Keynote 1: Optimizing Device Placement in Machine Learning Workloads using Deep Reinforcement Learning



Baochun Li
UOT
 
Abstract: Training deep neural networks requires an exorbitant amount of computation resources, including a heterogeneous mix of GPU and CPU devices. It is critical to place operations in a neural network on these devices in an optimal way, so that the training process can complete within the shortest amount of time. The state-of-the-art in the literature uses a deep reinforcement learning method based on policy gradients to solve this problem, but we believe that there remains ample room for further improvements. In this talk, I will present our recent work published in ICML 2018 and NeurIPS 2018 that uses proximal policy optimization (PPO) and cross-entropy minimization to achieve significantly better performance than the state-of-the-art. Our experiments with several popular neural network training benchmarks have demonstrated clear evidence of superior performance: with the same amount of learning time, our algorithm leads to placements that have training times up to 60% shorter. This talk will be targeting a general audience, and will therefore include a brief tutorial on basic ideas in reinforcement learning algorithms.

Keynote 3: Data Access of Big Data: Solving the system bottleneck



Xian-He Sun
IIT
 
Abstract: We have entered the era of big data. However, the performance improvement of disk-based storage systems has been much slower than that of memory and network, creating a significant I/O performance gap. To reduce the performance gap, storage subsystems are under extensive changes, adopting new technologies and adding more layers into the memory/storage hierarchy. With a deeper memory hierarchy, the data movement complexity is increased significantly, making it harder to utilize the potential of the deep memory-storage hierarchy (DMSH) architecture. In this talk, we first show that storage data access is the most concerned performance bottleneck, even in a distributed mobile environment. Then, we present the development of Hermes, an intelligent, multi-tiered, dynamic, and distributed I/O caching system that utilizes DMSH to significantly accelerate I/O performance. Hermes is a US NSF supported large software development project. It extends HPC I/O stacks to integrated memory and parallel I/O systems, extends the widely used Data Format (HDF) and HDF5 library to understand users’ need and to achieve application-aware optimization in a DMSH environment. We will introduce the Hermes’ design and implementation; discuss its uniqueness and challenges; and present some initial design and implementation results.

Keynote 4: Exploring the Power of Pervasive Sensing for IoT Security and Smart Healthcare



Yingying Chen 
Rutgers
 
Abstract: With the advancement of mobile sensing and pervasive computing, extensive research is being carried out in various application domains such as Internet of Things (IoT), smart healthcare, connected vehicles, and their security issues. My research work explores the power of pervasive sensing technologies to benefit people’s daily lives and make impacts on the society advancement, especially in two emerging areas: IoT security and smart healthcare. Particularly, my group studies how to conduct user authentication on any solid surface for IoT applications and how to perform vital signs monitoring during sleep towards smart healthcare. The first part of my talk introduces the idea of extending user authentication beyond traditional touch screens to any solid surface for smart access systems (e.g., access to apartments, vehicles or smart homes). The system builds upon a touch sensing technique with vibration signals that can operate on surfaces constructed from a broad range of materials. It integrates passcode, behavioral and physiological characteristics, and surface dependency together to provide enhanced security for many IoT applications. The second part of my talk describes how to track human vital signs of breathing and heart rates during sleep, which serve as critical inputs for assessing the general physical health of a person and providing useful clues for diagnosing possible diseases. Different from previous work, our system re-uses existing WiFi network for tracking vital signs of breathing and heart rates concurrently without dedicated/wearable sensors or additional wireless infrastructure (e.g., USRP). The system exploits the fine-grained channel state information of WiFi signals to capture the minute body movements caused by breathing and heartbeats. The proposed system thus has the potential to be widely deployed in home environments and perform continuous long-term monitoring at a low-cost. Finally, I will share with you some new research directions I would like to pursue with the aim of influencing the future of smart homes and smart cities.
