LooM introduces loop-invariant memory for language models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced LooM (Loop-invariant Memory), a novel approach for causal encoder-decoder language models that enhances their effective depth without proportional memory growth. LooM achieves this by looping only the decoder layers after the first, which access a global memory written once per token. This method allows for flexible compute budgets at deployment time and has demonstrated superior performance on language modeling, zero-shot accuracy, and long-context perplexity compared to single-pass baselines, while maintaining the same cache size.

IMPACT Introduces a method to improve language model efficiency and performance without increasing memory requirements.

    LooM: Loop-Invariant Memory for Causal Encoder-Decoder Language Models

    arXiv:2611.06835v1 Announce Type: new Abstract: Looped Transformers increase effective depth by re-executing shared layers, but three limitations hinder their adoption: memory grows with the loop count, compute can only be adjusted in whole-block steps, and the loop count is hard…
