Sustainable Food Systems: A Novel Hybrid Model for Agricultural Commodity Price Prediction

Researchers at Hebei Agricultural University have made a groundbreaking discovery in the field of sustainable food systems, developing a novel hybrid model to predict agricultural commodity market prices. The study, published in Frontiers in Sustainable Food Systems, proposes a sustainable hybrid model SV-PSO-BiLSTM, which integrates Seasonal-Trend decomposition procedure based on Loess (STL), Variational Mode Decomposition (VMD), Particle Swarm Optimization (PSO), and Bidirectional Long Short-Term Memory (BiLSTM) neural networks. This innovative approach first performs seasonal decomposition of the original data using the STL method, then applies the VMD method for double decomposition of the residual components, reconstructs the data based on sample entropy, and finally predicts agricultural commodity market prices using the BiLSTM network model optimized by the PSO algorithm.

Key Takeaways:

  • The SV-PSO-BiLSTM hybrid model achieves average values of 0.2241 for root mean square error (RMSE), 0.1665 for mean absolute error (MAE), 0.0207 for mean absolute percentage error (MAPE), and 0.9851 for the coefficient of determination (R2), surpassing those of other comparative models.
  • The research findings provide effective guidance for the reasonable regulation of agricultural commodity market prices and promote the healthy and sustainable development of the agricultural commodity industry.
  • The proposed model involves the integration of four different methods: Seasonal-Trend decomposition procedure based on Loess (STL), Variational Mode Decomposition (VMD), Particle Swarm Optimization (PSO), and Bidirectional Long Short-Term Memory (BiLSTM) neural networks.
  • The model was tested on four agricultural commodities (chili, garlic, ginger, and pork) and one agricultural financial derivative (soybean futures) and achieved significant improvement in predicted accuracy.
  • The authors of the study include Lihua Zhang, Fushun Wang, Kejian Wang, Zhenxue He, Chen Chen, Jiahao Liu, Chao Wang, and Zhe Wang.

Statistics:

  • The average RMSE of the proposed model is 0.2241, indicating a strong generalization ability.
  • The average MAE of the proposed model is 0.1665, indicating a high degree of accuracy.
  • The average MAPE of the proposed model is 0.0207, indicating a low degree of error.
  • The average R2 of the proposed model is 0.9851, indicating a strong explanatory power.
