precision-recall
Precision and recall are fundamental metrics used to evaluate the performance of classification algorithms in machine learning and information retrieval. Precision measures the accuracy of positive predictions, indicating how many of the predicted positive instances are actually correct. In contrast, recall assesses the model’s ability to identify all relevant instances, reflecting how many actual positive cases were correctly predicted. Understanding the balance between precision and recall is crucial, as improving one often leads to a decrease in the other. These metrics are particularly important in scenarios where the cost of false positives and false negatives varies significantly.
Precision & Recall — An Illustrative
Precision & Recall — An Illustrative Precision is defined as TP / (TP + FP), while Recall is defined as TP / (TP + FN). Clearly, Precision is maximised when FP = 0, while Recall is maximised when FN ...
