A Study on PI-KAN in the Pathways of Psychological Crisis Intervention for Vocational Students
This paper introduces PI-KAN, a Physics-Informed Kolmogorov-Arnold Network, for early psychological crisis detection in vocational students. It integrates psychological theories with data-driven learning using physics-informed constraints, Residual-Based Adaptive Sampling (RAD), and Residual-Based Attention (RBA). Experimental results show PI-KAN outperforms traditional models (MLP, LSTM, PINN) in RMSE reduction and crisis prediction precision (CPP), offering a clinically interpretable framework for proactive mental health monitoring and personalized intervention.

PI-KAN significantly outperforms traditional and physics-informed baselines across all evaluated metrics. It demonstrates a 20% reduction in RMSE and a 39% improvement in Crisis Prediction Precision (CPP) compared to standard models. The adaptive mechanisms (RAD, RBA) are crucial for optimizing performance in dynamic psychological state modeling, particularly in identifying early warning signs.
0.123
Lowest RMSE Achieved
PI-KAN recorded the lowest Root Mean Square Error (RMSE) at 0.123, indicating superior prediction accuracy for psychological states.
0.79
Highest Crisis Prediction Precision (CPP)
With a CPP of 0.79, PI-KAN excels in accurately identifying early warning signs of psychological crises.
Clinical Interpretability: Student Crisis Trajectory
A case study highlights PI-KAN's ability to identify a critical transition point where predicted stress levels sharply increase and coping capacity declines, corresponding to intensified academic workload. This allows for early intervention signals, such as temporary workload adjustments or enhanced social support, altering subsequent psychological trajectories. PI-KAN provides actionable insights, moving beyond opaque risk scores.
The study primarily relies on synthetic data, which simplifies real-world psychological dynamics and may not fully capture noise, heterogeneity, or non-stationary influences. Future validation with real-world longitudinal student data, spanning at least one academic semester, is essential to assess generalizability and temporal robustness across diverse cohorts and institutions. Ethical considerations, including IRB approval and de-identification, are paramount for real-world data collection.
