Lessons from a Human-in-the-Loop Machine Learning Approach for Identifying Vacant,Abandoned,and Deteriorated Properties in Savannah,Georgia

Abstract

Addressing strategies for managing vacant, abandoned, and deteriorated (VAD) properties is important for maintaining healthy communities. Yet, the process of identifying these properties can be difficult. Here, we create a human-in-the-loop machine learning (HITLML) model called VADecide and apply it to a parcel-level case study in Savannah, Georgia. The results show a higher prediction accuracy than was achieved when using a machine learning model without human input in the training. The HITLML approach also reveals differences between machine versus human-generated results. Our findings contribute to knowledge about the advantages and challenges of HITLML in urban planning.
