Cache Replacement Models

Parrot

Introduced by Liu et al. in An Imitation Learning Approach for Cache Replacement

Parrot is an imitation learning approach to automatically learn cache access patterns by leveraging Belady’s optimal policy. Belady’s optimal policy is an oracle policy that computes the theoretically optimal cache eviction decision based on knowledge of future cache accesses, which Parrot approximates with a policy that only conditions on the past accesses.
