K fold cross validation on iris dataset

Web7 mrt. 2024 · We will evaluate our model by K-fold cross-validation with 10 folds. The following code will split our dataset into training and test folds and will evaluate our model performance 10 times. Trick !!! WebK-fold cross-validation is a special case of cross-validation where we iterate over a dataset set k times. In each round, we split the dataset into k parts: one part is used for validation, and the remaining k − 1 parts are merged into a training subset for model evaluation. The figure below illustrates the process of 5-fold cross-validation:
