Professor Carlos Juiz received his PhD degree in Informatics from the University of the Balearic Islands (UIB), Spain. He has a postgraduate degree in Office Automation Management from the Polytechnic University of Madrid, Spain. Before joining the Department of Computer Science at UIB, he held several positions in the computer systems industry. From 1990, he was a Systems Analyst in Xerox, leaving this position as a Senior Analyst in 1999. He was a visiting researcher at the Department of Computer Science and Business Informatics, University of Vienna, in 2003, and a Visiting Associate Professor at the Biomedical Informatics Research Center, Stanford University, in 2011. Carlos Juiz is heading the ACSIC research group (http://acsic.uib.es), and his research interest mainly focuses on performance engineering, Green IT, and IT governance. He has been involved in 50 regional, national, European, and international research projects, including cooperation projects mainly with the Universities of Paraguay, Colombia, Albania, Tunisia, Morocco, and Ecuador. He has participated in more than 600 international conferences, workshops, and congresses as a reviewer, session chair, president of the program committee, but mostly as a programme committee member or scientific committee member. He is a co-author of more than 250 international papers (including journals, published reviews, proceedings, and book chapters) and two university textbooks. Carlos Juiz has given about 50 international seminars and has been invited to conferences at numerous prestigious universities in the world. Carlos Juiz isa senior member of the IEEE and also a senior member of the ACM. He has also been appointed as a member of the Domain Committee on Cloud Computing from IFIP until 2017. He was the Sub-director of the Polytechnic School (2004-2005) and Director of the Office of Planning and Prospective at the University of the Balearic Islands (2005-2007). He was the President's Delegate of New Technologies (2007-2011) and Vice-rector for Information Technologies (2011-2013) at UIB. Carlos Juiz was the Director of the Chair of Telefónica at UIB (2012-2014). He is one executive vice-president at the TURISTEC cluster and also a board member of Balears.t cluster.

Energy Scalability in the Training of AI Models for Image Processing: The Role of Hyperparameters
Journal of Systems Scalability | Volume 1, Issue 1: 1-5, 2026 | DOI: 10.62762/JSS.2025.960646
Abstract
This perspective article argues that hyperparameters such as learning rate, batch size, numerical precision, and training workers are key determinants of energy scalability in CNN training. These parameters directly influence convergence dynamics, hardware utilization, and training duration, leading to substantially different energy profiles even when comparable accuracy is achieved. Moreover, hyperparameter search itself introduces a significant cumulative energy cost, often exceeding that of the final selected model. By analyzing the interaction between convergence behavior and energy consumption, this work highlights the need to treat energy as an explicit scalability metric and to integr... More >
