8.
You are a Data Scientist working for a retail company interested in predicting customer purchasing behavior. You have access to a dataset containing customer demographics, purchase history, and browsing behavior on the company's website. Your task is to build a machine learning model that can predict which products a customer is likely to buy based on their profile and behavior. Given the scenario provided, which step of the machine learning workflow involves assessing the model's performance and iteratively fine-tuning it until satisfactory results are achieved?
Choose the correct answer.
Data Extraction
Dataset Partitioning
Training an ML Model
Model Evaluation
