Class ROCSerializer

java.lang.Object

org.nd4j.shade.jackson.databind.JsonSerializer<ROC>

org.nd4j.evaluation.serde.ROCSerializer

All Implemented Interfaces:

org.nd4j.shade.jackson.databind.jsonFormatVisitors.JsonFormatVisitable

public class ROCSerializer
extends org.nd4j.shade.jackson.databind.JsonSerializer<ROC>

Custom Jackson serializer for ROC. This is necessary to force calculation of the AUC and AUPRC metrics, so said metrics can be stored in the JSON; this is important for exact ROC, as if it's not present at the time of serialization, it cannot be calculated later, due to the underlying (very large) predictions no longer being present.
