While accuracy provides a general overview of the model’s performance, it may not be suitable for imbalanced datasets or certain tasks, such as anomaly detection.
2. Precision and Recall: Precision and recall are evaluation metrics commonly used in binary classification tasks. Precision represents the fraction of true positive predictions out of all positive predictions, while recall measures the fraction of true positive predictions out of all actual positive instances. These metrics are particularly useful in cases where false positives or false negatives have different consequences.
3. F1 Score: The F1 score is a weighted combination of precision and recall, providing a balanced evaluation metric that considers both true positives and false positives. It is the harmonic mean of precision and recall, indicating the overall performance of a model in binary classification tasks. The F1 score is useful when there is an imbalance between positive and negative instances in the dataset.
4. Mean Average Precision (mAP): mAP is a popular evaluation metric in object detection and image retrieval tasks. It measures the accuracy of locating objects or retrieving similar images by considering precision at various recall levels. The mAP summarizes the model’s performance across different object categories or query images, providing a comprehensive measure of its effectiveness.
5. Mean Squared Error (MSE): MSE is commonly used in regression tasks to evaluate the closeness of predicted values to the ground truth. It calculates the average of the squared differences between predicted and actual values. A lower MSE value indicates better performance, with predictions closer to the true values. However, MSE may not be suitable for all regression tasks, especially when outliers are present.
6. Area Under the Curve (AUC): AUC is an evaluation metric used in binary classification tasks to measure the overall performance of a model’s classification predictions. It represents the ability of a model to distinguish between positive and negative instances, considering various decision thresholds. A higher AUC score indicates better discrimination and superior performance.
7. Mean Average Precision at K (mAP@K): mAP@K is commonly used in information retrieval tasks, such as search engines or recommendation systems. It evaluates the relevance of the top-K predictions made by a model compared to the ground truth. The mAP@K provides insights into the model’s ability to retrieve relevant results within the top-K predictions, reflecting its effectiveness in real-world scenarios.
