Federated Machine Learning

Federated Machine Learning Federated Learning (FL) is a collaboratively decentralized privacy-preserving technology to overcome the challenges of data storage and data sensibility [1]. The last few years have been strongly marked by artificial intelligence, machine learning, smart devices, and deep learning. As a result, two challenges arose in data science, impacting how data can be accessed and used. First, with the creation of the General Data Protection Regulation (GDPR) [2], the data became protected by the regulation. Institutions cannot store or share data without users’ authorization. Another challenge is that in the era of big data, a large volume of […]

Finding Anomalies in Large Scale Graphs

Finding Anomalies in Large Scale Graphs   Problem definition Given a large, who-calls-whom graph, how can we  nd anomalies and fraud? How can we explain the results of our algorithms? This is exactly the focus of this project. We distinguish two settings: static graphs (no timestamps), and time-evolving graphs (with timestamps for each phone). We further subdivide into two sub-cases each: supervised, and unsupervised. In the supervised case, we have the labels for some of the nodes (‘fraud’/’honest’), while in the unsupervised one, we have no labels at all. Major lessons For the supervised case, the natural assumption is that […]

A Data Management Architecture for AIDA

A Data Management Architecture for AIDA One of the major challenges in the evolution of the RAID platform during the AIDA project is the need to further distribute the platform components to achieve greater levels of scalability, by leveraging the increasing edge computing capacity made available by the IoT and the imminent large-scale deployment of 5G cellular technology.   The advent of 5G networks and growing adoption of Internet of Things (IoT) devices lead to more opportunities for data collection and processing with hybrid edge-cloud systems.   In this architecture, edge devices — placed near where the data is being […]

How can we protect the security and the privacy of the AIDA platform?

How can we protect the security and the privacy of the AIDA platform? The evolution of the RAID platform during the AIDA project brings many benefits, but also many security and privacy concerns to be considered. Thus, discovering and implementing measures that address these new risks, while not degrading performance, is of utmost importance. The main challenges are related to the transition to edge, pushing the computational power to the edges of the network, to the integration of 5G supporting multiple tenants and network slicing, and finally to the privacy of the data gathered and analyzed.   Given these changes […]

Fraud Risk Management

Fraud Risk Management 5G presents an opportunity for telecom operators to capture new revenue streams from industrial digitization. In cases such as network-as-a-service (NaaS), network exposure is becoming a reality through the transformation of core telecom network assets into digital assets. With 5G, the dynamic provisioning and scaling of network capacity and resources are available for the first time. The vision of managing the network-as-a-service in the same way as a developer might manage cloud resources on Azure, AWS, or Google Cloud is happening through a combination of scalable infrastructure and the next generation of digital business support systems (BSS).
