What is a common split?
80% train, 20% test.
Split the data
| Training set: model learns |
| Testing set: kept hidden |
| Often 80% and 20% |
Remember
| Test only on unseen data |
Your model scores ninety nine percent. Should you trust it? Only if tested fairly. The model learns from the training set. The testing set stays hidden. A common split is eighty and twenty. Test only on data the model has not seen.
