IoT based Smart Farming : Feature subset selection for optimized high dimensional data using improved GA based approach for ELM

Agriculture is one of the major backbones of Indian economy where around 60% of people are depending directly or indirectly upon agriculture. The expert advice is required for distinguishing the plant disease damage and nutrient imbalance. It is observed that, the conventional judgmental analysis is not enough while deciding the quantity of chemical or fertilizer to be used. The mis-proportional dose harms the health of the crop and hence the living beings. To overcome the said problem, this paper proposes an Internet of things (IoT) based Smart Farming decision support system with an improved genetic algorithm (IGA) based multilevel parameter optimized feature selection algorithm for ELM classifier (IGA-ELM). The proposed work is applied to benchmark high dimensional biomedical datasets as well as for real time applications (plant disease dataset) which provides 9.52% and 5.71% improvement in the classification accuracy by reducing 58.50% and 72.73% features respectively. Simulation results demonstrate that IGA-ELM has the capability to handle optimization, uncertainty and supervised binary classification problems with improved classification accuracy even though reduced the number of features.
