Miguel A. Román is our expert on big data and machine learning. He has spent his entire professional career developing software and is now working on his PhD in machine learning (ML) at the University of Alicante, Spain. When Miguel first recognized the potential of ML in tasks that any standard programming framework could not achieve, he felt as if he knew nothing about computing. Since then, he’s hooked, enjoying the challenge of incorporating the benefits of ML into mobile network testing solutions. For him, the possibility to store and process big amounts of data, combined with ML, offers companies an unprecedented level of decision-making and automation.

Machine learning: Time-based anomaly detection (part 3)

Anomaly detection is a much-appreciated tool by data scientists. It aims to find data samples that do not conform to the regular distribution of the dataset to which they belong. Finding anomalous samples, also known as distribution outliers, provides valuable insight that often correlates with defects or errors in the data collection process (e.g., faulty or misconfigured equipment). This blog…

Machine learning use case: Call Stability Score (part 2)

In our previous post about machine learning (ML), we introduced the topic of artificial intelligence (AI) and hinted at the typical deep learning pipeline that is needed to apply ML on data collected with mobile network testing solutions from Rohde & Schwarz. In this post, we will demonstrate how we can leverage ML to extract more value out of the…
