Final answer:
The online platform uses a Data Mining algorithm to recommend pillows based on your bed purchase by analyzing your buying patterns and suggesting items that are commonly bought together.
Step-by-step explanation:
When you are shopping online and the platform recommends pillows after you purchase a bed, the algorithm it is using is an example of Data Mining. Data mining algorithms analyze your purchasing habits and the items you are viewing or have bought to make personalized recommendations. This process relies on patterns and relationships in the data, such as products commonly bought together or items that share certain attributes.
Online retailers use this sophisticated approach to improve the shopping experience by suggesting additional items that customers might find useful or desirable. These recommendations can lead to increased sales and customer satisfaction as they often help consumers discover products that they may not have found by themselves.
