Скачать или смотреть The Purpose of Train-Test Split in Machine Learning | How to Correctly Split Data?

🔥 In this video we discuss one of the most important concepts in machine learning called: train-test split. Through clear visualizations, we explain the significance of splitting the data into train and test sets and how separate subsets should be properly used. Test data is used for final model evaluation, meaning that it should not be used in any other stage. Validation set is used for model selection and configuration, which is a topic we will talk about in the upcoming videos.
