Keynote Speech:
New Era of Machine-Learning Driven Computer Architecture Research

Prof. Ahmed Louri
IEEE Fellow
George Washington University


ABSTRACT: While the computing world is reaching the limits of Moore's Law, demands for performance in excess of 1 million trillion floating-point operations per second (1 exaflops) are arising from novel paradigms to address applications in big data, machine learning and analytics from nearly countless resources. This computing challenge has never been as complex or as critically important as it is now. We are witnessing a new computing era calling for a migration from an algorithmic based compute world to a machine-learning based, data-intensive, memory-centric computing paradigm in which human capabilities are scaled and magnified. This paradigm shift is driven by the abundance of data (big data era) and the computing resources required to process it in application spaces spanning mobile/embedded computing, cloud/edge computing, and the internet of things. This new trend has reinvigorated computer architecture research. Researchers are considering new ways forward based on machine learning.

In this talk, I will first briefly describe the new mega trends in computer architecture research. I will then present our own research efforts and introduce a design paradigm that exploits the use of machine-learning to simultaneously improve power-efficiency, performance, reliability and security, for heterogeneous multicore architectures and on-chip communications. The aim is to provide insights and directions of integrating architectural innovations with machine learning in a holistic approach for future computer architecture research.

Keynote Speech:
Empowering The Next-Generation of Deep Learning

Prof. Tao Li
IEEE Fellow
University of Florida


ABSTRACT: Nowadays, deep learning techniques have achieved amazing success in numerous applications. Especially, they are being increasingly adopted in various real-world applications (e.g. autonomous vehicles, rescue robots, drones, smart home, IoT systems) to learn models from the raw data aggregated by edge devices, hence, providing accurate prediction and decision-making. Traditionally, due to its huge compute power and scalability, the cloud data center is often the best option for training and evaluating AI applications. With the increasing computing power and energy efficiency of mobile and edge devices, there is a growing interest in performing AI applications on these platforms. As a result, we believe the next-generation AI applications are pervasive across all platforms, ranging from central cloud data center to edge-side wearable and mobile devices. However, we observe several gaps that challenge the pervasive AI applications. First, the large size of such newly developed AI networks poses both throughput and energy challenges to the underlying processing hardware, which hinders ubiquitous deployment for many promising AI applications. Second, the traditional statically trained AI model in cloud data center could not efficiently handle the dynamic data in the real in-situ environments, which leads to low inference accuracy. Lastly, the training of AI models still involves extensive human efforts to collect and label the large-scale dataset, which becomes impractical in big data era where raw data is largely un-labeled and uncategorized. In this talk, I will present architecture and system support which enables next generation AI applications to become high efficient and intelligent. I will first introduce Pervasive AI, a user satisfaction-aware deep learning inference framework, to provide the best user satisfaction when migrating AI-based applications from Cloud to all kinds of platforms. Next, I will describe In-situ AI, a novel-computing paradigm tailored to in-situ AI applications. Furthermore, to tackle the big data challenge and achieve real intelligent (support autonomous learning), I will introduce Unsupervised AI, an unsupervised GAN-based deep learning accelerator.
