It has been used in different tasks, such as the stratification of different pathologies, prediction of the user actions and activities, or modeling the energy usage. Specifically, behavior prediction can be used to forecast the future evolution of the users and to identify those behaviors that deviate from the expected conduct. In this paper, we propose the use of embeddings to represent the user actions, and study and compare several behavior prediction approaches. We test multiple model (LSTM, CNNs, GCNs, and transformers) architectures to ascertain the best approach to using embeddings for behavior modeling and also evaluate multiple embedding retrofitting approaches. To do so, we use the Kasteren dataset for intelligent environments, which is one of the most widely used datasets in the areas of activity recognition and behavior modeling.}, language = {English}, number = {3}, journal = {Sensors}, author = {Almeida, Aitor and Bermejo, Unai and Bilbao Jayo, Aritz and Azkune, Gorka and Aguilera, Unai and Emaldi, Mikel and Dornaika, Fadi and Arganda-Carreras, Ignacio}, month = jan, year = {2022}, keywords = {AI for health, CNN, JCR3.576, LSTM, Q1, activity recognition, artificial intelligence, attention, behavior modelling, behaviour prediction, convolutional networks, embeddings, futuraal, geometric deep learning, graph neural networks, knowledge graphs, machine learning, recurrent neural networks, transformers}, pages = {701}, } ']

Their integration in Content and Learning Management Systems (CMSs or LMSs) has been an active research topic for years, supporting mainly ad hoc solutions. A notable exception has been the use of federation protocols -commonly used for sharing laboratories from one university to other-, for actually sharing laboratories from a remote laboratory system to a C/LMS. This approach opened new doors in the simplification of the process, since it did not require the remote laboratories to make any type of change. The focus of this contribution is to provide a solution to decrease the number of functionalities required for creating an integration by providing a software component that reuses them. As shown in the contribution, this component has been implemented and two remote laboratory management systems (which provide access to multiple remote laboratories) are already supported, and a third one is under development. In the C/LMS side, all the LMSs supporting IMS LTI are supported, and HTTP APIs are provided for being supported by other systems.

Integration of remote laboratories on Learning Management Systems (LMS) or Content Management Systems (CMS) have also been addressed in the past, enabling institutions to delegate the authentication or authorization of the experiments to the LMS/CMS. However, these integrations are usually achieved in an ad hoc way, integrating each particular laboratory to a LMS/CMS. This contribution studies the use of federation models to integrate remote laboratory management systems in LMS/CMSs, since both approaches (integrating a laboratory on an a external electronic learning tool, and integrating a laboratory on other laboratory) are essentially equivalent.
