Modeling of diatom indices (Bdı, Tdı and Gdı) based on the physico-chemical structure of the river ecosystem with machine learning and artificial intelligence methods; a comparative example
Diatom indices are used to assess the quality of aquatic plants in sustainable river ecosystems. The traditional assessment of diatom indices involves complicated and lengthy process steps. Today, artificial intelligence-based modelling plays a key role in overcoming this complexity. The aim of this work is to model selected diatom indices Biological Diatom Index (BDI), Trophic Diatom Index (TDI) and General Diatom Index (GDI) based on the physicochemical structure of river ecosystems using artificial intelligence and machine learning methods. The application part of the study used surface water variables from rivers monitored by 5 different stations for 24 months as a data set. Traditional analyses were compared with artificial intelligence and machine learning methods using the MATLAB programme. Different algorithms were considered, including Neural Network/Multilayer Perceptron (MLP), Support Vector Machine (SVM), Linear Regression (LR), Gaussian Process Regression (GPR), Decision Tree and Levenberg-Marquardt (LM) approach. To evaluate the quality of the models, the coefficient of determination (R2), root mean square error squared (RMSE) and mean absolute percentage error (MAPE) were compared. The R2 values of the Levenberg-Marquardt model, which gave the best prediction results for BDI, TDI and GDI, were found to be Validation; 0.7691, Training; 0.9620 Testing; 0.8613, Validation 0.9273, Training; 0.9303, Testing; 0.9199, Validation; 0.9273, Training; 0.9303, Testing; 0.9199, respectively. Levenberg Marquardt efficiently predicted Diatom index results accurately with high precision. Our results show that artificial intelligence and machine learning methods are highly efficient tools for the prediction of diatom indices. A time-efficient and labour-saving application in sustainable ecosystem management was successfully demonstrated.

Understanding Diatom Indices: BDI, TDI, and GDI
Diatom indices are biological indicators crucial for assessing water quality and ecological status in river ecosystems. The study focused on three key indices:
- Biological Diatom Index (BDI): A standardized method developed in France, based on 209 diatom taxa, to link index values with overall water quality according to species auto-ecology.
- Trophic Diatom Index (TDI): Calculated using 86 diatom taxa, reflecting tolerance to inorganic nutrients, primarily used for controlling and detecting eutrophication.
- Generic Diatom Index (GDI): Calculated based on the generic composition of diatom communities, also serving as an indicator of water quality.
Traditionally, calculating these indices involves complex and time-consuming laboratory analyses, which AI modeling aims to simplify and accelerate.
Comparative Model Performance for Diatom Index Prediction
The study rigorously compared the Levenberg-Marquardt (LM) algorithm against other popular machine learning models like SVM, Linear Regression, Gaussian Process Regression, Decision Tree, and Ensemble Learning. LM consistently outperformed these alternatives, demonstrating superior predictive accuracy for all diatom indices.
| Metric | LM-ANN (BDI Validation) | Linear Regression (BDI Validation) |
|---|---|---|
| R² (Coefficient of Determination) | 0.7691 | 0.07984 |
| RMSE (Root Mean Square Error) | 0.4129 | 0.39397 |
| MAPE (Mean Absolute Percentage Error) | 2.6894 | N/A (MAE: 0.34049) |
Transforming Sustainable Ecosystem Management
The successful demonstration of AI and machine learning for diatom index prediction offers significant benefits for sustainable ecosystem management. By providing accurate and rapid assessments of river health, these models support proactive decision-making and resource allocation.
Case Study: Enhanced River Ecosystem Monitoring
In the Harșit Stream, traditional diatom index assessments were lengthy and resource-intensive. Implementing an AI-driven Levenberg-Marquardt model for BDI, TDI, and GDI predictions allowed for:
- Rapid Assessment: Significantly reduced the time required for data analysis, enabling quicker responses to changes in water quality.
- Resource Optimization: Minimized the labor and laboratory costs associated with traditional methods, freeing up resources for other critical monitoring activities.
- Proactive Management: Provided high-precision predictions, facilitating early detection of pollution trends and enabling timely interventions to maintain aquatic plant health.
This approach effectively showcased a time-efficient and labour-saving application vital for modern sustainable ecosystem management.
