Key points

  • It found that not all data in a replay buffer are equally important: a small subset in conflict regions determines how well forgetting is prevented.
  • It developed a three-stage procedure for selecting memory anchors by locating regions in the policy's latent space where observations overlap but actions conflict.
  • Removing only the top 10% of anchors increased forgetting 4.5-fold on the LIBERO benchmark.
  • ANCHORER, which fills 10% of the buffer with anchors, reduced forgetting on conflicting tasks by 63%.
  • In continual learning over a sequence of two real-robot tasks, it achieved 1.7 times the overall success rate of a random buffer.
