Solution
When working on modeling, it is generally recommended to split the data into separate sets for training and testing. This allows you to evaluate the performance of your model on unseen data and avoid overfitting.
If you choose to split the data, there are several options for the proportions of the splits:
-
Train and Test, since Validation is not always required - In this case, you can split the data into a training set and a testing set. A common split is 70% for training and 30% for testing.
-
Train and Test and Validation - If you want to include a validation set, you can split the data into three sets: training, testing, and validation. A common split is 60% for training, 20% for testing, and 20% for validation.
-
Only Train - Alternatively, you may choose to use only a training set and not have a separate testing or validation set. In this case, you would use all of the available data for training your model.
-
Train and Validation - Another option is to have a training set and a validation set, without a separate testing set. A common split is 70% for training and 30% for validation.
The choice of the split proportions depends on the specific requirements of your modeling task and the available data. It is important to consider factors such as the size of the dataset, the complexity of the model, and the need for unbiased evaluation.

3. Why do you split data into training and validation sets? Data is split into two sets in order to create two models, one model with the training set and a different model with the validation set.Splitting data into two sets enables you to train the model with the training set and test the model on unseen data from the test set.Only split data when you use the Azure Machine Learning Designer, not in other machine learning scenarios.
