SQL Identity Key ,T-SQL

Microsoft SQL Server?s identity column generates sequential values for new records using a seed value. Seeding and reseeding an identity column is easy and relatively safe, if you do it correctly. Susan Sales Harkins shows you how it works.

Training Set, Validation Set, Test Set

Training Set is a subset of the dataset used to build predictive models.
Validation Set is a subset of the dataset used to assess the performance of model built in the training phase
– It provides a test platform for fine-tuning model’s parameters and selecting the best performing model
– Not all modeling algorithms need a validation set
Test set or unseen examples is a subset of the dataset to assess the likely future performance of a model.
– If a model fits the training set much better than it fits the test set. Overfitting is probably the cause
