Absolute Performance Measure

An Absolute Performance Measure is a performance measure that measures system performance against fixed standards or objective criterions without relative comparisons to other systems or human baselines.

• AKA: Standalone Performance Measure, Non-Comparative Measure, Objective Performance Measure, Fixed-Standard Measure.
• Context:
  • It can typically provide Consistent Measurements across evaluation contexts.
  • It can typically use Predefined Thresholds for performance assessment.
  • It can often enable Historical Tracking of system improvements.
  • It can often support Requirement Verification against specifications.
  • It can facilitate Cross-Domain Comparisons using universal scales.
  • It can eliminate Reference Dependency simplifying evaluation setup.
  • It can reduce Evaluation Variance from human baseline variation.
  • It can integrate with Automated Testing Frameworks for continuous evaluation.
  • It can range from being a Binary Absolute Measure to being a Continuous Absolute Measure, depending on its value space.
  • It can range from being a Single-Dimension Absolute Measure to being a Multi-Dimension Absolute Measure, depending on its measurement scope.
  • It can range from being a Task-Specific Absolute Measure to being a General Absolute Measure, depending on its application breadth.
  • It can range from being a Threshold-Based Absolute Measure to being a Scale-Based Absolute Measure, depending on its scoring method.
  • ...
• Examples:
  • Accuracy-Based Measures, such as:
    • Classification Accuracy for prediction correctness.
    • Exact Match Score for string equality.
    • F1 Score for precision-recall balance.
  • Error-Based Measures, such as:
    • Mean Squared Error for regression tasks.
    • Word Error Rate for transcription quality.
    • BLEU Score for translation quality.
  • Efficiency Measures, such as:
    • Inference Time for speed measurement.
    • Memory Usage for resource consumption.
  • ...
• Counter-Examples:
  • Human Parity Measure, which requires human comparison.
  • Relative Performance Measure, which compares system-to-system.
  • Preference-Based Measure, which uses subjective judgment.
