Persistent fixed-size memory for machine-learning using recurrent neural networks

Computer-implemented methods and systems provide a persistent fixed-size recurrent memory that supports long or unbounded sequence processing with substantially constant compute and bounded memory. A recurrent model maintains a matrix state updated per chunk from key, value, gate, and optional control signals; a gated error between value and a key-weighted state yields a rank-1 proposal. Chunk proposals are reconciled coordinate-wise by an order-invariant convex combiner; solitary proposals pass unchanged. Queries can be answered from proposals without materializing a full updated state. Multiple asynchronous agents emit sparse updates with overwrite strengths that are merged using sparse convex or max selection and optional optimizer preprocessing. A feedback projection writes higher layer activations into lower layer state to consolidate durable skills and reduce forgetting. The approach enables durable retention, parallel inference-time adaptation, scalable linear-attention approximation, and persistent fixed memory use over arbitrarily long sequences.
