Researchers have developed a novel approach using a "surprise" signal, derived from prediction errors in a frozen encoder's latent space, to enhance both plasticity and metacognition in AI systems. One application demonstrated improved retention of ImageNet classes by consolidating recent traces into a slow linear readout, recovering significant points of retention for DINOv2 and I-JEPA backbones. A second system utilized this surprise signal to modulate a vision-language model's behavior, allowing it to respond assertively to known concepts, hedge on partially familiar ones, and learn novel concepts from single user utterances, significantly outperforming the model's own confidence metrics.
