AIDA Webinar Series: Improving 5G Risk Management The AIDA project and the CMU Portugal Program are promoting a series of webinars on the improvement of 5G risk management. With this initiative, the project expects to launch a discussion that will contribute to highlight different topics and challenges related to this area. Starting in December 2021, this initiative will occur every two months between December 2021 and September 2022, gathering leading experts from academia to industry involved with the project. Each webinar will be hosted by two AIDA partners who will present and discuss their ideas on a specific topic. […]
Fraud detection, micro-clusters and scatterplots Acknowledgements The results and analysis presented here were done with contributions from Mirela Cazzolato (USP, and CMU), Saranya Vijayakumar (CMU), Xinyi (Carol) Zheng (CMU), Meng-Chieh (Jeremy) Lee (CMU), Namyong Park (CMU), Pedro Fidalgo (Mobileum), Bruno Lages (Mobileum), and Agma Traina (USP). Reminders – Problem definition and past insights As we mentioned in the February 2022 blog post, the problem we are focusing on is to spot fraudulent behavior in a who-calls-whom-and-when graph. We distinguished between the supervised case (where we are given a list of fraudulent subscribers (labeled data)), and the un-supervised one, where […]
The 1st Workshop on Secure and Reliable Edge Cloud Continuum (SREEC 22) The 1st Workshop on Secure and Reliable Edge Cloud Continuum (SREEC 22) will take place on October 31, 2022, in Charlotte, North Carolina, USA, and is co-located with the ISSRE 2022. The goal of this workshop is to bring together researchers and practitioners to discuss the current state of the art, emerging challenges and trends, as well as novel solutions, implementations and deployments of reliable hybrid edge-cloud systems and applications. The workshop is looking for submissions in the form of papers with no more than 6 pages describing novel contributions and […]
AIDA Project presented at the Carnegie Mellon’s Commencement Ceremony On May 13th, the AIDA project was presented at the CMU Portugal Program workshop that preceded the Commencement Ceremony, in Pittsburgh. Our researcher David Garlan, from CMU, presented the project as an ongoing research work, and collaboration between Portugal and CMU. David Garlan also talked about architecting effective ML based systems in the AIDA project and CMU Portugal Project Camelot. This event was an opportunity for CMU researchers and PhD students to address their ongoing research work in collaboration between Portugal and CMU.
AIDA paper presents a mechanism that ensures better performance and reduces costs in IoT devices “Adaptive Database Synchronization for an Online Analytical Cloud-to-Edge Continuum” is the new paper of the AIDA project, which was presented this week at the ACM Dependable, Adaptive, and Secure Distributed Systems (DADS 2022). Internet of Things devices are generally underpowered, but they exist in large volumes and are located very close to where the data is captured. The use of these devices is increasingly common in the industry, agriculture, running cities, and even at homes. Because of their limitations, the data is traditionally transferred periodically to […]
Federated Machine Learning Federated Learning (FL) is a collaboratively decentralized privacy-preserving technology to overcome the challenges of data storage and data sensibility . 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) , 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 […]
Consortium meeting gathers all partners On March 17, 2022, the AIDA consortium met in Braga (Portugal) to plan the last months of the project. The discussion focused on the use cases needed for pilot proposes and which frameworks can be used to execute the pilot correctly. Additionally, the partners discussed the tests required to achieve a good quality assurance metric. In this sense, collaboration between all partners is crucial in determining the success of project outcomes.
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 […]
AIDA project presented to MAP-i’s students Last week, close to 20 students from the MAP Doctoral Program in Computer Science (MAP-i) had the opportunity to get to know the AIDA project, focusing on cloud edge continuum. The MAP-i students – part of one of the PhD programs that is closely related to the research carried out within the scope of the project – also visited INESC TEC’s High-Assurance Software Laboratory, while learning how the AIDA project is a good example of the work done in the cloud edge continuum field, and as a model of international collaboration between industry and […]
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 […]
