Accuracy: Overall percentage of correct predictions.
Top-k Accuracy: Accuracy considering the top-k predictions (e.g., Top-5 accuracy).
Precision: Ratio of true positive predictions to all positive predictions.
Recall (Sensitivity): Ratio of true positives to actual positives in the data.
F1 Score: Harmonic mean of precision and recall.
Area Under the ROC Curve (AUC-ROC): Measures model performance across various thresholds.
Area Under the Precision-Recall Curve (AUC-PR): Measures model performance on imbalanced datasets.
Log Loss (Cross-Entropy Loss): Evaluates the confidence of predictions with the true labels.
Mean Absolute Error (MAE): Average absolute difference between predicted probabilities and actual labels.
Mean Squared Error (MSE): Average squared difference between predicted and actual labels.
Confusion Matrix: Matrix displaying true positives, true negatives, false positives, and false negatives.
Balanced Accuracy: Average of recall obtained in each class, useful for imbalanced datasets.
Matthews Correlation Coefficient (MCC): Measures correlation between predicted and actual labels; robust for imbalanced datasets.
Kappa Statistic (Cohen’s Kappa): Measures agreement between predictions and actual labels, correcting for chance.
Brier Score: Measures the accuracy of probabilistic predictions, sensitive to calibration.
Expected Calibration Error (ECE): Measures the difference between predicted probabilities and actual accuracy.
Classification Calibration Error (CCE): A recent measure (post-2023) evaluating how well the probability outputs are calibrated for each class.
Uncertainty Calibration Error (UCE): Post-2023 measure for uncertainty calibration in models, especially in high-dimensional classes.
Jaccard Index (Intersection over Union): Measures similarity between prediction and ground truth.
True Skill Statistic (TSS): Useful for evaluating models on unbalanced data, balancing sensitivity and specificity.
Hinge Loss: A metric used primarily with SVMs, but applied here for multiclass classifications.
Average Precision (AP): Precision averaged across recall levels, especially useful in object-centric classification tasks.
False Positive Rate (FPR): Rate of incorrect positive predictions among all negative samples.
False Negative Rate (FNR): Rate of missed positive predictions among all actual positive samples.
Negative Log Likelihood (NLL): Evaluates model’s confidence in the correct class, with lower values indicating better performance.
Focal Loss: A metric that down-weights easy examples and focuses more on hard-to-classify examples, widely used for imbalanced datasets.
Out-of-Distribution (OoD) Detection Accuracy: Evaluates the model’s ability to identify samples outside the training data classes (post-2023).
Entropy: Measures the uncertainty of model predictions, with higher entropy indicating less confident predictions.
Lift (Gains): Assesses model improvement over random guessing, especially in classifying rare classes.
False Discovery Rate (FDR): Fraction of false positives among all positive predictions, useful for imbalanced classes.
