Frequent Traveler: Definition, Features, Modeling, and Product Use

Context: You are a data scientist at a professional networking platform. Using user activity and coarse location signals (e.g., city-level geolocation from login/IP/GPS, timezone), define and operationalize a “frequent traveler,” propose features and models to identify them, and discuss product applications and pitfalls.

1. How would you define a “frequent traveler”?
2. Which data points or features would you use to identify frequent travelers?
3. Why is it important to consider both frequency and distance of location changes rather than just frequency alone?
4. Once you’ve identified frequent travelers, how can you use this information in a product or service?
5. What analytical or modeling approaches might you use to classify users as frequent travelers?
6. What pitfalls might arise if you only focus on the frequency of location changes without considering distance?
