Researchers have introduced the Dynamical Memory Transformer (DMT), a novel hybrid architecture designed to improve how models handle long sequences. Unlike standard transformers that store an explicit history, leading to increased computational cost with longer contexts, or State Space Models that compress the past into a fixed state, DMT separates sequence encoding from information retrieval. It employs multiple memory units, each managed by a dynamical system with an input-dependent leak rate, allowing attention mechanisms to read and combine information without processing the entire token history. This approach aims for constant cost attention and fixed-size recurrent states during inference, showing promise in cognitive tasks and language modeling, though it currently lags behind Mamba in pure language modeling performance.
