Hallucination-Free LLMs: Strategies for Monitoring and Mitigation – Wojtek Kuberski, NannyML
The talk will cover why and how to monitor LLMs deployed to production. We will focus on the state-of-the-art solutions for detecting hallucinations, split into two types: 1. Uncertainty Quantification 2. LLM self-evaluation In the Uncertainty Quantification part, we will discuss algorithms to leverage token probabilities to estimate the quality of model responses. This includes simple accuracy estimation and more advanced methods for estimating Semantic Uncertainty or any classification metric. In the LLM self-evaluation part, we will cover using (potentially the same) LLM to quantify the quality of the answer. We will also cover state-of-the-art algorithms such as SelfCheckGPT and LLM-eval. You will build an intuitive understanding of the LLM monitoring methods, their strengths and weaknesses, and learn how to set up an LLM monitoring system easily.
