RARE (Retrieval-Augmented Reasoning Modeling): A Scalable AI Framework for Domain-Specific Reasoning in Lightweight Language Models

The RARE (Retrieval-Augmented Reasoning Modeling) framework aims to enhance domain-specific reasoning in lightweight language models by separating knowledge storage from reasoning development. Drawing on Bloom’s Taxonomy, it prioritizes contextual rationale over memory-heavy learning and uses external databases for domain knowledge. Experiments indicate that RARE-trained models outperform larger models like GPT-4 in healthcare-focused tasks, achieving over 20% higher accuracy on some benchmarks. This scalable approach suggests that focusing on reasoning skills and using structured, contextual learning can be more effective than simply increasing model size.
