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 large amounts of data, combined with ML, offers companies an unprecedented level of decision-making and automation.

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

March 17, 2020 | by Miguel Román

Data scientists love anomaly detection as anomalous samples provide valuable insight that often correlates with defects or errors in the data collection process. This blog post demonstrates how we leverage neural networks to build a time-based anomaly detector, featured in SmartAnalytics, for mobile network testing use cases.
