Course Introduction：In order to build reliable machine learning models, splitting of data sets is essential. The splitting process involves dividing the data set into training, validation, and test sets. This article aims to introduce in detail the concepts of these three collections, data splitting techniques, and pitfalls that can easily occur. Training Set, Validation Set, and Test Set Training Set A training set is a data set used to train and enable the model to learn hidden features/patterns in the data. In each epoch, the same training data is repeatedly fed into the neural network architecture, and the model continues to learn the characteristics of the data. The training set should have a diverse set of inputs so that the model is trained on all scenarios and can predict possible future data samples. Validation set A validation set is a set of data, separate from the training set, used to verify model performance during training.
