CS Colloquium - Nathan Sturtevant (University of Alberta / Amii) - Researching the foundations of heuristic search
Wed, Feb 07, 2024 @ 09:00 AM - 10:00 AM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Nathan Sturtevant, University of Alberta / Amii
Talk Title: Researching the foundations of heuristic search
Abstract: Although the field of heuristic search is over 50 years old, the last 6-7 years have seen numerous revisions to the foundational algorithms in the field. These include the theories for bidirectional search, for suboptimal search, and for improving the worst-case performance of fundamental algorithms such as A* and IDA*. This talk will give an overview of these new results, demonstrating the changes and their impact, many of which center around the notion of whether re-expansions are allowed during search.
This lecture satisfies requirements for CSCI 591: Research Colloquium.
Biography: Nathan is a Fellow and Canada CIFAR AI Chair at Amii and a Professor in the Department of Computing Science at the University of Alberta. His research looks broadly at heuristic and combinatorial search problems, including both theoretical and applied approaches, with many applications in games. His work on pathfinding was used in the game Dragon Age: Origins, and will appear in the upcoming Nightingale. Nathan’s work has won the best paper awards at the AAAI, and SoCS conferences, as well as the AI Journal Prominent Paper Award.

Talk Title: Bone Bioengineering: Microstructure, Mechanics, Mechanobiology, and Beyond
Abstract: Bone bioengineering is a basic science of clinical significance in many medical fields, such as osteoporosis, osteoarthritis, or intervertebral disc degeneration. I will highlight our development of three-dimensional imaging analysis and modeling techniques for trabecular bone microstructure, its applications in basic science research of bone mechanics, and clinical applications in osteoporosis and osteoarthritis. We will discuss bone microstructural phenotypes in different races and their implications in genetic and precision medicine, anthropology, evolution, and mechanobiology of the skeletons. In parallel to these developments, we will also showcase how mechanobiology links to bone microstructure and mechanics

Title: A Function Approximation View of Database Operations for Efficient, Accurate, Privacy-Preserving & Robust Query Answering with Theoretical Guarantees
Abstract: Machine learning models have been recently used to replace various database components (e.g., index, cardinality estimator) and provide substantial performance enhancements over their non-learned alternatives. Such approaches take a function approximation view of the database operations. They consider the database operation as a function that can be approximated (e.g., an index is a function that maps items to their location in a sorted array) and learn a model to approximate the operation's output. In this thesis, we first develop the Neural Database (NeuroDB) framework which extends this function approximation view by considering the entire database system as a function that can be approximated. We show, utilizing this framework, that training neural networks that take queries as input and are trained to output query answer estimates provide substantial performance benefits in various important database problems including approximate query processing, privacy-preserving query answering, and query answering on incomplete datasets. Moreover, we present the first theoretical study of this function approximation view of database operations, providing the first-ever theoretical analysis of various learned database operations. Our analysis provides theoretical guarantees on the performance of the learned models, showing why and when they perform well. Furthermore, we theoretically study the model size requirements, showing how model size needs to change as the dataset changes to ensure a desired accuracy level. Our results enhance our understanding of learned database operations and provide the much-needed theoretical guarantees on their performance for robust practical deployment.

Talk Title: Microfluidics with Macro-Impact: Advancing Sustainability through Nanoparticle - Enhanced Foams for Optimized CO2 Sequestration
Abstract: The contemporary global challenge centers on ensuring water and energy access for a growing population while minimizing environmental impacts and promoting sustainability. Porous media play a crucial role in this, facilitating processes like carbon sequestration, hydrogen storage, and geothermal energy extraction within geological formations. The Paris Climate Accord emphasizes reducing greenhouse gas emissions, with carbon sequestration in geological formations being a potential solution. However, challenges like ensuring safe storage and preventing leaks remain. Utilizing a foaming solution alongside CO2 injection emerges as a promising method to reduce the mobility of CO2, enhancing the blockage of CO2 in more permeable areas and thus bolstering storage safety. A significant hurdle in this technique is the thermodynamic instability of the bubble interface in the high salinity brines found in host formations. The introduction of nanoparticles enhances the interface's stability, counteracting the capillary forces that destabilize the foam's lamellae. The dynamics of gas-liquid interfaces differ between aqueous surfactants and nanoparticles. Nanoparticles impact the drag on elongated bubbles at low capillary numbers by establishing monolayer formations at the fluid interface, which in turn increases the interfacial dilatational viscoelasticity. This enhancement in viscoelasticity strengthens the interface's dynamic resistance to changes in surface area, whether through stretching or compressing, thereby improving the stability of the interface.
