DiaLong: Benchmarking Reminiscence in Long-Context Dialogues

How well can transformer-based Large Language Models (LLMs) retain and recall memories in long contexts of dialogue?

Key points

  • We present DiaLong, a long-context dialogue dataset and accompanying memory task that standardizes evaluation in this space.
  • Our selected memory task is fact recall: classify 40 candidate facts about a dialogue as true or false.
  • In testing both the latest LLMs and proposed memory enhancements on DiaLong, we demonstrate that more work needs to be done to enable LLMs with better memory performance.
  • By enhancing memory capabilities, LLMs can improve in maintaining coherence, relevance, and human-like interaction over extended conversation.
