com.tnsai.evaluation.autoharness.SimpleFailureClusterer

All Implemented Interfaces:

FailureClusterer

public final class SimpleFailureClusterer
extends Object
implements FailureClusterer

Groups FailureRecords by errorType + phase.

This is the simplest clustering strategy: failures with the same error class occurring in the same phase are considered the same root cause. Each cluster retains up to maxExamples representative records.

Since:

0.1.0
