Digital Twin Technology Development and Demonstration for Aircraft Structural Life-Cycle Management

Talk Summary:

This presentation will present the Airframe Digital Twin (ADT) framework and key technologies for aircraft structural life-cycle management, developed by the National Research Council of Canada (NRC), with the aim of significantly reducing maintenance cost and extending the remaining useful life of aircraft components. The NRC ADT technologies include high-fidelity structural modelling, probabilistic usage/loads forecasting, probabilistic crack growth modelling, Bayesian updating based on non-destructive inspection (NDI) results, and advanced risk/reliability analysis. To demonstrate the NRC ADT framework, a full scale fatigue test was used as a physical platform to simulate the remaining lifespan of an aircraft component.

Investigating the Capabilities of Large Language Models in Financial and Legal Analytics Tasks

Talk Summary:

Large language models (LLMs), such as ChatGPT and Llama-2, have achieved state-of-the-art performance in many natural language processing (NLP) and related tasks. In this talk, I will discuss our recent investigation of LLMs’ capabilities and limitations in several typical financial and legal tasks. For the financial applications, we explored areas such as the Chartered Financial Analyst (CFA) examination, sentiment analysis, and financial question answering, while in the legal domain, we focused on legal citation analysis. Through detailed experiments, we will demonstrate that, although current LLMs have achieved impressive performance, they still face significant limitations in these tasks.

Cryptologic History & Canada

Talk Summary:

This presentation will shed light on a number of the most meaningful instances involving cryptologic history and Canada through a selection of events, its people and artifacts. Although a good number will be concentrated in World War 2 and the Cold War, instances from the 18^th and 19^th centuries will also be shared. As one example, what role, if any, did Canada play in the breaking of Enigma in World War 2? There will also be a cursory glance at where cryptologic artifacts can be found in present day Canada.

Speaker info:

Richard Brisson is a graduate from the University of Ottawa (BSc Math-Physics in 1978 and MSc Systems Science in 1980). Upon graduation, he was hired by Canada’s Communications Security Establishment (CSE) from which he retired in 2011. His career at CSE largely encompassed various fields of Mathematics and Computer Science — he is also a graduate of NSA’s three-year Cryptologic Mathematics Program (1984-1987).

Although most of his papers are of a classified nature, Brisson and his colleague François Théberge co-published an unclassified pamphlet titled “An Overview of the History of Cryptology” in the early 2000s.

Over the last 30 years, Brisson has been collecting vintage cryptographic and clandestine artifacts dating up to and including the Cold War. Key World War II artifacts in the collection include a three-rotor Wehrmacht Enigma, a four-rotor Kriegsmarine Enigma and a commercial K-Enigma, which were manufactured in Germany and sold to Switzerland.

He has given numerous talks on Enigma at various institutions and conferences including the University of Calgary, University of Waterloo, Carleton University, University of Ottawa, Cryptologic Symposium in Charlotte SC USA, Canadian Association for Security and Intelligence Studies in Kingston, etc.

Brisson has had a passion for understanding how vintage cryptographic systems function at the algorithmic level, understanding their strengths and weaknesses, developing software simulators and also writing applications that attempt to exploit/break some of these vintage systems including the German WW2 Enigma. 

Through the years, he has had a number of partnerships with various museums in the display of artifacts including the Diefenbunker (Cold War Bunker in Carp near Ottawa), National Museum of Science and Technology (in Ottawa), the National Cryptologic Museum (Fort Meade, Maryland USA), and the Canada Aviation and Space Museum in Ottawa with a forthcoming spring 2024 Cold War exhibit. Portions of his collection can be viewed at the ultrasecret.ca website.

Big data analytics and artificial intelligence in cancer research and precision medicine.

Talk Summary:

Big data analytics and artificial intelligence (AI) has grown exponentially over the past decade in oncology and precision medicine. The increased data volume and capacity for data aggregation and analytics power, along with decreasing costs of genome sequencing has spurred the growth in bioinformatics and need for novel tools to extract meaningful patterns imbedded in these data from multiple sources and of varying types. The big data and AI tools have already created significant impact in many fields of medicine. However, the data complexity and multi-dimensionality in medicine has led to technical challenges in developing and validating AI solutions that generalize to diverse populations and imped the progress in their implementation in clinical practice due to imbalance in data distribution across population demography and data sparsity. This leads to the unconscious biases in the generated models and algorithms. In this talk, the speaker will discuss major applications of AI in cancer research and precision medicine, major challenges in implementation of AI in the clinical applications.

Be Ready for AI Third Wave!?

Talk Summary:

We have witnessed the achievements of AI research and its impact on human life and society over the past few decades. Since its inception at the Dartmouth Conference 1956, AI has gone through several boom and bust cycles.  Each bust pushed AI research from one boom to yet another prosperous boom. For example, the most recent bust from 1987 to 1993 led to another AI research boom which has lasted almost 20 years (2000-2019).  During the last two decades, many dreams in AI research have become reality. However, today AI development run into many barriers in meeting the expectations of public in the commercialization AI technologies such as safe-driving, self-abstracting, self-learning, etc. In this talk the speaker will explore where is boundary to impede the AI advancement by reviewing the AI history, and the major achievements from the first and second AI waves. Then speaker will share the vision of next AI wave in order to be ready for AI third wave. We believe in that the AI third wave is coming and will be a much stronger torrent！

Bounding treatment effects with deep generative models

Talk Summary:

In this talk, I’ll focus on the problem of partial identification, the estimation of bounds on the treatment effects from observational data. Although studied using discrete treatment variables or in specific causal graphs, partial identification has been recently explored using tools from deep generative modeling. I’ll describe a new method for partial identification of average treatment effects (ATEs) in general causal graphs using implicit generative models comprising continuous and discrete random variables. Since ATE with continuous treatment is generally non-regular, we leverage the partial derivatives of response functions to define a regular approximation of ATE, a quantity we call uniform average treatment derivative (UATD). The resulting algorithm converges to tight bounds on ATE in linear structural causal models (SCMs). For nonlinear SCMs, empirically, that using UATD leads to tighter and more stable bounds than methods that directly optimize the ATE. This is joint work with Vahid Belazadeh and Vasilis Syrgkanis.

Action-Based Networks: A Robust Framework for Synthesizing Complex Networks using Multiple Connection Mechanisms

Talk Summary:

Social contact, biological interactions, brain structure/function, and IT infrastructure are examples of real-world systems that can be modeled as complex networks, which are ill-defined mathematical objects that exist as a subset of all graphs. These networks have non-trivial topological properties that typically occur when the network is a model of a real-world system, and analysis of the network or its model can reveal new scientific and practical insights into the system.
