Enhancing healthcare with AI-in-the-loop
Sriraam Natarajan | University of Texas at Dallas
This talk will be held on Thursday, November 7th at 12:45 pm in Stanley Thomas 316. Sponsored in part by the Jurist Center for Artificial Intelligence and the Center for Community-Engaged AI.
Abstract: Historically, Artificial Intelligence has taken a symbolic route for representing and reasoning about objects at a higher-level or a statistical route for learning complex models from large data. To achieve true AI in complex domains such as healthcare, it is necessary to make these different paths meet and enable seamless human interaction. First, I will introduce learning from rich, structured, complex and noisy data. One of the key attractive properties of the learned models is that they use a rich representation for modeling the domain that potentially allows for seam-less human interaction. I will present the recent progress that allows for more reasonable human interaction where the human input is taken as “advice” and the learning algorithm combines this advice with data. I will present these algorithms in the context of several healthcare problems -- learning from electronic health records, clinical studies, and surveys -- and demonstrate the value of involving experts during learning.

Quantum Topology and ISA Collaborative Optimizations for Reduced Noise NISQ Circuits
Alex K. Jones | Syracuse University
This talk will be held on Thursday, November 21st at 12:45 pm in Stanley Thomas 316.
Abstract: The promise of quantum computation comes from the ability to entangle multiple qubits to solve complex computing problems. Current quantum computer offerings, such as the superconducting-based quantum machines offered by IBM and Google, are strongly entrenched in the Noisy Intermediate Scale Quantum (NISQ) class of machines. Unfortunately, the noise in these machines limits the size of quantum circuits that can be realized before noise channels overcome the work by the quantum circuit. By working collaboratively between the quantum device design, quantum architecture, and quantum transpilation flow, it is possible to significantly decrease circuit depth and increase the problem size that can be computed in NISQ machines. In this talk I will present our recent findings for topology and gate co-design using Transmon qubits with SNAIL couplers. I will discuss methods for reducing two-qubit gate pulse lengths to provide greater control over quantum computations while also addressing the overhead of one-qubit gates. Using a concept called parallel drive, I will show how one-qubit gates can sometimes be eliminated by driving two-qubit and one-qubit gates at the same time without creating substantial calibration problems. I will also discuss a new transpilation approach called MIRAGE that takes advantage of mirror gates to improve circuit depth in the case of restricted radix topologies and for better decomposition in high-radix topologies.

Closing the Gap between Quantum Algorithms and Machines with Hardware-Software Co-Design
Fred Chong | The University of Chicago
Abstract: Quantum computing is at an inflection point, where 433-qubit machines are deployed, and 1000-qubit machines are only a few years away. These machines have the potential to fundamentally change our concept of what is computable and demonstrate practical applications in areas such as quantum chemistry, optimization, and quantum simulation. Yet a significant resource gap remains between practical quantum algorithms and real machines. A promising approach to closing this gap is to design software that is aware of the key physical properties of emerging quantum technologies. I will illustrate this approach with some of our recent work that focuses on techniques that break traditional abstractions and inform hardware design, including compiling programs directly to analog control pulses, computing with ternary quantum bits, 2.5D architectures for surface codes, and exploiting long-distance communication and tolerating atom loss in neutral-atom machines.

The Evolution of Computer Hardware and Software for Data-centric Computing
Xiaodong Zhang | The Ohio State University
Abstract: As Moore's Law ended, and Dennard Scaling reached its physical limitations, we have entered a new computing era that is marked by the coexistence of various parallel and highly specialized hardware accelerators with general-purpose processors. Over many years of development, the CPU-centric ecosystem has evolved into a one-size-fits-all environment, accommodating a diverse range of applications. However, the efficiency in performance, computing power and energy consumption has been continuously declining, making the general-purpose computing ecosystem unsustainable for the growing demands of data-centric computing.
In this presentation, I will explore the constraints and obstacles inherent in our current computing ecosystem, driven by Moore's Law. I will also provide case studies to support the evolution of computer hardware and software for high-performance data processing, featuring advanced hardware components such as GPUs, RDMA, and other relevant technologies. All associated algorithms and software implementations are open source, with some having been integrated into production systems.

Blockchains and Related Technologies: Which Ideas are Likely to Endure?
Maurice Herlihy | Brown University
Abstract: Blockchains and distributed ledgers have become the focus of much recent attention. Like many innovations, this field emerged from outside mainstream computer science, although almost all the component ideas were already well-known. As a new area driven mostly by technological and financial innovations, it can be difficult to distinguish accomplishment from aspiration, and especially difficult to tell which ideas are of transient versus lasting interest. This talk surveys the theory and practice of blockchain-based distributed systems from the point of view of classical distributed computing, along with opinions about promising future research directions. This talk is intended for a general audience.

Outracing Champion Gran Turismo Drivers with Deep Reinforcement Learning
Peter Stone | University of Texas at Austin
This talk will be held on Friday, December 2nd, at 4:00 p.m. CST in Stanley Thomas Hall, Room 302. Zoom details will also be provided via the announcement listserv, or you may email dramil1@tulane.edu to request the corresponding link.
Abstract: Many potential applications of artificial intelligence involve making real-time decisions in physical systems while interacting with humans. Automobile racing represents an extreme example of these conditions; drivers must execute complex tactical manoeuvres to pass or block opponents while operating their vehicles at their traction limits. Racing simulations, such as the PlayStation game Gran Turismo, faithfully reproduce the non-linear control challenges of real race cars while also encapsulating the complex multi-agent interactions. Here we describe how we trained agents for Gran Turismo that can compete with the world's best e-sports drivers. We combine state-of-the-art, model-free, deep reinforcement learning algorithms with mixed-scenario training to learn an integrated control policy that combines exceptional speed with impressive tactics. In addition, we construct a reward function that enables the agent to be competitive while adhering to racing's important, but under-specified, sportsmanship rules. We demonstrate the capabilities of our agent, Gran Turismo Sophy, by winning a head-to-head competition against four of the world's best Gran Turismo drivers. By describing how we trained championship-level racers, we demonstrate the possibilities and challenges of using these techniques to control complex dynamical systems in domains where agents must respect imprecisely defined human norms.
