Enhanced backpropagation neural network accuracy through an improved genetic algorithm for tourist flow prediction in an ecological village
This study introduces Adaptive Multi-population Genetic Algorithm Backpropagation (AMGA-BP), a novel neural network model designed to enhance tourist flow prediction in ecological villages. The model features a unique dual-layer ladder-structured chromosome for simultaneous optimization of network structure and weights. Experimental results show AMGA-BP achieves superior performance (MAPE of 5.32%, r² of 0.9869) compared to traditional BP (25.22% MAPE) and GA-BP (13.61% MAPE) models, and also outperforms LSTM (8.20% MAPE) and Random Forest (9.80% MAPE). It maintains robust accuracy during peak seasons (6.00% MAPE) and adverse weather conditions (5.50% MAPE), providing more reliable tools for sustainable tourism management in sensitive areas like Banliang Ancient Village.

Explore Key Concepts
The core of the AMGA-BP model lies in its dual-gradient structural chromosome design, allowing for simultaneous optimization of network topology and connection weights. This overcomes limitations of traditional BP networks in random weight initialization and structure determination.
The AMGA-BP model significantly outperforms traditional BP (25.22% MAPE) and GA-BP (13.61% MAPE) models, achieving a MAPE of 5.32% and an R² of 0.9869. It also surpasses LSTM (8.20% MAPE) and Random Forest (9.80% MAPE) in accuracy, demonstrating its superior predictive capability.
Key innovations include an adaptive crossover and mutation probability mechanism, which dynamically adjusts probabilities based on population fitness. This prevents premature convergence and maintains genetic diversity, enhancing global and local search accuracy.

Application in Banliang Ancient Village Scenic Area
The AMGA-BP model was validated in Banliang Ancient Village, Hunan Province, an ecological scenic spot. This area presents unique challenges like abrupt weather changes, fragile ecosystems, and irregular seasonal demands, making it an ideal testbed for the model's robustness. The model successfully captured nonlinear patterns and maintained accuracy during peak holiday periods and adverse weather conditions, significantly outperforming conventional methods. For example, during heavy rainfall, it achieved a 66.7% error reduction compared to GA-BP, crucial for sustainable tourism and effective resource management in weather-sensitive ecological areas.
