4. 제목: Improvement of land use regression method as sign constrained regularized regressions

5. 초록: Land-use regression is a popular method for predicting ambient pollutant concentrations at points of interest where no measurements are taken. However, the model-building process is complicated, and systematically understanding when and how the process works is difficult. To overcome these limitations, we reformulate the existing land use regression method as a sign-constrained regression problem with an explicit objective function to be minimized. In this study, we propose a modification of the penalized regression methods to satisfy domain knowledge-based sign constraints.
