Apa ini Cross- Validation?
Cross--validation tidak ada pembagian ke yang lain. Ini most commo paras ik k-fold pardation, whene dates splig oc oor other.
Types of Cross- Validation
- Pertama, FLT: 0; 0 = 3. K-Fold Cross - Validation:
- Pertama; FLT: 0 = 33; Stratied K-Fold:
- Pertama; FLT: 0 ASA3; One3; Leave-OUT (LOO): S01; FLT: 1: 1 FLT; Uses one data point for validation and the rest for traing, repeted for each point.
- Pertama, FLT: 0 = 33. Repeat3; Repeated Cross - Validation:

Benefits of Cross- Validation
- Provides a more prestimate of model perforce ce.
- Helps is tuning hyperparameters efektivy.
- Reduces the risk of overfitting.
- Utilizes data efisiciently, expericially with smalil datsets.
