Ensemble Methods
7 frameworks — Combine multiple reasoning paths, prompts, or outputs to achieve more reliable and accurate results.
Overview
Ensemble methods combine multiple reasoning paths, prompts, or outputs to achieve more reliable and accurate results. By generating diverse solutions and selecting the best, these techniques reduce the impact of any single error or bias.
Use ensemble methods when reliability is critical — when a wrong answer is worse than a slower process. They are ideal for automated pipelines, evaluation tasks, and any scenario where you can trade computation time for accuracy.
