WebSep 9, 2024 · I was performing a binary classification problem with 15000 RGB images using a scratch build CNN model. While it comes to evaluate the model, I can do it in two ways: Splitting data Train and Test and use 10 fold cross-validation for the training data. Later with the best model, I would use the unseen Test data. WebMar 15, 2024 · And we also use Cross-Validation to calculate the score (MSE) for a given set of hyperparameter values. For any set of given hyperparameter values, this function returns the mean and standard deviation of the score (MSE) based on cross-validation. You can see the details in the Python code below.
