Machine Learning Systems: On-device AI and Beyond

Dr. Nicholas D. Lane (University of Oxford, UK)

Abstract: In just a few short years, breakthroughs from the field of deep learning have transformed how computational models perform a wide-variety of tasks such as recognizing a face, driving a car or translate a language. Unfortunately, deep models and algorithms typically exert severe demands on local device resources and this conventionally limits their adoption within mobile and embedded platforms. Because sensor perception and reasoning are so fundamental to this class of computation, I believe the evolution of devices like phones, wearables and things will be crippled until we reach a point where current -- and future -- deep learning innovations can be simply and efficiently integrated into these systems.

In this talk, I will describe our progress towards developing general-purpose support for deep learning on resource-constrained mobile and embedded devices. Primarily, this requires a radical reduction in the resources (viz. energy, memory and computation) consumed by these models -- especially at inference time. I will highlight various, largely complementary, approaches we have invented to achieve this goal including: binary “on-the-fly” networks, sparse layer representations, dynamic forms of compression, and scheduling partitioned model architectures. Collectively, these techniques rethink how deep learning algorithms can execute not only to better cope with mobile and embedded device conditions; but also to increase the utilization of commodity processors (e.g., DSPs, GPUs, CPUs) -- as well as emerging purpose-built deep learning accelerators.

3.2 Panel Discussion Regarding How to Establish Objective Gold Standard Measurements for Health Constructs.

Due to participants' increased willingness to wear wrist-worn sensors, the wrist remains a major contender for tackling problems related to health and medicine. Currently physical and sedentary activity are the only constructs with acceptable gold standard passive sensing measures (e.g. Actigraph measuring MVPA and Actipal measuring types of sedentary activity). We aim to begin the discussion to change that. We have put together a unique panel discussion comprising key individuals across government agencies, academia and industry surrounding "Defining Objective Gold Standard Measures for Health Outcomes." Our goal is to engage the research community in this important discussion, and perhaps identify a vision moving forward for technologist, behaviorist, engineers, and mHealth specialist.
