Mastering LLM Techniques: Evaluation

Originally published at: https://developer.nvidia.com/blog/mastering-llm-techniques-evaluation/

Evaluating large language models (LLMs) and retrieval-augmented generation (RAG) systems is a complex and nuanced process, reflecting the sophisticated and multifaceted nature of these systems. Unlike traditional machine learning (ML) models, LLMs generate a wide range of diverse and often unpredictable outputs, making standard evaluation metrics insufficient.  Key challenges include the absence of definitive ground…
