Talk Title: Are Distributed Ledger Technologies Ready for Smart Transportation Systems?
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: In this talk, I'll present a system architecture that exploits Distributed Ledger Technologies (DLTs) and related software technologies to promote the development of smart transportation systems. DLTs provide very interesting features, such as immutability, traceability and verifiability of data. Thus, the designed system architecture allows creating, storing and sharing data generated by vehicles and users through their sensors, while moving. However, some doubts on the scalability and responsiveness of these technologies appear to be well-founded. Experimental results of a real test-bed over IOTA, a promising DLT for IoT, will be discussed.

Talk Title: Control Synthesis Under Spatiotemporal Specifications
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Planning and control for multi-agent systems has been a popular topic of research, with applications in numerous real-world autonomous systems. Despite significant progress over the years, challenges such as constraints (in terms of state and time specifications), malicious or faulty information, environmental uncertainty and scalability are still open. In this talk, I will present some of our recent results and ongoing work on a Prescribed-Time Control Barrier Functions framework, where the barriers and underlying controllers meet state and time constraints. The framework builds upon the notions of finite-time and fixed-time stability, and redefines the standard control barrier functions to enable control synthesis that meets spatiotemporal specifications. The efficacy of the approach is illustrated via a spatiotemporal motion planning scenario.

Talk Title: Large-Scale Integrated Photonics for Accelerated Communication and Computing
Abstract: The massive explosion in data acquisition, processing, and archiving, hindered by the end of Moore's Law, creates an opportunity for a complete redesign of the information technology stack, including hardware system architectures,
devices, networks, and software to enable future computing systems with multi-exascale performance-”and beyond. Key
to success in this challenging endeavor will be the paradigm shift of moving from a processor-centric to a memory-centric
approach. Architectural changes are necessary to overcome the limitations of the traditional compute-centric model, and will
require new network layouts (e.g., Hyper-X) and new high-performance memory-addressing protocols (e.g., Gen-Z) that rely on a high-bandwidth and energy-efficient photonic interconnect. We will describe the state-of-the-art in datacom photonics and present the advances that will be necessary-”and are already appearing in R&D laboratories-”to enable memory-centric computing at scale.
Memory-centric computing would be an ideal heterogeneous platform for in-memory hardware accelerators that can be
brought to bear on specific problems of scientific, engineering, or industrial interest. Ideally, a mature software ecosystem would simplify the design of a plug-and-play network interface that would allow users to compare the performance of the most advanced accelerators. We will describe such an accelerator-”a coherent optical Ising machine-”that targets NP-hard problems that scale exponentially as a function of system size and are common to applications such as traffic flow optimization, supply chain management, airline scheduling, and DNA sequencing. Optical Ising machines based on symmetry-breaking in pulsed optical parametric oscillators have already been shown to outperform a commercially-available quantum annealer, and there is good reason to believe that integrated photonic implementations of this approach can achieve similar results.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Lin Tan, Purdue University
Talk Title: AI for Software and Software for AI
Abstract: This talk will present research focuses in two directions: (1) using software testing approaches to improve the dependability of machine learning systems, and (2) leveraging machine learning and natural language processing techniques to improve software dependability. Machine learning software is widely used in domains including aircraft collision avoidance systems, Alzheimers disease diagnosis, and autonomous driving cars. Despite the requirement for high reliability, machine learning software is difficult to test and debug. This talk will describe CRADLE, a new approach that (1) performs cross-implementation inconsistency checking to detect bugs in deep learning software, and (2) analyzes anomaly propagation to localize faulty functions in deep learning software. On the other hand, machine learning and natural language processing techniques have unique advantages in completing and automating challenging software development tasks. This talk will present techniques that automatically analyze software text, such as code comments, API documentation, and processor specifications, to extract specifications, generate test cases, and detect software bugs. In addition, this talk will discuss how to build machine learning models to produce specifications and bug patterns automatically from existing bugs and their commit messages to find new bugs.
