|---|---|---|---|---|
| Facebook Prophet | PM2.5 | 4.3 | 5.4 | 0.94 |
| Facebook Prophet | PM10 | 4.0 | 4.6 | 0.96 |
| NeuralProphet | PM2.5 | 14.6 | 17.8 | 0.38 |
| NeuralProphet | PM10 | 10.0 | 16.1 | 0.56 |
| SARIMAX | PM2.5 | 17.1 | 18.0 | 0.41 |
| SARIMAX | PM10 | 13.7 | 14.9 | 0.64 |
| LSTM | PM2.5 | 38.8 | 40.0 | -2.49 |
| LSTM | PM10 | 10.6 | 17.6 | 0.44 |
| LightGBM | PM2.5 | 33.4 | 38.0 | -1.63 |
| LightGBM | PM10 | 144.0 | 154.5 | -37.30 |
Actionable Insights for Urban Air Quality Management
