"WebNov 27, 2024 · The current "best practice" is to make three subsets of the dataset: training, validation, and "test". When you are happy with the model, try it out on the "test" dataset. The resulting accuracy should be close to the validation dataset. If the two diverge, there is something basic wrong with the model or the data. Cheers, Lance Norskog.
