Ensemble Method (using random forest and AdaBoost) with Validation code

[SaurabhIndi]

This code demonstrates a simple ensemble method using random forest and AdaBoost. It combines the predictions of these two models by taking their average. We can experiment with different ensemble techniques like stacking or voting, and adjust the hyperparameters of the individual models to find the best combination for our specific problem.
