Machine Learning Algorithms for Soil Nutrient Prediction:
- Random Forest, Support Vector Machine (SVM), Decision Tree, Naïve Bayes, and Artificial Neural Network (ANN) are commonly used algorithms for predicting soil properties. However, no single method consistently outperforms others across all scenarios .
- Extreme Learning Machine (ELM) with different activation functions, particularly the gaussian radial basis function, shows high accuracy in classifying soil parameters .
-
Multi-Component vs. Single-Component Prediction:
- Multi-component strategies for nutrient characterization yield better prediction accuracy compared to single-component approaches .
-
Spectroscopic Methods:
- Combining optical spectroscopy with electrical impedance spectroscopy can improve prediction accuracy. Principal component analysis (PCA) enhances performance when using multiple principal components .
- Hyperspectral imaging (HSI) and near-infrared spectroscopy (NIR) are effective for detecting and visualizing soil nutrient distribution, particularly for total nitrogen (TN) and soil organic matter (SOM) .
-
Feature Selection and Preprocessing:
- Techniques like uninformative variable elimination (UVE), successive projections algorithm (SPA), and competitive adaptive reweighted sampling (CARS) are useful for selecting relevant spectral bands, improving model accuracy .
- Multiplicative Scattering Correction (MSC) is effective in reducing image scattering noise in hyperspectral images.
