In this short course, I walk you through an introduction to data science and machine learning in Python using the classic Iris Dataset. You'll learn through doing, all in a single Jupyter Notebook.
In this video, you'll learn:
- What cross-validation is.
- How to implement cross-validation using cross_val_score and cross_val_predict.
- How to identify where we're misclassifying data points (getting the prediction wrong).
