1. 8:35 - 9:25Machine Learning Basics and Its Applications to Internet-of-Things, Hiroshi Maruyama, Preferred Networks

Abstract: Statistical machine learning is expanding its application areas to almost all domains in the society. At the same time, this new technology changes the landscape of Information Technology in full range, from hardware architecture, software frameworks, system development processes, to business models. This talk first provides the basics of statistical machine learning, focusing on the similarities and differences with traditional IT. Then, we will explore how statistical machine learning can be applied to various domains. In particular, we will focus on connected embedded systems, also known as Internet-of-Things, because ti will be the area that will be most affected by the introduction of statistical machine learning.

2. 9:25 - 10:15Machine-learning-enabled Design Space for Energy-efficient Mixed-signal Inference Systems, Naveen Verma, Princeton University

Abstract: With increasing amount, diversity, and significance of data in our lives, machine-learning algorithms are giving us unprecedented capabilities to extract high-value inferences, based on models constructed from the data itself. This has been particularly enabling in sensor applications, where the physical processes deriving embedded signals are often not well understood. But, to address the severe energy constraints in these applications, we are also finding that machine-learning algorithms give rise to substantial opportunities to relax implementation requirements, enabling aggressive energy-saving and throughput-enhancing mixed-signal architectures. This presentation starts by reviewing the key attributes of machine-learning algorithms, and the relaxations that arise, specifically from data-driven model adaptation and statistical optimization. Then, considering silicon prototypes, we look at how these can be exploited in architectures to address system-design challenges, such as the energy of sensor acquisition as well as the energy and latency of memory accessing.

3. 10:35 - 11:25Designing Efficient Deep Learning Accelerators: Challenges and Opportunities, Joel Emer, MIT/NVidia

Abstract: Deep convolutional neural networks (CNNs) are widely used in modern AI systems for their superior accuracy, but at the cost of high computational complexity. The complexity comes from the need to simultaneously process hundreds of filters and channels in the high-dimensional convolutions. This computation not only requires a large number of arithmetic operations, but also a correspondingly large amount of data, creating significant data movement both on-chip and off-chip, which is even more energy consuming than the computation. Furthermore, deep learning is not a single static algorithm but a set of algorithms that not only change with application but are evolving rapidly. Combined, these factors present not only challenges on throughput and energy efficiency to the underlying processing hardware, but opportunities for architectural and implementation innovation. In this talk I will review some of the sources of these challenges and outline a number of the avenues available for addressing them, including optimizing the pattern of use of data, exploiting the data’s statistics, and hardware/algorithm co-design. Along the way, I will present a framework that allows for an intuitive characterization and energy analysis of alternative ways to orchestrate data movement.

5. 13:30 - 14:20Deep Learning for Mobile and Embedded Devices, Raheel Khan, Qualcomm

Abstract: Deep learning techniques are increasingly popular in applications such as image understanding, speech recognition and natural language processing and for processing sensor data in IoT devices. Deep learning, however, comes with significant computational complexity, which has prevented its broad adoption in mobile and battery power devices. Recent advances in low-power algorithmic techniques and in specialized architectures for deep learning reduce the energy cost for deep learning technique, thereby extending the range of applications where such techniques are feasible. After an introduction into deep learning—both for training networks and for inference-- this tutorial will present an overview of processing architectures for mobile and embedded devices. We will also review algorithmic innovations that enable energy efficient accelerators that offer 100x lower power consumption without any noticeable degradation of performance. The tutorial will also preview some of the relevant advances in deep learning for embedded devices.

6. 14:20 - 15:10Vision-Centric Devices at the Network Edge using Deep-Networks and Computer Vision, David Moloney, Intel/Movidius

Abstract: Always on vision processing in embedded applications is very challenging from the point of view of top-line operations/sec/W equally even where power consumption is not the overriding concern heat from power dissipation is an important consideration. In order to meet these constraints Movidius Myriad Vision Processing Units (VPUs) have used a balanced approach combining an array of SHAVE VLIW processors with Vector and SIMD capabilities for kernels requiring up to 10s of operations per pixel, hardware acceleration for kernels requiring 10s-100s of operations per pixel fed by a multicore memory subsystem for high sustained rather than peak performance. The design methodology used throughout was based on a focus on parallelism and modest clock rates combined with standard cell libraries and generated single-ported SRAM instances rather than custom macros, with the exception of the register files where there was a significant advantage to designing a macro owing to the high number of ports on the 128-bit Vector Register File (VRF). The design has evolved significantly over 3 generations of process technology, from 65nm LP, to 28nm HPC and now 16nm FF. Equally the power management strategy and use of power islands will be detailed with a view to the applications requirements in VR/AR/MR, robotics/drones, security cameras and wearables. These use cases and key computational kernels will be illustrated with relevant system diagrams, key kernels and metrics across computer vision and CNN networks.
