Intelligent vulnerability assessment system for college students mental health based on few-sample reinforcement learning approach

Introduction

College students' psychological vulnerability assessment is constrained by data scarcity, high labeling cost, privacy sensitivity, and small, imbalanced samples, and existing frameworks typically treat vulnerability as a static judgment that cannot track how a student's condition changes over time. This study examined whether a few-sample hierarchical grading model combined with meta-reinforcement-learning-based sequential decision-making could address both problems jointly.
