Add Typo

This test checks if the NLP model can handle input text with typos. A typo frequency dictionary is used to apply most common typos to the input data.

alias_name: add_typo

To test QA models, we are using QAEval from Langchain where we need to use the model itself or other ML model for evaluation, which can make mistakes.

Config

add_typo:
    min_pass_rate: 0.7
    prob: 0.5 # Defaults to 1.0, which means all words will be transformed.
    parameters:
      count: 1 # Defaults to 1

You can adjust the level of transformation in the sentence by using the “prob” parameter, which controls the proportion of words to be changed during add_typo test.

• min_pass_rate (float): Minimum pass rate to pass the test.
• prob (float): Controls the proportion of words to be changed.
• count (int): Number of variations of sentence to be constructed.
