A summary of published articles that used deep sequential models in environment and pollution predictions.
| Ref. | Method | Application | Results obtained | Metrics used | Data unit |
| [61] | Hybrid ANN + CSA | Environment pollution | The model was consistently outperforming control models. | Error = 24.1% | Monthly | [62] | Hybrid CEEMDAN-deep-TCNN | Environment pollution | The model shown to perform the best compared to time series models, ANN, and popular deep learning models. | MAPE, RMSE, MAE | Hourly | [63] | LSTM | Environment pollution | LSTM outperformed back-propagation in terms of prediction accuracy. | RMSE = 0.08 | Air pressure parameters | [64] | LSTM | Environment pollution | There is no “one-size-fits-all” approach that is effective in any city under any circumstance. | RMS = 30–40 ppm | Hourly | [65] | LSTM | Environment pollution | The LSTM model’s root mean square error is 5.58 | Average error was 5.58 by RMSE | Monthly | [66] | LSTM-BP | Environment pollution | The time series predicted by LSTM-BP was found to be more accurate | RMSE = 1.03. MAE = 0.68 MAPE = 3.37 | Daily | [67] | ANN | River flow | The model significantly increases when the lag 1 river flow is included as an input. | R2, MIA, RMSE, MNSE | Daily and monthly | [68] | Hybrid ICEEWT-IGWO-GRU | Streamflow | The proposed model outperformed the single GRU | MAE, RMSE | Monthly |
