Abstract

Plant diseases can severely degrade the quality and productivity of any crop. Hence, an automated forecasting model can be developed to help the farmers and agricultural experts for early detection and on-time treatment of plant diseases. However, precise identification and classification of plant diseases becomes tedious when the dataset is small-sized. This motivated us to design a feature extraction technique that can produce more relevant features for small-sized datasets by performing some operations on the original features. Thus, the current study contributes towards an accurate and speedy detection of plant diseases by proposing an innovative technique, namely, Fractional Mega Trend Diffusion (FMTD) function-based feature extraction technique. The proposed feature extraction technique, i.e., FMTD Function-based Fuzzy Transformation (FFFT) extends a small dataset into a high dimensional feature space by computing new features using a novel FMTD function. In this research, two small plant diseases datasets, namely Tomato Early Blight Disease (TomEBD) and Tomato Powdery Mildew Disease (TPMD) have been used to validate the proposed approach. Resampling techniques have also been implemented in this paper to balance the imbalanced datasets and afterwards, Optimized Kernel Extreme Learning Machine (OKELM) algorithm has been used for the classification purpose. A genetic algorithm has also been used for parameter optimization while performing feature extraction and classification. The results of this study indicate that the proposed approach has achieved the accuracy ranging between 70 and 89.47% for the TomEBD dataset and between 92.27 and 100% for the TPMD dataset. The performance of the proposed approach is also tested for its efficiency using three benchmarking datasets. Conclusively, the proposed approach performed remarkably well for all the three datasets.
