Keynote 1
Day 1, May 30th, 09:00 - 10:00
Fahim Kawsar (Nokia-Bell Labs)
Title: Computational Behavior Modelling for the Internet of Things
We are observing a monumental effort from the industry and academia to make everything connected. Naturally, to understand the needs of these connected things, we need a better understanding of humans and where, when, and how they interact. This behavioural understanding would help us to create digital services and capabilities that fundamentally change the way we experience our lives. In this talk, I will explore the system and algorithmic challenges in modelling human behaviour. I will discuss how mobile and wearable devices together with the wireless network can be used as a multi-sensory computational platform to learn and infer human behaviour and to design user-centred connected services across Enterprise, Urban City and Lifestyle.

Title: Challenges for evolution of connected cars
Automotive experts predict that between 2025 and 2035, people will be able to sleep in a car. In the morning, the car will recognize your face and automatically open the door. Simply tell the car your destination and she will brief your schedule, read your favorite book, or you can just take a nap, all while the car driving herself. To realize this future connected car, we have a lot of technological challenges. An autonomous car needs to locate itself and detect vehicles and pedestrians in a split second with limited sensor hardware such as camera and radar in a diverse conditions, even under low illuminations and rainy and snowy weather . To recognize the user, a convenient and reliable user authentication method such as face recognition is required which withstands spoofing attempts. An intelligent voice interface for safe driving could only be possible with extreme noise robustness and flexible understanding of natural language. Successful implementation of these functions will have huge computational needs leading a challenge of designing innovative processor architecture. In this talk, we would like to overview the some of the key technical challenges, recent developments across academia and industry, and describe some of our efforts to address these challenges.
