Roberto Pereira received his M.Sc. degree in Informatics from the Technical University of Munich (Germany) in 2019 and Bachelors degree in Computer Science in 2014 from the Federal University of Maranhão (Brazil). Due to his research in the field accessibility on handwritten musical content using deep learning, he was awarded with the “Young Researcher Reward” by FAPEMA in 2014. Since then he has conducted numerous researches and deployed models in the fields of deep learning, computer vision, electrical signals, NLP, dimensionality reduction and wireless communication.

Currently, Roberto Pereira is a Marie Sk?odowska-Curie fellow ESR working on a European Training Network (ETN) project called Windmill. The network consists of a consortium of leading international research institutes and companies with experts in wireless communications and machine learning. The project itself aims at developing new network management and optimization tools based on machine learning.

As an Early Stage Researcher, Roberto’s role in the Windmill project is to analyze and synthesize machine learning solutions in large dimensional settings. Thus, he is focused on dimensionality reduction methods, unsupervised learning algorithms, smart agents and large optimization scenarios.
