Answer: Defining the problem type (e.g., classification, regression, clustering) based on the business objective, Identifying the target variable that needs to be predicted or classified
Correct Answers: C. Defining the problem type (e.g., classification, regression, clustering) based on the business objective and E. Identifying the target variable that needs to be predicted or classified. Explanation: In the initial phase of defining a machine learning problem, it is crucial to accurately identify the problem type and the target variable. This involves: - **Understanding the Business Objective**: Clearly articulating the goal of the ML solution, which in this case is predicting customer churn. - **Identifying the Target Variable**: Determining what needs to be predicted or classified, such as whether a customer will churn or not. - **Selecting the Appropriate Problem Type**: Choosing the right ML algorithm based on the target variable and the problem's nature, such as classification for predicting churn. These steps ensure that the subsequent stages of the ML project, including model selection and training, are aligned with the business goals. Incorrect Options: - **A. Conducting exploratory data analysis**: While important for understanding the data, it is not the first step in defining the ML problem. - **B. Selecting the appropriate machine learning model for training**: This step comes after the problem has been defined. - **D. Setting up the data storage infrastructure**: This is a technical task related to data engineering, not the core responsibility of defining the ML problem.
