Machine Learning Metrics
Machine Learning Metrics are quantitative measures used to evaluate the performance, accuracy, and effectiveness of machine learning models. They provide objective criteria to assess how well a model predicts outcomes, classifies data, or performs tasks, enabling comparison between different models or iterations. Common metrics include accuracy, precision, recall, F1-score, and mean squared error, tailored to specific problem types like classification, regression, or clustering.
Developers should learn and use machine learning metrics to validate and optimize models during training, testing, and deployment phases, ensuring they meet business or research goals. For example, in a medical diagnosis application, high recall might be prioritized to minimize false negatives, while in a spam filter, precision could be more critical to avoid false positives. Metrics help in hyperparameter tuning, model selection, and communicating results to stakeholders.
