What is cross-validation and its types?
Cross-validation is a machine learning technique where the training data is split into two parts: A training set and a test set. The training set is used to build the model, and the test set is used to evaluate how well the model performs when in production.
What do you mean by cross-validation?
Definition. Cross-Validation is a statistical method of evaluating and comparing learning algorithms by dividing data into two segments: one used to learn or train a model and the other used to validate the model.
What is cross-validation and validation machine learning?
Cross-validation is a technique for validating the model efficiency by training it on the subset of input data and testing on previously unseen subset of the input data. We can also say that it is a technique to check how a statistical model generalizes to an independent dataset.
What is cross-validation example?
For example, setting k = 2 results in 2-fold cross-validation. In 2-fold cross-validation, we randomly shuffle the dataset into two sets d0 and d1, so that both sets are equal size (this is usually implemented by shuffling the data array and then splitting it in two).
