Error Weighting Metric

An Error Weighting Metric is an error metric that assigns differential importance to errors based on severity, impact, or business risk.

• AKA: Weighted Error Measure, Severity-Based Error Metric, Risk-Adjusted Error Metric.
• Context:
  • It can typically prioritize High-Impact Errors with severity weights and risk factors.
  • It can typically distinguish Critical Errors from minor discrepancies through impact scoring.
  • It can typically support Risk-Based Evaluation via business impact assessment and compliance weighting.
  • It can often integrate into Risk-Weighted Scorecards with model error severity and quality metrics.
  • It can often enable Cost-Sensitive Learning through misclassification costs and error penaltys.
  • It can often inform Model Optimization by focusing improvement on high-weight errors.
  • ...
  • It can range from being a Low-Severity Error Weighting Metric to being a High-Severity Error Weighting Metric, depending on its error weighting impact threshold.
  • It can range from being a Binary Error Weighting Metric to being a Continuous Error Weighting Metric, depending on its error weighting granularity.
  • It can range from being a Static Error Weighting Metric to being a Dynamic Error Weighting Metric, depending on its error weighting adaptability.
  • It can range from being a Domain-Agnostic Error Weighting Metric to being a Domain-Specific Error Weighting Metric, depending on its error weighting application context.
  • ...
  • It can complement Mean Squared Error (MSE) Measure with weighted penaltys.
  • It can enhance Standard Error Measure through importance factors.
  • It can improve Root Mean Squared Error (RMSE) Metric via severity adjustment.
  • It can refine Word Error Rate (WER) Measure with linguistic importance.
  • It can augment Symmetric Mean Absolute Percentage Error through business criticality.
  • ...
• Example(s):
  • Severity-Weighted Error Metrics, such as:
    • Severity-Weighted Error, which applies severity coefficients to prediction errors.
    • Model Error Severity, which categorizes error impact levels.
    • Critical Error Penalty, which heavily penalizes safety-critical errors.
  • Cost-Based Error Metrics, such as:
    • Misclassification Cost Matrix, which assigns monetary costs to error types.
    • Business Impact Error Score, which weights by revenue impact.
    • Operational Risk Error Metric, which considers operational consequences.
  • Domain-Specific Weighted Errors, such as:
    • Medical Diagnosis Error Weight, which prioritizes false negatives in critical conditions.
    • Financial Risk Error Metric, which emphasizes regulatory violations.
    • Legal Document Error Weight, which focuses on liability-creating errors.
  • Adaptive Error Weights, such as:
    • Time-Sensitive Error Weight, which increases weight over time.
    • Context-Aware Error Weight, which adjusts based on application context.
    • User-Specific Error Weight, which personalizes error importance.
  • ...
• Counter-Example(s):
  • Unweighted Error Metric, which treats all errors equally regardless of impact.
  • Binary Error Count, which only counts presence/absence without weighting.
  • Simple Accuracy Metric, which doesn't differentiate error types or severity.
