New SeDeM framework enhances long-context QA in LLMs

Researchers have introduced SeDeM, a novel framework designed to improve the efficiency of long-context question answering in large language models. SeDeM decouples the storage of compressed information from the decoder's conditioning process. It achieves this by extracting hidden states from intermediate Transformer layers, storing them as memory blocks, and then selectively decompressing only the relevant blocks for the decoder. This approach reduces computational costs and improves throughput compared to existing compression methods and full-context processing, while also enhancing question-answering accuracy on several benchmarks. AI

IMPACT This framework could lead to more efficient and accurate long-context processing in LLMs, benefiting applications requiring extensive document analysis.

    SeDeM: Selective Decompression of Hidden-State Memories for Long-Context Question Answering

    arXiv:2608.00311v1 Announce Type: new Abstract: Long-context inference with large language models (LLMs) is costly: self-attention during prefill scales quadratically with sequence length, and the key-value (KV) cache grows with the number of processed tokens. Larger context wind…
