Pervformer | Fixed

A robot navigating a warehouse doesn't need to remember every pixel from 10 seconds ago. It needs to remember that a forklift moved a pallet (semantic) and that the path is now clear (spatial). PervFormer's memory probes act as a working memory, drastically reducing drift in SLAM-based systems.

Note on the topic: Since "PervFormer" is not a widely published standard model (as of my last training data), this blog post invents a plausible, state-of-the-art architecture based on current trends in efficient attention (FlashAttention, Mamba, RetNet) and video transformers.
