概要

The Canadian Institute for Cybersecurity (CIC) conducts research and development in various areas, including network security (such as intrusion detection and prevention, Dark Web, and malware analysis), systems security (covering mobile, software, and IoT), security analysis and risk management, security visualization, IoT-Big data security and privacy, critical infrastructure protection, and human-centric cybersecurity. Network-based IDSs require diverse datasets that represent a wide range of network behaviors and attack types. Finding and collecting representative data can be challenging, and datasets may be imbalanced, making it difficult to effectively train models. Generating synthetic network traffic data can help mitigate privacy and security concerns associated with real-world data. Dr. Ghorbani will discuss the datasets developed by his team at CIC over the past 15 years, which are used for training and testing cybersecurity solutions. The presentation will also include updates on CIC's latest R&D projects, project details, and research findings.

略歴

Dr. Ghorbani is the Tier 1 Canada Research Chair in Cybersecurity and founding director of the Canadian Institute for Cybersecurity he established in 2016. In addition, he served as the Dean of the Faculty of Computer Science at the University of New Brunswick from 2008 to 2017. He is the co-inventor of four awarded and one filed patent in Cybersecurity and Web Intelligence. He has published over three hundred peer-reviewed articles during his career. In addition, he has supervised over 250 research associates, postdoctoral fellows, and students. Dr. Ghorbani developed several technologies adopted by high-tech companies and co-founded three startups: Sentrant Security, EyesOver Technologies, and Cydarien Security, in 2013, 2015, and 2019. He co-founded the UNB-NRC Cybersecurity Collaboration Consortium and the National Cybersecurity Consortium (NCC) in 2019 and 2020, respectively. He co-founded the Privacy, Security, Trust (PST) Network in Canada and its annual international conference. Dr. Ghorbani served as the co-Editor-in-Chief of "Computational Intelligence: An International Journal" from 2007 to 2017. His achievements include receiving the 2017 Startup Canada Senior Entrepreneur Award, being named one of Canada's top 25 Canadian immigrants of 2019, and being recognized as one of the 40 inspiring Canadians in the book 'Forty Brilliant Canadians and Their Vision for the Nation' by Mark Bulgutch (2022). In addition, he received the 2024 Lifetime Achievement Award from CAIAC - the Canadian Artificial Intelligence Association.

概要

Machine learning research on graph-based structured data is booming, with thousands of papers released in the past years. The increased production does not only shows the interest in foundational research but the relevance in applications too, as graphs with their information entities and relational dependencies are everywhere. The seminar will open views on spatiotemporal neural graph processing, i.e., in research/application frameworks where, in addition to “space” relations we exploit those that emerge over the time dimension. Applications enabling such processing are e.g., those associated with sensor networks in domains nowadays named smart grids, smart cities, IoT, Industry 40. The focus will mostly be on the prediction and the imputation tasks within a deep relational processing.

The State of the Art of Collaborative Neurodynamic Optimization

概要

The past four decades witnessed the birth and growth of neurodynamic optimization, which has emerged as a potentially powerful problem-solving tool for constrained optimization due to its inherent nature of biological plausibility and parallel and distributed information processing. Despite the success, almost all existing neurodynamic approaches a few years ago worked well only for optimization problems with convex or generalized convex functions. Effective neurodynamic approaches to optimization problems with nonconvex functions and discrete variables are rarely available. In this talk, the advances in neurodynamic optimization will be presented. Specifically, In the proposed collaborative neurodynamic optimization framework, multiple neurodynamic optimization models with different initial states are employed for scattered searches. In addition, a meta-heuristic rule in swarm intelligence (such as PSO) is used to reposition neuronal searches upon their local convergence to escape local minima toward global optima. Problem formulations and experimental results will be elaborated to substantiate the viability and efficacy of several specific paradigms in this framework for supervised/semi-supervised feature selection, supervised learning, vehicle-task assignment, model predictive control, energy load dispatching, and financial portfolio selection.

開催報告

【講演概要】
香港城市大学のJun Wang教授に動的ニューラルネットによる協調型最適化手法の最新動向について、ご講演頂きました。まず、人の脳で行われている最適化の仕組みがフィードバック結合を有するニューラルネットの動的な特性を利用していることについて述べられ、そのパイオニアとしてJohn J. Hopfieldを紹介されました。そして、最適化問題の種類やその解法、特に非線形最適化問題を解くためのニューラルネットモデルと最適化問題への定式化、収束条件などを説明され、本講演の中心となるCollaborative Neurodynamicsの概念について詳細な説明がありました。
