  2. Data Pipeline for Machine Learning

Problem Definition

This step constitutes identifying the right questions for the ML model to answer. The problem is defined to meet the expectations and needs of the decision-maker. They revolve around the data properties such as size, type, and type of machine learning algorithm preferred. In this step, it is important to determine the input and output variables for the ML algorithm along with any weighing schemes that might be adapted based on the importance of the variables.
