Lngram: N-gram Conditional Memory in Latent Space

arXiv:2605.24869v1 Announce Type: new Abstract: Sequence modeling requires both compositional reasoning and local static knowledge retrieval, yet standard Transformers handle both through dense computation. Engram partially decouples retrieval from the backbone, but its token-based keys remain tied to text tokenization and hash compression. We propose Lngram, a latent-space conditional memory module that learns discrete symbols directly from hidden states and performs N-gram lookup over these symbols. This design removes the dependence on tokenizer IDs and naturally extends to non-text modalit

Why this matters
Why now

The continuous drive for more efficient and robust sequence modeling in AI, particularly given the limitations of current Transformer architectures in handling both compositional reasoning and local knowledge retrieval, necessitates new approaches.

Why it’s important

This development proposes a novel memory module that enhances AI models' ability to learn and retrieve information more efficiently, potentially improving performance across diverse modalities beyond text.

What changes

AI models could become more robust and less dependent on specific tokenization schemes, broadening their applicability and improving their ability to handle non-textual data directly.
