[R] Applying Machine Learning and Discrete Choice Modeling to understand the quality of urban landscape
Wekun (wekun.ing.puc.cl) is a game that seeks to understand how people perceive public space and, thus, understand what determines the quality of these spaces.
We ask people to chose between images to measure their preferences. Then, the information collected is processed with Machine Learning algorithms and discrete choice models, in order to understand the role played by different elements of the built environment and nature in the preferences of people. The methodology is not new (links below), but we have incorporated a section to register sociodemographic information aiming to find heterogeneity among observers. We use Discrete Choice Modelling as a benchmark to Machine Learning Algorithms, typically referred to as black boxes, to overcome the explainability problems involved with them.
