Researchers have developed RIFAR, a novel approach for continual robot learning that addresses the challenge of retaining skills without excessive data storage. RIFAR combines reliability screening with drift-aware replay selection to reconstruct and select relevant past experiences. This method reconstructs trajectories from demonstration prefixes and uses an inverse-dynamics model to ensure action-visual consistency. By comparing action predictions before and after adaptation, RIFAR reselects trajectories that exhibit significant drift, leading to improved performance on benchmarks like LIBERO-Goal while retaining a minimal number of historical steps.
