In Machine Learning, accuracy, precision, and recall are crucial evaluation metrics that assess a model's ability to make correct predictions in classification tasks. Accuracy measures overall correctness across all classes, while precision focuses on correctly predicted positive instances and minimizes false positives. Recall emphasizes the model's ability to identify all relevant instances and minimize false negatives. Understanding these metrics is essential for real-life situations, especially in binary and multi-class classification problems with imbalanced datasets. The confusion matrix provides a visual representation of correct predictions, and the precision-recall curve showcases the trade-off between precision and recall for different threshold settings. Choosing between precision and recall depends on the application's specific needs and the cost of errors, making it essential to evaluate models and adjust thresholds accordingly.
