What is prioritised experience replay?
Prioritised experience replay: A refinement of replay in which transitions with larger TD error are sampled more often, since they have the most to teach. Importance weights correct the bias this sampling introduces.
Prioritised experience replay: an example
A rare transition with error 5.0 is replayed far more often than one with error 0.01.
