EvaluationDatasetMetricConfig

Structure Class

EvaluationDatasetMetricConfig dataclass

Defines the prompt datasets, built-in metric names and custom metric names, and the task type.

Attributes

dataset instance-attribute 
dataset: EvaluationDataset

Specifies the prompt dataset.

metric_names instance-attribute 
metric_names: list[str]

The names of the metrics you want to use for your evaluation job.

For knowledge base evaluation jobs that evaluate retrieval only, valid values are "Builtin.ContextRelevance", "Builtin.ContextCoverage".

For knowledge base evaluation jobs that evaluate retrieval with response generation, valid values are "Builtin.Correctness", "Builtin.Completeness", "Builtin.Helpfulness", "Builtin.LogicalCoherence", "Builtin.Faithfulness", "Builtin.Harmfulness", "Builtin.Stereotyping", "Builtin.Refusal".

For automated model evaluation jobs, valid values are "Builtin.Accuracy", "Builtin.Robustness", and "Builtin.Toxicity". In model evaluation jobs that use a LLM as judge you can specify "Builtin.Correctness", "Builtin.Completeness", "Builtin.Faithfulness", "Builtin.Helpfulness", "Builtin.Coherence", "Builtin.Relevance", "Builtin.FollowingInstructions", "Builtin.ProfessionalStyleAndTone", You can also specify the following responsible AI related metrics only for model evaluation job that use a LLM as judge "Builtin.Harmfulness", "Builtin.Stereotyping", and "Builtin.Refusal".

For human-based model evaluation jobs, the list of strings must match the name parameter specified in HumanEvaluationCustomMetric.

task_type instance-attribute 
task_type: str

The the type of task you want to evaluate for your evaluation job. This applies only to model evaluation jobs and is ignored for knowledge base evaluation jobs.
