Title: “Recommending POIs in LBSNs with Deep Learning”
Abstract:

In recent years, the representation of real-life problems into k-partite graphs introduced a new era in Machine Learning. The combination of virtual and physical layers through Location-Based Social Networks (LBSNs) offered a different meaning to the constructed graphs. To this point, multiple diverse models have been introduced in the literature that aims to support users with personalized recommendations. These approaches represent the mathematical models that aim to understand users’ behavior by detecting patterns in users’ check-ins, reviews, ratings, and friendships. In this talk, we discuss state-of-the-art methods for POI recommendations based on deep learning techniques. First, we categorize these methods based on data factors or features they use, the data representation, the methodologies applied, and the recommendation types they support. By briefly representing recent key approaches, we highlight the limitations and trends. The future of the area is illustrated.

Title: “Cloud Sustainability via ML-based Microservice Resource Management”
Abstract:

The growing adoption of MicroService Architectures (MSA) has led to a number of research efforts to improve their performance, reliability, and robustness via demand-driven scaling, ensuring Quality-of-Service and the enforcement of Service-Level agreements (SLAs). However, less attention has been devoted to efficient cloud resource allocation and optimal power management, which are crucial for the sustainability of data-driven, computation-intensive applications. In this talk, we survey some microservice frameworks, highlighting the problems of controlling resource utilization and power consumption. We discuss the assumptions behind the growing use of Machine Learning as an alternative to, or in association with, traditional optimization techniques for optimizing workload-driven resource sharing within microservice meshes.

Title: “Privacy and Cybersecurity in the Age of IoT”
Abstract:

Fast-paced technological developments have created a proliferating web of interconnected smart devices that exchange a large volume of data on a daily basis. In today’s world, an average person is estimated to have four IoT devices including smartwatches, phones, personal assistants, etc. Users have grown accustomed to the services offered by such devices that they often overlook how much of their private information is known to other companies and third parties. This data includes medical details captured by insulin pumps and pacemakers as well as virtual assistants that know a person’s schedule, activities, sleeping habits, intimate relationships, and so much more. The benefits of IoT devices are well recognized but users can be remiss about the potential harm this technology can pose. The lack of awareness amongst the general public is usually demonstrated in the way they handle their devices such as constantly leaving their location tracker on. In this talk, I will highlight the urgent need for privacy-preserving measures on three fronts: the technical, regulatory, and human sides. First, the devices themselves need to have secure communication protocols and deploy adequate risk management assessments and interventions. Second, tighter restrictions have to be considered: The current lack of specific regulations leaves a backdoor open for suspicious activities that can escalate to highly unethical practices like harvesting data belonging to minors. Third, the user should be aware of what information they are sharing, with whom, and for how long would that data be retained.
