevents the engine from over-drilling one category. Items in under-represented categories score higher.

Domain mapping: learning → topic spread (algebra, geometry, …) ecommerce → category spread (electronics, clothing, …) travel → region spread (Asia, Europe, …) content → genre spread (thriller, romance, …)
