Adaptive Pricing with Machine Intelligence
1 like3,527 views
This document discusses using machine learning and fuzzy logic for adaptive pricing in e-commerce. It describes fuzzy logic as an option for adaptive pricing that uses intuitive business rules rather than large datasets. Fuzzy logic allows pricing to vary smoothly based on multiple factors like product popularity, user recency, and market penetration. The document provides examples of how these input factors could map to an output discount percentage using fuzzy rules and explains how fuzzy logic could integrate with store software for adaptive pricing.
