Papers with multi-turn dialogue tasks
MIDAS: Multi-level Intent, Domain, And Slot Knowledge Distillation for Multi-turn NLU (2025.findings-naacl)
Copied to clipboard
| Challenge: | Existing Large Language Models (LLMs) can generate coherent text, but they struggle to recognise user intent behind queries. |
| Approach: | They propose a novel approach leveraging multi-level intent, domain, and slot knowledge distillation for multi-turn NLU. |
| Outcome: | The proposed model improves multi-turn conversation understanding by integrating teacher teachers into a student model. |
DP3: Differentially Private Prompt Perturbation for Multi-turn LLM Inference (2026.findings-acl)
Copied to clipboard
| Challenge: | Large language models (LLMs) are widely used for text understanding and generation . existing methods that assume single-turn interactions break down in multi-turn settings . |
| Approach: | They propose a differentially private prompt perturbation framework for multi-turn LLM inference . DP3 constructs a perturbation mapping table to reuse perturbations for recurring tokens . |
| Outcome: | The proposed framework reduces privacy costs and degrades cross-turn semantic coherence . it also provides a context-aware utility function to maintain semantic consistency across turns . |
Sparse Rewards Can Self-Train Dialogue Agents (2025.findings-acl)
Copied to clipboard
| Challenge: | Recent advances in large language models have been driven by supervised fine-tuning and high-quality human feedback. however, acquiring meaningful human feedback has become increasingly challenging and costly. |
| Approach: | They propose a method that empowers LLM agents to enhance their performance without external feedback. |
| Outcome: | The proposed method improves tool-based interactions while preserving general model capabilities across diverse benchmarks. |
