What problem is Angela trying to solve by grouping shoppers based on their shopping habits?

Angela is attempting to solve a problem related to unsupervised learning by grouping shoppers based on their shopping habits. Unsupervised learning is a type of machine learning that seeks to find patterns or groupings in data without having predetermined labels or categories. In this scenario, Angela does not have predefined labels for different shopper categories; instead, she is analyzing the data to discover natural groupings among shoppers based on their behaviors.

By employing clustering techniques often utilized in unsupervised learning, she can group shoppers who exhibit similar shopping habits, facilitating targeted marketing strategies or inventory decisions. This approach allows for insights derived directly from the data itself rather than relying on known outcomes, which is characteristic of supervised learning methodologies.
