Comba: Improving Bilinear RNNs with Closed-loop Control

arXiv — cs.LGThursday, December 4, 2025 at 5:00:00 AM
  • The introduction of Comba, a novel variant of Bilinear RNNs, leverages closed-loop control theory to enhance recurrent memory management, presenting a scalar-plus-low-rank state transition model. This development builds on recent advancements in sequence modeling, including Gated DeltaNet and RWKV-7, which have improved performance through innovative memory supervision techniques.
  • Comba's design aims to address the limitations of existing state-space models and gated linear attentions, potentially offering superior performance in sequence modeling tasks. The implementation of a hardware-efficient chunk-wise parallel kernel in Triton further emphasizes its practical application in large-scale training scenarios.
  • This advancement reflects a broader trend in artificial intelligence towards integrating control theory with machine learning models, as seen in related innovations like Gated KalmaNet and DiffuApriel. These developments highlight ongoing efforts to enhance memory retention and inference efficiency in AI systems, addressing critical challenges in the field.
