Research Paper Overview
Meta-Learning for Cold-Start Personalization in Prompt-Tuned LLMs
Summary
This paper presents a meta-learning framework for parameter-efficient prompt-tuning to personalize large language model-based recommender systems in cold-start scenarios. By treating each user as a task, the model learns soft prompt embeddings optimized via first- and second-order meta-learning methods, enabling fast adaptation with minimal user history. The approach outperforms strong baselines on multiple datasets and supports real-time personalization and risk profiling in financial systems, enhancing detection latency and network stability.
