LLM Performance Evaluation FAQs

Question 1

What metrics does this skill support for text generation?

Accepted Answer

It supports a wide range of metrics including BLEU for translation, ROUGE for summarization, BERTScore for semantic similarity, and custom groundedness checks for RAG applications.

Question 2

Can I use this for statistical A/B testing?

Accepted Answer

Yes, the skill includes a statistical testing framework that performs T-tests and calculates effect sizes (Cohen's d) to determine if model improvements are statistically significant.

Question 3

How does it handle regression testing?

Accepted Answer

It features a RegressionDetector that compares new model results against a baseline and flags any metric decreases that exceed a defined significance threshold.

Question 4

Does it provide support for human-in-the-loop evaluation?

Accepted Answer

Yes, it provides standardized annotation task structures and utilities to calculate inter-rater agreement using Cohen's Kappa score to ensure evaluation consistency.

Question 5

How does the LLM-as-judge pattern work?

Accepted Answer

This pattern uses a highly capable model to evaluate the outputs of other models based on specific criteria like accuracy, helpfulness, and clarity, providing a scalable alternative to human review.
