Table 1 - Example of some LLM tasks with common benchmark datasets and their respective metrics. Please note for many of these tasks, there are multiple benchmark datasets, some of which have not been mentioned here.

Metric Selection

Metric

Usage

Accuracy

Measures the proportion of correct predictions made by the model compared to the total number of predictions.

Precision

Measures the proportion of true positives out of all positive predictions.

Recall

Measures the proportion of true positives out of all actual positive instances.

F1 Score

Measures the harmonic mean of precision and recall.

Perplexity

Measures the model's uncertainty in predicting the next token (common in text generation tasks).

BLEU

Measures the similarity between machine-generated text and reference text.

ROUGE

Measures the similarity between machine-generated and human-generated text.

METEOR

May have higher computational complexity compared to BLEU or ROUGE.Requires linguistic resources for matching, which may not be available for all languages.

Pros

Cons

Simple interpretability. Provides an overall measure of model performance.

Sensitive to dataset imbalances, which can make it not informative. Does not take into account false positives and false negatives.

Useful when the cost of false positives is high. Measures the accuracy of positive predictions.

Does not take into account false negatives.Depends on other metrics to be informative (cannot be used alone).Sensitive to dataset imbalances.

Useful when the cost of false negatives is high.

Does not take into account false negatives.Depends on other metrics to be informative (cannot be used alone)and Sensitive to dataset imbalances.

Robust to imbalanced datasets.

Assumes equal importance of precision and recall.May not be suitable for multi-class classification problems with different class distributions.

Interpretable as it provides a single value for model performance.

May not directly correlate with human judgment.

Correlates well with human judgment.Easily interpretable for measuring translation quality.

Does not directly explain the performance on certain tasks (but correlates with human judgment).Lacks sensitivity to word order and semantic meaning.

Has multiple variants to capture different aspects of similarity.

May not capture semantic similarity beyond n-grams or LCS.Limited to measuring surface-level overlap.

Addresses some limitations of BLEU, such as recall and synonyms.

May have higher computational complexity compared to BLEU or ROUGE.Requires linguistic resources for matching, which may not be available for all languages.

Table 2 - Common LLM metrics, their usage as a measurement tool, and their pros and cons. Note that for some of these metrics there exist different versions. For example, some of the versions of ROUGE include ROUGE-N, ROUGE-L, and ROUGE-W. For context, ROUGE-N measures the overlap of sequences of n-length-words between the text reference and the model-generated text. ROUGE-L measures the overlap between the longest common subsequence of tokens in the reference text and generated text, regardless of order. ROUGE-W on the other hand, assigns weights (relative importances) to longer common sub-sequences of common tokens (similar to ROUGE-L but with added weights). A combination of the most relevant variants of a metric, like ROUGE is selected for comprehensive evaluation.
