This module introduces learners to the foundational steps of building a predictive model in a real-world banking context. It begins by clearly defining the business problem of predicting customer subscription to a term deposit product. The module then guides learners through understanding the dataset, exploring key variables using Exploratory Data Analysis (EDA), and preparing the data for modeling by handling missing values and selecting relevant features. By the end of the module, learners will be equipped with essential data preprocessing skills and the ability to frame analytical problems for machine learning applications.

This module equips learners with the tools and techniques required to build, assess, and improve predictive models. It begins with the development of models using Information Value and multicollinearity checks to select the right variables. Learners then explore techniques to assess model performance using ranking tables, the Kolmogorov-Smirnov (KS) statistic, AUC, and Lift metrics. The module concludes with optimization strategies such as monotonicity adjustment and decision tree refinement, followed by validation and deployment of the model to unseen datasets. By the end of the module, learners will be proficient in developing, evaluating, and preparing models for production environments.
