Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
How to Use Metrics for Deep Learning With Keras in Python This can be technically challenging. A much simpler alternative is to use your final model to make a prediction for the test dataset, then calculate any metric you wish using the scikit-learn metrics API. Three metrics, in add...
In other words, if you randomly select one observation from each class, what’s the probability that your model will be able to “rank” them correctly? We can import this metric from Scikit-Learn: Python 1 from sklearn.metrics import roc_auc_score To calculate AUROC, you’ll need predi...
Before any modification or tuning is made to the XGBoost algorithm for imbalanced classification, it is important to test the default XGBoost model and establish a baseline in performance. Although the XGBoost library has its own Python API, we can use XGBoost models with the scikit-learn API vi...
There can be confusion in applied machine learning about how to train a final model. This error is seen with beginners to the field who ask questions such as: How do I predict with cross validation? Which model do I choose from cross-validation?
