"Geo-Spotting: Mining Online Location-based Services for Optimal Retail Store Placement"

Venue: MYRA School of Business

Talk Summary: 

The problem of identifying the optimal location for a new retail store has been the focus of past research, especially due to its importance in the success of businesses. Traditional approaches to the problem have factored in demographics, revenue and aggregated human flow statistics from nearby or remote areas. However, the acquisition of relevant data is usually expensive. With the growth of location-based social networks, fine-grained data describing user mobility and popularity of places have recently become attainable.
In this talk, Dr.Karamshuk would focus on the predictive power of various machine learning features in making decisions regarding the location of retail stores. Based on his research on the popularity of retail stores in the city through the use of a dataset collected from Foursquare in New York, he is going to lay out how data mining can help make business decisions. The features they mined in their study included two general signals: geographic, where features are formulated according to the types and density of nearby places, and user mobility, which includes transitions between venues or the incoming flow of mobile users from distant areas. Their research suggests that the best performing features are common across the three different commercial chains considered in the study—Starbucks, Dunkin’ Donuts and McDonalds, although variations may exist too, as explained by heterogeneities in the way retail facilities attract users. We also show that performance improves significantly when combining multiple features in supervised learning algorithms, suggesting that the retail success of a business may depend on multiple factors.
