Two layer evaluation

[Prikshit7766]

Description

Robustness testing aims to evaluate the ability of a model to maintain consistent performance when faced with various perturbations or modifications in the input data. For LLMs, this involves understanding how changes in capitalization, punctuation, typos, contractions, and contextual information affect their prediction performance.

Two-layer method where the comparison between the expected_result and actual_result is conducted

• Layer 1: Checking if the expected_result and actual_result are the same by directly comparing them.
  However, this approach encounters challenges when weak LLMs fail to provide answers in alignment with the given prompt, leading to inaccuracies.

• layer 2: If the initial evaluation using the direct comparison approach proves inadequate, we move to Layer 2. we provide three alternative options for evaluation: String distance, Embedding distance, or utilizing LLMs as evaluators.

This dual-layered approach enhances the robustness of our evaluation metric, allowing for adaptability in scenarios where direct comparisons may fall short.
