Macro-Precision Metric

A Macro-Precision Metric is a macro-averaged performance measure that is a precision metric computed as the unweighted arithmetic mean of per-class precision scores.

• AKA: Macro-Precision, Unweighted Mean Precision, Class-Averaged Precision Measure.
• Context:
  • It can typically calculate Macro-Precision Score Values by computing individual macro-precision class-specific precisions and averaging them without weighting.
  • It can typically treat Macro-Precision Class Contributions equally regardless of macro-precision class frequency or macro-precision class support.
  • It can typically emphasize Macro-Precision Minority Class Performance as strongly as macro-precision majority class performance.
  • It can typically reveal Macro-Precision Model Weaknesses in macro-precision rare class predictions that macro-precision weighted metrics might obscure.
  • It can typically serve as a component for computing Macro-F1 Measures when combined with macro-recall metrics.
  • ...
  • It can often yield Macro-Precision Lower Values than micro-precision metrics in macro-precision imbalanced datasets.
  • It can often be sensitive to Macro-Precision Poor Performance in any single macro-precision class.
  • It can often be preferred when Macro-Precision Per-Class Fairness is more important than macro-precision overall accuracy.
  • It can often be combined with Macro-Precision Standard Deviations to show macro-precision performance variability.
  • ...
  • It can range from being a Low Macro-Precision Metric to being a High Macro-Precision Metric, depending on its macro-precision classification quality.
  • It can range from being a Uniform Macro-Precision Metric to being a Variable Macro-Precision Metric, depending on its macro-precision cross-class consistency.
  • It can range from being a Binary-Derived Macro-Precision Metric to being a Native Multi-Class Macro-Precision Metric, depending on its macro-precision computation approach.
  • It can range from being a Stable Macro-Precision Metric to being a Volatile Macro-Precision Metric, depending on its macro-precision temporal consistency.
  • ...
  • It can be calculated using Macro-Precision Formula: (1/n) × Σ(Precision_i) for n classes.
  • It can be visualized through Macro-Precision Performance Charts showing macro-precision per-class scores.
  • It can be tracked through Macro-Precision Monitoring Systems for macro-precision model evaluation.
  • It can be optimized using Macro-Precision Enhancement Techniques targeting macro-precision weak classes.

• Example(s):
  • Text Classification Macro-Precision Metrics, such as:
    • News Category Macro-Precision Metric for macro-precision news classification tasks.
    • Sentiment Analysis Macro-Precision Metric for macro-precision opinion mining tasks.
    • Language Detection Macro-Precision Metric for macro-precision multilingual tasks.
  • Image Classification Macro-Precision Metrics, such as:
    • Object Recognition Macro-Precision Metric for macro-precision visual detection tasks.
    • Scene Classification Macro-Precision Metric for macro-precision environment recognition tasks.
  • Biomedical Macro-Precision Metrics, such as:
    • Disease Classification Macro-Precision Metric for macro-precision diagnostic tasks.
    • Drug Discovery Macro-Precision Metric for macro-precision compound screening tasks.
  • ...
• Counter-Example(s):
  • Micro-Precision Metric, which aggregates true positives and false positives globally rather than averaging per-class precision.
  • Weighted Precision Metric, which applies class weights based on sample support rather than equal weighting.
  • Macro-Recall Metric, which measures per-class sensitivity rather than per-class precision.
  • Macro-F1 Measure, which combines macro-precision with macro-recall rather than measuring precision alone.
