Improving generalization for temporal difference learning: The successor representation. Appropriate generalization between states is determined by how similar their successors are, and representations should follow suit. Successor-style representations have many advantages for reinforcement learning: for example, they can help an agent generalize from past experience to new goals, and they have been proposed as explanations of behavioral and neural data from human and animal learners.They also form a natural bridge between model-based and model-free RL methods: Improving generalization for temporal difference learning: The successor representation.

SRSA quantifies regularities in scan patterns using temporal-difference learning to construct a fixed-size matrix called a successor representation (SR, ). a variant of temporal difference learning that uses this richer form of eligibility traces, an algorithm we call Predecessor Representation. Successor representation methods would adapt to the reward revaluation ($r(s)$ will quickly fit the new reward distribution for the states $5$ and $6$), but not to the transition revaluation: $6$ is never a successor state of $1$ in the re-learning phase, so the SR matrix will not be updated for the states $1$ and $2$.
