GEOG 588 - Final Project: This project assesses the relationship between Airbnb listing distribution and mean household income across the Boston, Massachusetts neighborhoods. A rarely assessed relationship, this project closes the gap in understanding by combining US Census income data with that of Airbnb listings. This produced a process for assessing other variable relationships to Airbnb listing distribution. Utilizing exploratory analysis and linear regression, mean household income and Airbnb listing distribution was found to have no correlation. Utilizing the methodologies employed in this study, future analysis can be performed to expand the variables assessed to include greater demographic characteristics within each neighborhood.

This chapter introduces the concept of Unsupervised Learning through the lens of Data Clustering. Students will learn how to find "hidden structures" in data without predefined labels, mastering the techniques used to group similar observations together. From identifying customer segments to discovering natural patterns in biology, this chapter provides the tools to make sense of unlabeled datasets by letting the data speak for itself. Core Topics covered: Introduction to Clustering K-Means Clustering Hierarchical Clustering DBSCAN Cluster Validation Gaussian Mixture Models Practical Clustering Workflow Chapter Lab Activity: Customer Segmentation with wholesales Data
