Metric
In Data Science, a metric is a quantitative measure used to assess the performance of a model or algorithm. Metrics are used to evaluate how well a model is performing in terms of accuracy, precision, recall, F1 score, AUC-ROC, and other performance indicators. Metrics are essential in machine learning and deep learning models, as they help to determine the effectiveness of the model in solving a particular problem. Metrics are also used to compare different models and select the best one for a particular task. Choosing the right metric is crucial, as it can affect the performance of the model and the accuracy of the results. In addition, metrics can be used to monitor the performance of a model over time and identify areas for improvement.
