INTRODUCTION: The Bank Marketing dataset involves predicting the whether the bank clients will subscribe (yes/no) a term deposit (target variable). It is a binary (2-class) classification problem. There are over 45,000 observations with 16 input variables and 1 output variable. There are no missing values in the dataset.

CONCLUSION: The baseline performance of the 11 algorithms achieved an average accuracy of 89.13%. Three algorithms (Stochastic Gradient Boosting, Random Forest, and AdaBoost) achieved the top accuracy and Kappa scores. The top result achieved using the training data was from Stochastic Gradient Boosting. It achieved an average accuracy of 91.00% after a series of tuning trials, and its accuracy in processing the validation dataset was 90.58%. For this project, the Stochastic Gradient Boosting ensemble algorithm yielded consistently top-notch training and validation results, which warrant the additional processing required by the algorithm.
