SDGs | Field | Main finding | References |
---|---|---|---|
SGD 2 (Zero Hunger) | Agriculture | Partial Least Square Regression was applied with success, as a FS method, on crop yield estimation | [115] |
The FS results demonstrated that the proposed Maximum Separability and Minimum Dependency method was more accurate than filter methods | [116] | ||
SGD 6 (Clean Water and Sanitation) | Water resources | The proposed approach proved to be effective and accurate to assess water resources at catchment scale | [117] |
Water Sources | Stepwise Discriminant Analysis and PCA improved the accuracy of water source recognition | [118] | |
SDG 7 (Affordable and Clean Energy) | Electricity | The proposed method improved the forecasting of electricity price and it was more accurate than the Independent Electricity System Operator prediction | [119] |
SGD 9 (Industry, Innovation and Infrastructure) | Structural Reliability | The Bivariate Dimension Reduction Method proved to be effective for structural reliability analysis | [120] |
SGD 11 (Sustainable Cities and Communities) | Land Cover | The results demonstrated that FS improves the classification accuracy of land cover classification | [121] |
The proposed method demonstrates better results compared to other methods for land cover classification in almost all tests | [122] | ||
Dimensionality Reduction was considered a key step in the land cover classification process | [123] | ||
The experiments shown that the impervious surface extraction accuracy of Classification and Regression Tree was higher than Seperability and Thresholds algorithm | [124] | ||
Land use | FS with Classification Optimisation Score metric reduces the processing time and produces higher classification accuracy for land use and land cover classification using VHR data | [125] | |
SDG 13 (Climate Action) | Pollution | The new Dimension Reduction method demonstrated to be a powerful approach to optimise the knowledge that emerges from atmospheric observations of N2O | [126] |
SGD 15 (Life on Land) | Forest | Proposed a FS SVM-Recursive Feature Elimination method to explore the relationship between the biomass and parameters derived from Landsat-8 imagery. The results demonstrated that this method was able to accurately estimate the aboveground biomass. | [127] |
Terrestrial ecosystem | FS methods allow the extraction of valuable information to create accurate maps of areas infested by invasive plant species | [128] |
