A new method to boost the speed of online databases

"increase hash function computational time while significantly reducing collisions... significantly speed up searches in huge database... data predictably distribute enables learned models to reduce ratio of colliding keys in dataset from 30% to 15%... With more sub-models learned model produces more accurate approximation, but takes more time.... At certain threshold of sub-models, you get enough information to build approximation that you need for hash function but more won't improve collision reduction"
