LLM Evaluation & Benchmarking FAQs

Question 1

How does the 'LLM-as-Judge' pattern work?

Accepted Answer

It provides implementation patterns for using a highly capable model to grade the outputs of other models based on specific rubrics, either individually (pointwise) or by comparing two variants (pairwise).

Question 2

What automated metrics are supported for text generation?

Accepted Answer

The skill supports a wide range of metrics including overlap-based scores (BLEU, ROUGE), semantic similarity (BERTScore, METEOR), and model confidence (Perplexity).

Question 3

Does it include tools for human-in-the-loop evaluation?

Accepted Answer

It provides structured annotation guidelines and frameworks for calculating inter-rater agreement (Cohen's Kappa) to ensure manual evaluations are consistent and reliable.

Question 4

How do I detect if my model performance is getting worse?

Accepted Answer

The skill includes a RegressionDetector that compares new results against a established baseline and flags significant drops in performance beyond a defined threshold.

Question 5

Can this skill help evaluate RAG (Retrieval-Augmented Generation) systems?

Accepted Answer

Yes, it includes specific modules for evaluating retrieval performance using MRR and NDCG, as well as checking for groundedness and hallucination using NLI models.
