Addressing Feature Scarcity and Bias
Sensor-based agricultural datasets often suffer from a limited number of features due to the high cost and complexity of continuous sensor deployment. Existing feature extraction methods frequently depend on class variables, leading to information leakage and biased model evaluations, especially in real-time prediction scenarios where class labels are unknown.
The research introduces a novel Membership Function-based Feature Extraction (MFFE) technique designed to operate entirely independent of class variables. By utilizing reformed triangular and Gaussian membership functions, it transforms existing features into a richer, unbiased set, computing all necessary parameters solely from the training data. This ensures robust and fair model evaluation, making it highly applicable for real-time disease detection in dynamic agricultural environments.
Class-Independent Feature Engineering & Optimized Learning
The methodology begins with balancing imbalanced datasets using the KMeans-SMOTE technique, ensuring representative sample distribution. For feature extraction, reformed Triangular and Gaussian Membership Functions (TMF/GMF) are applied, with all parameters (like mean, variance, lower/upper limits) derived exclusively from the training data. This critical step prevents information leakage and ensures class-independent feature transformation.
The enhanced datasets are then fed into two optimized machine learning models: Optimized Kernel Extreme Learning Machine (OKELM) and Optimized Radial Basis Function Neural Network (ORBFNN). These models are fine-tuned using the Optuna framework, which employs Bayesian optimization for efficient hyperparameter tuning, maximizing accuracy while reducing computational cost. The entire framework is designed for generalization and reliability across diverse datasets.
Superior Accuracy and Robust Generalizability
The study's comprehensive evaluation revealed that the TMF-ORBFNN model consistently achieved the highest accuracy across both plant-disease and diverse non-plant benchmark datasets. For instance, it reached 87.02% accuracy on the TomEBD dataset (tomato early blight) and an impressive 98.85% on the TPMD dataset (tomato powdery mildew).
Statistical analysis using the Friedman test and post-hoc Bonferroni-Dunn test confirmed that TMF-ORBFNN performed significantly better than its counterparts. The proposed class-independent feature extraction, combined with optimized ORBFNN, provides a lightweight, efficient, and reliable solution for timely disease prediction. This ensures farmers can take preventative measures with minimal pesticide use and improved crop quality, safeguarding agricultural productivity.

Case Study: Optimizing Tomato Crop Health with Predictive AI
A large-scale agricultural enterprise specializing in tomato production faced significant challenges with early blight and powdery mildew. Traditional detection methods were slow and reactive, leading to widespread disease, excessive pesticide use, and substantial yield losses.
Challenge: Inaccurate and late disease predictions, high operational costs due to broad-spectrum pesticide application, and difficulty scaling detection across vast fields with limited sensor data.
Solution: Implementing a real-time sensor network integrated with the TMF-ORBFNN predictive model. The class-independent MFFE technique enabled the system to extract robust features from small sensor datasets without prior knowledge of disease labels, even in new environmental conditions. The Optuna-optimized model provided highly accurate, timely predictions of disease conducive conditions.
Result: Within the first season, the farm observed a 20% reduction in pesticide usage due to targeted applications, a 15% increase in healthy crop yields, and a 75% faster response time to initial disease indicators. The system's generalizability meant it could be rapidly scaled across different tomato varieties and environmental zones, significantly improving overall crop management efficiency and profitability.
