用大模型知识蒸馏出高效对话过滤器,只让重要片段进大模型。

Efficient Intent-Based Filtering for Multi-Party Conversations Using Knowledge Distillation from LLMs

  • 从大模型蒸馏知识,训练轻量移动BERT做多意图分类。
  • 仅传递相关对话片段,实验显示运行成本显著降低。
  • 适合资源受限场景下的多角色对话智能处理。

大型语言模型(LLMs)在对话AI中表现出色,可实现开放式回复、摘要生成、意图分类与洞察提取等任务。然而其资源消耗大,需大量内存与计算能力。为此,我们提出一种低成本方案:不处理所有对话片段,而是根据下游应用需求,筛选出感兴趣的片段再交由大模型处理。本文提出一种基于大模型知识蒸馏的意图驱动过滤方法,专为计算资源受限环境优化。通过融合多种策略构建多样化的多角色对话数据集,并标注目标意图,用于微调MobileBERT模型进行多标签意图分类。该模型在效率与性能间取得平衡,能有效依据意图筛选对话片段。实验表明,仅将相关片段送入大模型处理,可显著降低整体运行成本,具体降幅取决于意图类型与数据分布。

原文摘要 · Abstract (English)

Large language models (LLMs) have showcased remarkable capabilities in conversational AI, enabling open-domain responses in chat-bots, as well as advanced processing of conversations like summarization, intent classification, and insights generation. However, these models are resource-intensive, demanding substantial memory and computational power. To address this, we propose a cost-effective solution that filters conversational snippets of interest for LLM processing, tailored to the target downstream application, rather than processing every snippet. In this work, we introduce an innovative approach that leverages knowledge distillation from LLMs to develop an intent-based filter for multi-party conversations, optimized for compute power constrained environments. Our method combines different strategies to create a diverse multi-party conversational dataset, that is annotated with the target intents and is then used to fine-tune the MobileBERT model for multi-label intent classification. This model achieves a balance between efficiency and performance, effectively filtering conversation snippets based on their intents. By passing only the relevant snippets to the LLM for further processing, our approach significantly reduces overall operational costs depending on the intents and the data distribution as demonstrated in our experiments.
