Abstract: Similarity queries, giving a way to disease diagnosis based on similar patients, have wide applications in eHealthcare and are essentially demanded to be processed under fine-grained access policies due to the high sensitivity of healthcare data. One efficient and flexible way to implement such queries is to outsource healthcare data and the corresponding query services to a powerful cloud. Nevertheless, considering data privacy, healthcare data are usually outsourced in an encrypted form and required to be accessed in a privacy-preserving way. In the past years, many schemes have been proposed for privacy-preserving similarity queries. However, none of them is applicable to achieve data access control and access pattern privacy preservation. Aiming at this challenge, we propose an efficient and access pattern privacy-preserving similarity range query scheme with access control (named EPSim-AC). |

Title: Knowledge Base 4.0: Towards Intelligent Knowledge Bases in the Age of Big Data and Artificial Intelligence
Amin Beheshti Abstract: Intelligence is the ability to learn from experience. Knowledge workers in knowledge-intensive processes develop invaluable domain-specific expertise and knowledge over time. Accordingly, it is vital for organizations to capture this knowledge (which is hidden in the biological Neural Network of subject-matter experts) and enable novices/inexperienced knowledge workers to benefit from that in choosing the best next steps. This Keynote will highlight opportunities to link weak supervision and crowdsourcing techniques to incorporate knowledge in a continual fashion based on estimating uncertainty or errors from the existing knowledge and learning models. Applications may include handling cold start and concept drift situations. I will discuss the design of an intelligent Knowledge Base (KB), namely KB 4.0, for mimicking the knowledge of domain experts in knowledge-intensive processes, and using this knowledge to facilitate auto labelling of the data to be used in learning algorithms. I will present a few motivating scenarios and argue how inexperienced knowledge workers can benefit from such intelligent KBs.

Abstract for IKT2022 conference In this study, different stages of the life cycle of a typical electrical machine are reviewed and their corresponding Digital Twin is discussed. The requirements of an electrical machine are different at its life cycle from design and manufacturing stages up to operation and maintenance stages; therefore, one digital twin may not be suitable for all stages. The main focus of the study is on the operation and maintenance stages of an electrical machine, due to the fact that for an existing machine other stages of its life cycle have been already elapsed. Depending on the importance of a typical electrical machine, traditionally, it is equipped with a number of sensors and transducers in order to facilitate monitoring of its operating condition. The collected data, analogue or digital, is processed to display/record the desired parameters of the machine; and more importantly, to issue an alarm and/or a trip signal when certain parameters reach a pre-set level. The usual protection system of a typical electrical machine operates in a binary mode. By adopting a suitable digital twin of an electrical machine, the idea is to adjust and control the machine operational point to maintain its parameters within the safe limits and to avoid an unwanted trip. In other words, to perform a predictable and controlled trip, if a trip is unavoidable. Another important use of digital twin of an electrical machine is to achieve and manipulate a predictive maintenance schedule for certain parts of the electrical machine, compared with other methods of maintenance. Other feasible usages of a machine digital twin are left to the imagination of the engineering community employing modern technologies such as the Internet of Things and Artificial Intelligence. |

Title: Towards Personalized Education Through Contextual Content Enrichment
Vikram GoyalAbstract: Online learning platforms have changed the landscape of education. It has enabled the paradigm of learning from anywhere, imparting knowledge to the learners beyond the traditional classroom setting. To deliver learning content at scale to the learners and cater to the individual needs of the learners, the content in such platforms can no longer be static. It must adapt according to the interaction of the individual learners with the system. The learning platforms should allow onboarding of the new content from other sources and enrich existing content to fulfill the need of diverse learners. Our lab has worked on tasks related to content enrichment for enabling the search through various facets, difficulty estimation of questions, paraphrasing of algebraic word problems, and duplicate question detection. Solving the problems mentioned above would aid in designing better content for learning platforms and contribute toward the broad vision of personalized education. This talk would discuss various challenges and the solutions thereof related to the challenges. |

Abstract: In this talk, we highlight the research challenges in the intersection of Machine Learning and Edge Computing. More specifically, we look at the Federated Learning paradigm in a faulty edge ecosystem.
Federated Learning deviates from the norm of ”send data to model” to ”send model to data''. When used in an edge ecosystem, numerous heterogeneous edge devices collecting data through different means and connected through different network channels get involved in the training process. Failure of edge devices in such an ecosystem due to device fault or network issues is highly likely.
In this talk, we first analyse the impact of the number of edge devices on an FL model and provide a strategy to select an optimal number of devices that would contribute to the model. We observe the impact of data distribution on the number of optimal devices. We then investigate how the edge ecosystem behaves when the selected devices fail and provide a mitigation strategy to ensure a robust Federated Learning technique. Finally, we design a real-world application to highlight the impact of the designed mitigation strategy.
The talk will end with a brief discussion of several open research problems in the intersection of Machine Learning and Edge Computing.

Title: Towards the Development of a Realistic Multidimensional IoT Profiling Dataset
Hassan MahdikhaniAbstract: The Internet of Things (IoT) is an emerging technology that enables the development of low-cost and energy-efficient IoT devices across various solutions from smart cities to healthcare domains. With such a complex and heterogeneous instance of IoT devices and their applications, numerous challenges arise in both device management and security concerns. Thus, it is essential to develop intelligent IoT identification/profiling and intrusion detection components that are tailored to IoT applications. Such systems require a realistic and multidimensional reference IoT dataset for training and evaluation. Device identification/profiling ensures the authenticity of the devices attached to the IoT network and environment which can be achieved by fingerprinting a device. Since fingerprinting is mostly examined by device network flows and device local attributes, we have proposed this study to intelligently recognize machine-to-machine communication and identify each device properly. In this paper, we analyzed the behaviour of 60 IoT devices during experiments conducted in our lab setup at the Canadian Institute for Cybersecurity (CIC). Our IoT devices include WiFi, ZigBee, and Z-Wave devices. We collected data from each device in four stages: powered on, idle, active, and interactions. Besides these stages, different scenario experiments were conducted using a microcosm of devices to simulate the network activity of a smart home. Additionally, we have generated two attack datasets, namely flood denial-of-service attack and RTSP brute-force attack. Lastly, we implement an extensive case study on the transferability of the RF classifier and train our model with the dataset from our lab, transfer the model to the dataset from a different lab and test the trained model on their dataset. This paper’s dataset materials are available on the CIC dataset page under the CIC IoT dataset 2022. |

Title: Behavioural Monitoring and Security Profiling in the Internet of Things (IoT)
Sajjad DadkhahAbstract: In recent years the number of IoT devices in businesses has significantly increased, which creates an undeniable challenge for network administrators and industries to identify and monitor the heterogeneous IoT environment. Also, identifying IoT devices helps organizations resolve several security dilemmas, such as determining if connected IoT devices' behaviour is compromised or not. In this work, we propose a distributive profiling mode to distinguish between IoT and non-IoT devices, map devices, identify the network that devices are attached to, and then continuously update the profile. Using a hybrid set of features and 23 new proposed features for identifying IoT devices, our method improves accuracy and shorter training time compared to other existing methods. Our proposed approach experiments with 18 Machine Learning (ML) classifiers on three publicly available datasets, i.e., IoTSentinel, UNSW, LSIF. Our study shows that Random Forest (RF) and Decision Tree (DT) classifiers outperformed the other ML classifiers by achieving an average accuracy, precision, recall, and f1-score above 90% with a shorter training time. This shows that our proposed system is suitable for providing a more generalized solution for profiling IoT devices. |
