Log10 has developed a novel approach to improve evaluation accuracy for large language models (LLMs) through latent space techniques, which enhance hallucination detection and numeric scoring. Their method, termed latent space readout (LSR), allows for rapid customization and is significantly more sample efficient than traditional fine-tuning, requiring only a small number of human feedback examples. This approach can adapt to various base models without the need for extensive retraining, making it suitable for domain-specific applications. The research highlights the importance of structured evaluations in AI applications, as relying solely on subjective assessments can lead to financial and reputational risks. LSR has shown promising results in benchmarks for hallucination detection, achieving accuracy comparable to fine-tuned models while maintaining flexibility in adjusting recall and precision based on application needs. Additionally, LSR can be utilized for numeric scoring of custom evaluation criteria, demonstrating its versatility in enhancing the evaluation process for LLMs. The findings suggest that LSR can effectively bridge the gap between model performance and practical application, providing a more efficient and reliable evaluation framework for AI developers.

5 commentsI wish there was a global mandatory course before these substacky authors write for fame.
I thought maybe you offer hallucination detection, but I also don't see that. RAG evals also not visible
