March 29, 2021
Register now for "The Challenge of Multiplicity in Sensory AI Systems", a free IMOBILE ACM Chapter Webinar to be presented on Friday 9 April 2021 at 2 pm IST by Akhil Mathur, Principal Research Scientist at Nokia Bell Labs, Cambridge, Massachusetts, USA. (IMOBILE is the India Chapter of ACM SIGMOBILE.)
Duration : 1 hour
Abstract: The emergence of multiple sensor devices on or near a human body is opening up exciting possibilities for mobile sensing and AI research. This multiplicity allows us to leverage the sensor redundancy and high availability of multiple devices, thereby enabling rich, powerful, and collaborative sensing applications. However, this multiplicity also comes at the expense of increased system complexity. Two key factors contributing to this challenge are device and data variabilities, caused by several runtime factors, including device availability, sensing hardware, resource budget, and device placement. In this talk, I will present SensiX—a multi-sensory edge ML framework—which offers best-effort inference in multi-device environments. SensiX operates on two key functions, a neural translation operation for principled mapping of device-to-device data and a selection operation to systematically choose the right device(s) as a function of model accuracy. Collectively, SensiX automates the selection and transformation of heterogeneous sensor streams for accurate, robust, and energy-efficient execution of sensory models on mobile and wearable devices. I will end the talk by providing an overview of the future research directions for SensiX.
