The Dynamical Memory Transformer (DMT) is a hybrid architecture that decouples sequence encoding from information retrieval. It employs multiple memory units—each a dynamical system with a complex diagonal recurrent matrix—updated via an input‑dependent leak rate, while the decoder uses attention to read these units without accessing the full token history. This design enables an associative scan with linear total work and logarithmic parallel depth, keeping recurrent states and cache sizes constant during autoregressive inference. DMT outperforms Transformers on several cognitive tasks and matches their language‑modeling performance, though it lags behind Mamba in language modeling; it also shows superior length extrapolation on selective copy tasks.

The paper introduces Gated Recurrent Transformers, a depth‑sharing architecture that brackets a single shared core with fixed prelude and coda blocks and uses a lightweight projection and element‑wise update gate to modulate recurrent updates. This design allows functional specialization across recurrences while reducing memory footprint. Experiments show that, under equal FLOPs or parameter budgets, the recurrent model matches or surpasses deeper GPT‑2 Small baselines, achieving similar or better accuracy with fewer parameters and lower peak decoding memory.

Abstract: In contrast to RNNs, which compress their history into a single hidden state, Transformers can attend to all past tokens directly. However, standar...
