New AI framework TeLAPA preserves multiple diverse policies to overcome plasticity loss in continual reinforcement learning tasks

TeLAPA (Transfer-Enabled Latent-Aligned Policy Archives) maintains behavioral diversity by organizing multiple policies into per-task archives rather than relying on a single evolving policy

The framework addresses 'loss of plasticity' - where previously successful policies fail to provide good starting points for rapid adaptation after task interference

Inspired by quality-diversity methods, TeLAPA uses a shared latent space to keep archived policies comparable and reusable even as environments shift over time

Shifts continual RL approach from retaining isolated solutions to maintaining skill-aligned policy neighborhoods with competent behavioral alternatives
