Phasor Memory Networks tackle gradient instability in explicit memory models

Researchers have introduced Phasor Memory Networks (PMNet), a novel architecture designed to overcome the gradient instability issues that have historically plagued explicit memory models. By employing Unitary Phasor Dynamics and Hierarchical Learnable Anchors, PMNet maintains stable gradients, enabling more effective training through Backpropagation Through Time. In a byte-level demonstration, PMNet successfully utilized an 85-slot memory tree to achieve near-perfect retrieval over long temporal distances, outperforming larger Mamba models in zero-shot long-context robustness.
