If you study a CPU you will find various cache levels (L1, L2, …) In fact, the further away from the CPU the colder the memory is considered. Having the memory the instructions need in CPU cache allows for faster response. Having to load data from remote memory locations or secondary cache lines is considered COLD (takes longer.).

Their result is particularly promising for specialized index structures termed as learned indexes which has potential to replace B-Trees without major re-engineering. They demonstrated that neural nets based learned index outperforms cache-optimized B-Tree index by up to 70% in speed while saving an order-of-magnitude in memory.
