To prepare an (a core task in machine learning and data analysis), you must follow a systematic process of identifying, extracting, and selecting the variables that best describe the underlying patterns in your data. 1. Define the Objective Select the one with the best accuracy

Convert raw, unstructured data into a numerical format that a model can process.

: In specialized fields, this involves searching for key classifying features within a specific area that characterize its unique properties. 3. Feature Selection (Iterative Process)
