AI-Based Personalized Learning Analytics for Higher Education Systems

Artificial Intelligence (AI) has revolutionized the field of education by facilitating smart, personalized and adaptive learning experiences. The traditional higher education system tends to use a single approach to teaching which is unsuitable for the wide range of learning styles, abilities and attainment of individual learners. Personalized Learning Analytics (PLA) leverages AI to deliver tailored learning experiences, proactive interventions, and data-informed instructional choices, which enhance student learning outcomes. This study offers a comprehensive review and conceptual model on implementing AI-based personalized learning analytics in the higher education context. The framework is designed to leverage these diverse educational data sources, such as Learning Management Systems (LMS), assessment systems, attendance records, behavioral data, and patterns of student interactions, to create predictive models that pinpoint students who are at risk, suggest individualized learning resources, and tailor instructional approaches. The way explainable AI techniques are integrated further increases transparency, trustworthiness, and interpretability of learning recommendations for educators and students. Moreover, the framework highlights the ethical use of AI, such as handling privacy-sensitive data and ensuring responsible learning analytics. The proposed design seeks to boost student performance, student engagement, college retention rates, and institutional planning and decision-making, while also lowering drop-out rates. The paper covers recent advancements, technological underpinnings, research challenges, and prospects for AI-driven personalized learning analytics that could transform higher education into an intelligent, adaptive, and student-centric environment that meets the changing needs of digital learning and Industry 5.0.

Self-Supervised Learning Models for Autonomous Robotic Navigation

Autonomous robotic navigation has become a key capability for intelligent robots operating in dynamic environments such as warehouses, hospitals, smart cities, agriculture, and autonomous transportation. While supervised learning methods achieve strong navigation performance, they depend on large labeled datasets that are costly and time-consuming to obtain. Self-Supervised Learning (SSL) addresses this limitation by enabling robots to learn robust visual and spatial representations directly from unlabeled sensor data through self-generated learning objectives. This paper reviews recent advances in SSL techniques, including representation learning, contrastive learning, predictive learning, masked image modeling, and multimodal sensor fusion for autonomous navigation. It also examines the integration of data from RGB cameras, LiDAR, IMUs, GPS, depth sensors, and odometry to improve perception, localization, obstacle avoidance, and path planning in unknown environments. Finally, the paper discusses key challenges such as domain adaptation, computational efficiency, safety, and continual learning, highlighting SSL's potential to enable scalable, adaptive, and lifelong autonomous robotic navigation.
