Traditionally, each educational entity (institution, university, faculty, department, etc.) creates and uses its own prediction model starting from its own data. However, that approach is not always feasible or advisable and may depend on the availability of data, local infrastructure, and resources. In those cases, there are various machine learning approaches for sharing data and/or models between educational entities, using a classical centralized machine learning approach or other more advanced approaches such as transfer learning or federated learning. In this paper, we used data from three different LMS Moodle servers representing homogeneous different-sized educational entities. We tested the performance of the different machine learning approaches for the problem of predicting student dropout with multiple educational entities involved. We used a deep learning algorithm as a predictive classifier method. Our preliminary findings provide useful information on the benefits and drawbacks of each approach, as well as suggestions for enhancing performance when there are multiple institutions. In our case, repurposed transfer learning, stacked transfer learning, and centralized approaches produced similar or better results than the locally trained models for most of the entities.  \nKeywords: dropout prediction; predictive analytics; transfer learning; federated learning  \n1. Introduction  \nOne important task in learning analytics (LA) [1] and educational data mining (EDM) [2] research is student dropout prediction (SDP) . SDP is an important educational problem because of the high dropout rate, mainly from e-learning environments. The recent spread of online courses—with enormous numbers of enrolled students, only a fraction of whom complete their studies successfully—has led to increased attention to this problem. As a consequence, there is a growing interest in the adoption of automated systems for predicting student dropout. Automated methodologies have also caught the attention of researchers, particularly in the area of machine learning. Students doing online degree programs have a higher chance of dropping out than those attending conventional classroom environments. According to [3], 40–80% of online students drop out from online classes. Moreover, students may leave courses at any time without notice or further repercussions. Therefore, it is of paramount interest to find more effective methods of addressing the problem of dropout in e-learning environments. The specific objective of SDP in e-learning environments is to model student behavior interacting with e-learnin","cbCaioWLSWRxCYba","https://ap.wps.com/l/cbCaioWLSWRxCYba","pdf",5006053,1,21,"English","en",105,"# Introduction\n## Student dropout prediction in learning analytics and EDM\n## Binary classification framing and algorithms\n# Methods and Approaches\n## Centralized learning\n## Transfer learning strategies\n## Federated learning\n# Experimental Setup and Evaluation\n## Data from multiple Moodle entities\n## Deep learning-based classifier\n# Results and Discussion\n## Performance comparison across entities\n## Benefits, drawbacks, and recommendations","[{\"question\":\"Why is dropout prediction important in online education?\",\"answer\":\"High dropout rates in e-learning environments make early, automated prediction crucial.
