초록 Indoor environment quality (IEQ) at subway stations is a complex system comprised of several factors with extremely non-linear patterns. To achieve sustainable IEQ levels accurate identification of future fine particulate matter (PM2.5) levels is crucial. However, numerous statistical and neural network models perform poorly to generate an accurate early warning mostly because of their deterministic nature. The current study presents a genetic algorithm enhanced gated transformer model for probabilistic forecasting of PM2.5 levels at a subway platform up to five hours ahead. The proposed framework surpasses numerous combinations of traditional time series models in terms of prediction interval probability and Winkler scores. In comparison to the deterministic model, missed health risk alarms were reduced by up to 72%.
