LPC-SM: Local Predictive Coding and Sparse Memory for Long-Context Language Modeling

📰 ArXiv cs.AI

LPC-SM is a hybrid autoregressive architecture for long-context language modeling that separates local attention and persistent memory

advanced Published 7 Apr 2026
Action Steps
  1. Separate local attention and persistent memory using Orthogonal Novelty Transport (ONT)
  2. Implement predictive correction and run-time control within the same block
  3. Use LPC-SM to handle long-range state and local interaction in sequence modeling
  4. Evaluate the performance of LPC-SM against traditional attention-based models
Who Needs to Know This

NLP engineers and researchers on a team can benefit from LPC-SM as it provides an alternative approach to traditional attention-based models, allowing for more efficient and effective long-context language modeling

Key Insight

💡 LPC-SM provides an alternative decomposition of sequence modeling that can be more efficient and effective than traditional attention-based models

Title: LPC-SM: Local Predictive Coding and Sparse Memory for Long-Context Language Modeling

Abstract:
arXiv:2604.03263v1 Announce Type: cross Abstract: Most current long-context language models still rely on attention to handle both local interaction and long-range state, which leaves relatively little room to test alternative decompositions of sequence modeling. We propose LPC-SM, a hybrid autoregressive architecture that separates local attention, persistent memory, predictive correction, and run-time control within the same block, and we use Orthogonal Novelty Transport (ONT) to govern slow-m
