A validation data set is a data-set of examples used to tune the hyperparameters (i.e. the architecture) of a classifier. It is sometimes also called the development set or the "dev set". An example of a hyperparameter for artificial neural networks includes the number of hidden units in each layer. It, as well as the testing set (as mentioned below), should follow the same probability distribution as the training data set. WebThen, you use .read_csv () to read in your dataset and store it as a DataFrame object in the variable nba. Note: Is your data not in CSV format? No worries!
