Scalable and Cost Effective High-Cardinality Classification with LLMs via Multi-View Label Representations and Retrieval Augmentation (2025.emnlp-industry)
Copied to clipboard
| Challenge: | Existing methods for labeling contact center interactions show significant inconsistencies and sensitivity to label ordering. |
| Approach: | They propose a two-step retrieval-augmented classification framework enhanced with a multi-view representation of labels. |
| Outcome: | The proposed method significantly improves accuracy and consistency over baseline methods. |
Beyond Instruction Optimization: Multi-Agent Error-Driven Class Description Refinement for LLM-Based Classification (2026.acl-industry)
Copied to clipboard
| Challenge: | Large Language Models have demonstrated considerable efficacy in classification tasks . however, their performance depends on two critical prompt components: Task Instructions (HOW to classify) and Class Descriptions (WHAT defines each class). |
| Approach: | They propose a multi-agent framework for iteratively refining class descriptions based on classification errors. |
| Outcome: | Empirical evaluation shows up to 20.71% accuracy improvements over static class descriptions. |
