Key points

  • Existing models struggle to process and remember very long sequences effectively.
  • Transformers have quadratic complexity, which limits the context window.
  • Current approaches lack an effective way to combine different memory types, such as short-term, long-term, and persistent memory.
  • Models face challenges in generalization and length extrapolation.
  • It introduces a neural long-term memory module that learns to remember at test time based on a surprise signal.
  • It presents three architectural variants for integrating memory effectively: Memory as Context, Memory as Gate, and Memory as Layer.
