Title: Artificial Intelligence:: Recent Developments and Futuristic Trends

Abstract: The quest for building human-like intelligence has gained enormous momentum in recent decades. Since the seminal works on Artificial Intelligence (AI), the desire of realizing the quest has become stronger. With the rapid developments in Science, Engineering and Technology, machines that mimic human intelligence have become a reality and sometimes indispensable parts in our daily life, such as Apple Siri and Google Voice. AI is the Science and Engineering that is concerned with the theory and practice of developing systems that exhibit the characteristics we associate with intelligence in human behavior: perception, natural language processing, reasoning, planning and problem solving, learning and adaptation, etc. In this talk, fundamentals and recent developments of AI techniques will be reviewed. The futuristic trends and challenges in AI will also be discussed.

Title: FPGA Based Acceleration for Big Data Processing: Challenges and Opportunities
With the rapidly rising demands of computing capability for big data processing, hardware accelerators are increasingly used in computing systems to satisfy the performance requirement. FPGAs are regarded as one of the promising hardware accelerators to implement various compute-intensive tasks due to their advantages of low power and massive parallelism. However, there are both challenges and opportunities faced by the community to employ FPGAs efficiently in such applications. In this talk, we will analyze the challenges and potential of using FPGAs for acceleration of big data processing applications including machine learning based processing in both the cloud and the edge devices. Particularly, although FPGAs can provide desirable
hardware solutions, it is not easy to implement and optimize FPGA based implementations, especially by designers who lack hardware background. We will present a series of design techniques and automation flows in high-level synthesis (HLS) to bridge this gap and facilitate the FPGA implementation with high performance and energy efficiency.

Title: Survival of the fittest: circuits and architectures with wide power-performance adaptation – Beyond voltage scaling and down to pWs
Wide power-performance adaptation is becoming crucial in always-on nearly real-time and energy-autonomous integrated systems that are subject to wide variability in the power availability and the performance target. Adaptation is indeed a prerequisite to assure continuous operation in spite of the widely fluctuating energy/power source (e.g., energy harvester), and to grant swift response upon the occurrence of events of interest (e.g., on-chip data analytics), while maintaining extremely low consumption in the common case. These requirements have led to the strong demand of a new breed of integrated systems having an extremely wide performance-power scalability and adaptation, beyond conventional voltage scaling or adaptive parallelism. In this context, systems being able to adapt to a wider performance-power range (“the fittest”) allow true continuous operation and adjustment to the power-performance profile required by the application (“survival”). In this talk, new techniques that drastically extend the performance-power scalability of digital circuits and architectures are presented. Silicon demonstrations of better-than-voltage-scaling adaptation to the workload are illustrated for both the data path (i.e., microarchitecture) and the clock path. Adaptation to a very wide range of energy/power availability is also discussed, presenting demonstrations of always-on systems (e.g., microcontrollers, power management units) with power down to sub-nW, and duty-cycled operation down to pW range. As an orthogonal design dimension, “just-enough” adaptation to the application-level quality requirement is shown to further extend the performance-power range by an order of magnitude or more. Under this energy-quality scaling framework, quality is treated as an explicit knob, eliminating the quality slack that is traditionally imposed by worst-case design across different applications (e.g., machine learning), contexts, datasets, and the pessimistic design margin to counteract process/voltage/temperature variations. Several silicon demonstrations are illustrated to quantify the benefits offered by wide power-performance adaptation, and identify opportunities and challenges for the decade ahead.

Title: “Embedded manycore programming: From auto-parallelization to domain specific languages”

Abstract:  Programming manycores remains a daunting task, especially in the presence of the heterogeneity and application constraints typical in the embedded domain.
This talk reviews efforts to cope with this complexity from the last 10+ years of research. It starts with the challenges faced by auto-parallelizing compilers, discussing how far they have made it since the start of the multi-core era. The talk also reviews explicit parallel programming and associated programming methodologies, with focus on recent advances that aim at increasing the adaptivity and robustness of dataflow applications. The talk then advocates for even higher-level programming abstractions in the form of domain specific languages, particularly important to deal with the increased complexity brought by emerging computing paradigms.

Title: “An On-Device Learning Approach for Unsupervised Anomaly Detection on Chip”

Abstract:  Toward on-device learning for edge and IoT devices, we will introduce a neural-network based online sequential learning and unsupervised anomaly detection (OSL-UAD) approach and its hardware design. The target domain is originally production lines in factories, but our application is currently expanding, such as anomaly detections in datacenter, home, and UAVs. One of the biggest issues when applying AI to industries is to prepare accurate training data sets before deployment, because noise pattern (e.g., vibration) fluctuates and status of products/tools varies with time. The proposed on-device learning approach learns normal patterns including noises in a deployed environment extemporarily to detect unusual ones, so no prior training is needed. In this talk, we will introduce the algorithm and its related technologies, such as simplified computation method, stable learning method, forgetting method, and accuracy improvement method for multiple normal patterns, in addition to the hardware design for the on-chip learning for edge and IoT devices. We will also introduce some use cases.
