Catastrophic forgetting, rehearsal and pseudorehearsal

ROBINS, ANTHONY·1995·Connection Science

Abstract

This paper reviews the problem of catastrophic forgetting (the loss or disruption of previously learned information when new information is learned) in neural networks, and explores rehearsal mechanisms (the retraining of some of the previously learned information as the new information is added) as a potential solution. We replicate some of the experiments described by Ratcliff (1990), including those relating to a simple 'recency' based rehearsal regime. We then develop further rehearsal regimes which are more effective than recency rehearsal. In particular, 'sweep rehearsal' is very successful at minimizing catastrophic forgetting. One possible limitation of rehearsal in general, however, is that previously learned information may not be available for retraining. We describe a solution to this problem, 'pseudorehearsal', a method which provides the advantages of rehearsal without actually requiring any access to the previously learned information (the original training population) itself. We then suggest an interpretation of these rehearsal mechanisms in the context of a function approximation based account of neural network learning. Both rehearsal and pseudorehearsal may have practical applications, allowing new information to be integrated into an existing network with minimum disruption of old information.

  • Replay strategies in continual learning and human/neural replay phenomena inspired the authors' exploration of whether simple continual learning strategies remain effective for LLMs.

    “Inspired by replay strategies in continual learning (Robins, 1995; Rolnick et al., 2019; De Lange et al., 2021) as well as by the replay phenomena observed in humans (Smolen et al., 2016) and in neural network models (Amiri et al., 2017), we explore whether simple continual learning strategies remain effective for LLMs.”

  • Replaying data from pre-training or previous training stages can alleviate forgetting, but is data-inefficient and not scalable as experience grows.

    “While replaying data from pre-training or previous training stages can alleviate forgetting (Lin, 1992; Robins, 1995; Chen et al., 2025), this strategy is data-inefficient and not scalable as we grow the amount of experience.”

    From Continual Learning via Sparse Memory Finetuning (2025) · cites this paper as Robins, 1995

  • Before deep learning, Robins stated that catastrophic forgetting could be mitigated through rehearsal or pseudo-rehearsal.

    “Before the era of deep learning, Robins [86,87] stated that catastrophic forgetting could be mitigated through rehearsal or pseudo-rehearsal.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
