Seminar Series 2023/2024
Speaker:
Professor WEI Lan
Associate Professor
University of Waterloo
Abstract:
Given its high mobility, high breakdown voltage and decent thermal conductivity, GaN technologies have shown great promise for high-power high-frequency (HP-HF), rapidly rising as a front runner for mm-wave to THz analog/RF circuits for IoT and 5G/6G wireless communication. Meanwhile, it is also heavily explored for power electronic applications for fast charging, data center, and electric vehicles. As GaN technology continues to improve, challenges of high design cost and sub-optimal system performance emerge as bottlenecks preventing the technology from wide scale deployment. Accurate, scalable and efficient compact model is key to overcome such challenges.
This presentation will provide a brief overview of the family of MVSG GaN compact model, including models for GaN HEMT, GaN multi-channel diodes and GaN transmission-line resistors. The model formulation and various features will be introduced. Application examples will also be demonstrated, showing the potentials of this group of physics-based compact models.
Biography:
Prof. Lan Wei received her B.S. in Microelectronics from Peking University, China (2001), M.S and Ph. D. in Electrical Engineering from Stanford University, USA (2007 and 2010, respectively). She is currently an Associate Professor at the University of Waterloo, Canada. She has intensive experience in device physics-based compact modeling including silicon and GaN technologies, device-circuit interactive design and optimization, integrated nanoelectronic systems with low-dimensional materials, cryogenic CMOS device modeling and circuit design for quantum computing. She has authored/co-authored more than 90 peered reviewed publications and served on the technical program committees including IEDM, ICCAD, DATE, ISQED, BCICTS, etc.

Decision trees in a formal world: machine learning (with constraints), controller verification, and unsatisfiability proofs for graph problems
Location
Room 801, 8/F, Ho Sin-Hang Engineering Building, CUHK
Category
Seminar Series 2023/2024
Speaker:
Assistant professor
Abstract:
Decision trees are an effective and concise way of conveying information, easily understood by virtually everyone regardless of the topic. Given the recent interest in explainable AI and related fields, decision trees stand out as a popular choice. From the algorithmic side, the unique structure of decision trees is interesting since it may be exploited to obtain much more efficient algorithms than structure-oblivious approaches.
In this talk, I will give an overview of the research we have been doing on leveraging the decision tree structure from three disjoint angles: 1) machine learning with constraints, where the goal is construct the optimal regression/decision tree representing tabular data whilst potentially respecting different types of constraints such as fairness, 2) controller/policy verification, where the aim is to verify that a decision tree controller satisfies desired properties in continuous time, and 3) explaining the unsatisfiability of a combinatorial optimisation problem on a graph, by representing proofs of unsatisfiability as a tree using graph-specific concepts. We show that for each of these problems, exploiting the decision tree structure is important in obtain orders of magnitude runtime improvements and/or interpretability.
The talk summarises about half a dozen of our papers (AAAI’21/24, JMLR’22, NeurIPS’22/23, ICML’23/24) and is meant to be accessible to all backgrounds, with plenty of time for discussion!
Biography:
Emir Demirovic is an assistant professor at TU Delft (Netherlands). He leads the Constraint Solving (“ConSol”) research group, which advances combinatorial optimisation algorithms for a wide range of (real-world) problems, and co-directs the explainable AI in transportation lab (“XAIT”) as part of the Delft AI Labs. Prior to his appointment at TU Delft, Emir worked at the University of Melbourne, Vienna University of Technology, National Institute of Informatics (Tokyo), and at a production planning and scheduling company.
The focus point of Emir’s current work is solving techniques based on constraint programming, optimising decision trees, and explainable methods for combinatorial optimisation. He is also interested in industrial applications, robust/resilient optimisation, and the integration of optimisation and machine learning. He publishes in leading AI conferences (e.g., AAAI, NeurIPS) and specialised venues (e.g., CP, CPAIOR), attends scientific events such as Dagstuhl seminars, Lorentz workshops, and the Simons-Berkeley programme, and frequently organises incoming and outgoing visits, e.g., EPFL, ANITI/CNRS, CUHK, Monash University, TU Wien.

Speaker:
Professor ZHANG Qirun
Assistant Professor, School of Computer Science
Georgia Institute of Technology
Abstract:
SMT formulas are first-order formulas extended with various theories. SMT solvers are fundamental tools for many program analysis and software engineering problems. The effectiveness and scalability of SMT solvers influence the performance of the underlying client analyzers. The most popular approach to improving SMT solving is by developing new constraint-solving algorithms. In this talk, we will discuss a new perspective on improving SMT solving via compiler optimization. Our basic idea involves translating SMT formulas to LLVM IR and leveraging LLVM optimization passes to simplify the IR. Then, we translate the simplified IR back to SMT formulas. In addition, this strategy can be extended to enhance the solving of unbounded SMT theories by utilizing their bounded counterparts.

Abstract:
With advancements in deep learning and AI techniques, medical image segmentation has experienced rapid development over the past decade. Modern DL-based models, utilizing large labeled datasets, often produce impressive benchmark results. However, practical issues, such as reliability and trustworthiness, persist when these models are implemented in hospitals and medical facilities.
This talk addresses two related aspects of medical image segmentation for improving model deployment: model evaluation and test-time methods. First, we will discuss our recent work on deployment-centric model evaluation, evaluation of foundation models and related techniques. Next, we will cover a series of test-time methods that we have developed to improve video segmentation consistency, enhance the quality of medical image segmentation, and more recently, advance segmenting anything in medical images.
Finally, we will briefly highlight several other projects from my group and discuss directions in medical image segmentation research that we find promising and important.

MVSG-based Compact Models for GaN Devices
Location
Speaker:
Professor WEI Lan
Associate Professor
University of Waterloo
Abstract:
Given its high mobility, high breakdown voltage and decent thermal conductivity, GaN technologies have shown great promise for high-power high-frequency (HP-HF), rapidly rising as a front runner for mm-wave to THz analog/RF circuits for IoT and 5G/6G wireless communication. Meanwhile, it is also heavily explored for power electronic applications for fast charging, data center, and electric vehicles. As GaN technology continues to improve, challenges of high design cost and sub-optimal system performance emerge as bottlenecks preventing the technology from wide scale deployment. Accurate, scalable and efficient compact model is key to overcome such challenges.
This presentation will provide a brief overview of the family of MVSG GaN compact model, including models for GaN HEMT, GaN multi-channel diodes and GaN transmission-line resistors. The model formulation and various features will be introduced. Application examples will also be demonstrated, showing the potentials of this group of physics-based compact models.

Decision trees in a formal world: machine learning (with constraints), controller verification, and unsatisfiability proofs for graph problems
Location
Speaker:
Assistant professor
Abstract:
Decision trees are an effective and concise way of conveying information, easily understood by virtually everyone regardless of the topic. Given the recent interest in explainable AI and related fields, decision trees stand out as a popular choice. From the algorithmic side, the unique structure of decision trees is interesting since it may be exploited to obtain much more efficient algorithms than structure-oblivious approaches.
In this talk, I will give an overview of the research we have been doing on leveraging the decision tree structure from three disjoint angles: 1) machine learning with constraints, where the goal is construct the optimal regression/decision tree representing tabular data whilst potentially respecting different types of constraints such as fairness, 2) controller/policy verification, where the aim is to verify that a decision tree controller satisfies desired properties in continuous time, and 3) explaining the unsatisfiability of a combinatorial optimisation problem on a graph, by representing proofs of unsatisfiability as a tree using graph-specific concepts. We show that for each of these problems, exploiting the decision tree structure is important in obtain orders of magnitude runtime improvements and/or interpretability.
The talk summarises about half a dozen of our papers (AAAI’21/24, JMLR’22, NeurIPS’22/23, ICML’23/24) and is meant to be accessible to all backgrounds, with plenty of time for discussion!

Emir Demirovic is an assistant professor at TU Delft (Netherlands). He leads the Constraint Solving (“ConSol”) research group, which advances combinatorial optimisation algorithms for a wide range of (real-world) problems, and co-directs the explainable AI in transportation lab (“XAIT”) as part of the Delft AI Labs. Prior to his appointment at TU Delft, Emir worked at the University of Melbourne, Vienna University of Technology, National Institute of Informatics (Tokyo), and at a production planning and scheduling company.
The focus point of Emir’s current work is solving techniques based on constraint programming, optimising decision trees, and explainable methods for combinatorial optimisation. He is also interested in industrial applications, robust/resilient optimisation, and the integration of optimisation and machine learning. He publishes in leading AI conferences (e.g., AAAI, NeurIPS) and specialised venues (e.g., CP, CPAIOR), attends scientific events such as Dagstuhl seminars, Lorentz workshops, and the Simons-Berkeley programme, and frequently organises incoming and outgoing visits, e.g., EPFL, ANITI/CNRS, CUHK, Monash University, TU Wien.

Constraint Transformation for Faster SMT Solving
Location
Speaker:
Professor ZHANG Qirun
Assistant Professor, School of Computer Science
Georgia Institute of Technology
Abstract:
SMT formulas are first-order formulas extended with various theories. SMT solvers are fundamental tools for many program analysis and software engineering problems. The effectiveness and scalability of SMT solvers influence the performance of the underlying client analyzers. The most popular approach to improving SMT solving is by developing new constraint-solving algorithms. In this talk, we will discuss a new perspective on improving SMT solving via compiler optimization. Our basic idea involves translating SMT formulas to LLVM IR and leveraging LLVM optimization passes to simplify the IR. Then, we translate the simplified IR back to SMT formulas. In addition, this strategy can be extended to enhance the solving of unbounded SMT theories by utilizing their bounded counterparts.

Model Evaluation and Test-time Methods in Medical Image Segmentation
Location
Speaker:
Associate Professor, School of Computer Science and Engineering,
Nanjing University of Science and Technology
Abstract:
With advancements in deep learning and AI techniques, medical image segmentation has experienced rapid development over the past decade. Modern DL-based models, utilizing large labeled datasets, often produce impressive benchmark results. However, practical issues, such as reliability and trustworthiness, persist when these models are implemented in hospitals and medical facilities.
This talk addresses two related aspects of medical image segmentation for improving model deployment: model evaluation and test-time methods. First, we will discuss our recent work on deployment-centric model evaluation, evaluation of foundation models and related techniques. Next, we will cover a series of test-time methods that we have developed to improve video segmentation consistency, enhance the quality of medical image segmentation, and more recently, advance segmenting anything in medical images.
Finally, we will briefly highlight several other projects from my group and discuss directions in medical image segmentation research that we find promising and important.
