AI Modeling Approach
This paper explores various machine learning algorithms to predict airline passenger satisfaction, including GBDT, Decision tree, AdaBoost, XGBoost, Random forest, Extremerandom tree, CatBoost, and HistGBDT. A comprehensive approach was used, involving initial feature screening with random forest and stability selection, followed by ranking using LightGBM's importance metrics. Ultimately, 46 features were selected for their substantial effect on passenger satisfaction. The HistGBDT algorithm was specifically introduced for its potential in this domain.
Data Preparation & Feature Engineering
The study utilized a public dataset from Kaggle, comprising survey results from an American airline. The dataset includes nearly 130,000 records with 26 passenger characteristics. Initial processing involved removing the 'id' field as it has no correlation with satisfaction. Categorical features such as Gender, Customer Type, Type of Travel, Class, and Satisfaction were label encoded (e.g., Male: 1, Female: 0). Feature engineering techniques, including statistical value construction and feature crossing, were applied to generate a total of 24 features. Correlation analysis using heatmaps revealed significant interrelationships between passenger characteristics, journey attributes, and service items, guiding the model's understanding of complex dependencies.
Performance Assessment Framework
To rigorously assess the performance of the machine learning models, several key evaluation indicators for binary classification were employed. The Confusion Matrix formed the foundation, defining True Positives (TP), False Positives (FP), True Negatives (TN), and False Negatives (FN). From this, metrics such as Accuracy (overall correct predictions), Precision (proportion of correctly identified positive cases among all positive predictions), Recall (proportion of actual positive cases correctly identified), and the F1-score (harmonic mean of precision and recall) were calculated. Additionally, the ROC curve and its associated AUC value were used to evaluate the model's ability to distinguish between classes, with higher AUC values indicating better performance.
Comparative Model Performance
A comparative analysis of the eight machine learning algorithms revealed that all models, except for the Decision Tree, achieved an accuracy rate exceeding 95%. The HistGBDT algorithm demonstrated superior performance across multiple metrics, achieving the highest accuracy (0.962), precision (0.968), F1-score (0.952), and AUC value (0.958). While its recall rate (0.938) was slightly lower than CatBoost and Random Forest, HistGBDT’s overall balance of high accuracy and strong generalization ability makes it the preferred choice for passenger satisfaction prediction. This highlights HistGBDT's effectiveness in handling complex data distributions and its potential for providing precise service optimization strategies.
