Evaluate model performance using metrics from "summary" of Python for Data Analysis by Wes McKinney
Model performance evaluation is a crucial aspect of any data analysis project. Once a model has been trained on a dataset, it is essential to determine how well it performs on new, unseen data. This evaluation process helps in assessing the effectiveness of the model in making predictions and understanding its strengths and weaknesses. To evaluate model performance, various metrics can be used. These metrics provide quantitative measures of how well the model is performing based on different criteria. Commonly used metrics include accuracy, precision, recall, F1 score, and ROC-AUC. Each metric focuses on different aspects of model performance and can provide valuable insights into the model's behavior. Accuracy is a simple and intuitive metric that measures the proportion of correctly classified instances out of all instances. While accuracy is useful, it may not be sufficient in cases where the dataset is imbalanced. In such situations, precision, recall, and F1 score can provide a more nuanced understanding of the model's perfo...
