Pii Metric¶
- pydantic model ibm_watsonx_gov.metrics.pii.pii_metric.PIIMetric¶
Bases:
GenAIMetricDefines the PII metric class.
The PII metric measures measures if your model input or output data contains any personally identifiable information in the input. It is computed using the Watson Natural Language Processing entity extraction model.
Examples
- Create PII metric with default parameters and compute using metrics evaluator.
metric = PIIMetric() result = MetricsEvaluator().evaluate(data={"input_text": "...", metrics=[metric])
- Create PII metric with a custom threshold.
threshold = MetricThreshold(type="lower_limit", value=0.5) metric = PIIMetric(threshold=threshold)
