I am working on a transactional dataset where I am trying to create a churn prediction model using SVM. I have manually defined my training and testing dataset and have not used CrossValidation.
However, to find the best hyperparameters for my SVM(svc) model, is there any alternative way to do it without Grid Search CV, my objective here is to try and prevent any data leakage happening as I understand that using CV wouldn't solve that problem.
