Evolving fuzzy classification for human-centered explainable learning analytics in virtual environments
This study introduces Dynamic Incremental Semi-Supervised Fuzzy C-Means (DISSFCM) to analyze student interaction data from virtual learning platforms. It generates human-centered IF-THEN fuzzy rules from evolving prototypes, expressed in linguistic terms for non-expert stakeholders. Utilizing the Open University Learning Analytics Dataset (OULAD), the model adapts to concept drift, handles partially labeled data and variable time granularities, and provides intelligible explanations for student outcomes. Expert evaluation confirms the clarity, usefulness, and accuracy of the generated explanations, supporting its relevance for human-centered educational applications.
Executive Impact
By deploying DISSFCM, educational institutions can gain proactive insights into student performance and engagement, enabling early interventions and personalized support. The model's ability to handle partially labeled data and generate human-centered explanations in linguistic terms addresses critical challenges in real-world learning analytics, fostering trust and improving decision-making for educators and administrators.

F1 Score for 'Fail' class (monthly data), demonstrating robust identification of at-risk students.
A particularly noteworthy aspect of the study is the model's ability to maintain high performance even when the percentage of labeled data is drastically reduced.
The accuracy and F1 scores across the 100%, 75%, 50%, and 25% labeling scenarios are nearly indistinguishable, with differences falling well within the margin of variability.
This resilience underscores the strength of the semi-supervised, prototype-based framework, which enables the model to generalize from sparse labeled data and update its internal representations incrementally as new chunks are introduced.
