How can learned sort be adapted to make it cache-efficient? For this, the authors use the Recursive Model Index (RMI) architecture as first introduced in ‘ The case for learned index structures ‘ In brief, RMI uses layers of simple linear models arranged in a hierarchy a bit like a mixture of experts.
