Narrative CV:

Decebal Mocanu is Assistant Professor in Artificial Intelligence and Machine Learning within the DMB group, Faculty of Electrical Engineering, Mathematics, and Computer Science at the University of Twente; and Guest Assistant Professor within the Data Mining group, Department of Mathematics and Computer Science at the Eindhoven University of Technology (TU/e). 

From September 2017 until February 2020, Decebal was Assistant Professor in Artificial Intelligence and Machine Learning within the Data Mining group, Department of Mathematics and Computer Science, TU/e and a member of TU/e Young Academy of Engineering. In 2017, he received his PhD in Artificial Intelligence and Network Science from TU/e. During his doctoral studies, Decebal undertook three research visits at the University of Pennsylvania (2014), Julius Maximilians University of Wurzburg (2015), and the University of Texas at Austin (2016).

Prior to this, in 2013, he obtained his MSc in Artificial Intelligence from Maastricht University. During his master studies, Decebal also worked as a part time software developer at We Focus BV in Maastricht. In the last year of his master studies, he also worked as an intern at Philips Research in Eindhoven, where he prepared his internship and master thesis projects. Decebal obtained his Licensed Engineer degree from University Politehnica of Bucharest. While in Bucharest, between 2001 and 2010, Decebal started MDC Artdesign SRL (a software house specialized in web development), worked as a computer laboratory assistant at the University Nicolae Titulescu, and as a software engineer at Namedrive LLC.



Decebal and his co-authors have laid the ground (connected papers) for sparse training in deep learning (training sparse artificial neural networks from scratch), while introducing both static and dynamic sparsity. Besides the expected computational benefits, sparse training achieves in many cases better generalisation than dense training.

  • Static sparsity in A topological insight into restricted Boltzmann machines, Machine Learning (2016), preprint https://arxiv.org/abs/1604.05978 (2016)
  • Dynamic sparsity in Scalable training of artificial neural networks with adaptive sparse connectivity inspired by network science, Nature Communications (2018), preprint https://arxiv.org/abs/1707.04780 (2017).


Decebal short-term research interest is to conceive scalable deep artificial neural network models and their corresponding learning algorithms using principles from network science, evolutionary computing, optimization and neuroscience. Such models shall have sparse and evolutionary connectivity, make use of previous knowledge, and have strong generalization capabilities to be able to learn, and to reason, using few examples in a continuous and adaptive manner.

Most science carried out throughout human evolution uses the traditional reductionism paradigm, which even if it is very successful, still has some limitations. Aristotle wrote in Metaphysics “The whole is more than the sum of its parts”. Inspired by this quote, in long term, Decebal would like to follow the alternative complex systems paradigm and study the synergy between artificial intelligence, neuroscience, and network science for the benefits of science and society.
