Verity: a wearable sensor system and intelligent processing for ambient assisted living of the elderly and infirm

Prof. Ping Jiang
The University of Hull, UK

Abstract:
Public healthcare is facing serious difficulties due to the rapidly growing aging population. Today, there are 7m homes with at least one senior person, with a further 1.2m disabled also living independently. These individuals have a desire to live independently rather than relying on intrusive care and support. They are also at higher risk of suffering from illness, accidents, and injuries in their day-to-day activities. Consequently there is a need for a system that can be conveniently wearable to monitor vital physiological parameters and check health conditions of a user, whilst communicates with health service providers. This talk will present a system Verity intended for the monitoring of the elderly and those requiring passive care, with a wrist-wearable wireless sensor node and a mobile platform to form a remotely accessible body area network. The system utilises a state-of-the art SoC, using an ultra-low power sensor interface and RF communication. Ambient/skin temperatures, accelerations and heart rate of the wearer are measured for real-time monitoring. Due to the high dimension and nonlinearity of the collected sensor data, it is necessary to develop effective behaviour recognition techniques which can find low-dimensional meaningful behaviour patterns hidden in the raw sensor data. The scientific problem for this non-intrusive care scenario is how to extract manageable low-dimensional features for behaviour classification and recognition from high dimensional, multi-modal, nonlinear, temporal and spatial log data of the sensors, which has been demonstrated to be difficult by using the classical techniques. In the Verity system, nonlinear dimension reduction is taken as a general framework for Bayesian estimation of behaviour patterns and abnormality detection is carried out in a low-dimensional space based on a hidden Markov model.

Forwarding Games in MANETs

Dr. Xiaohong Jiang
Future University Hakodate, Japan

Abstract:
We examine the optimal forwarding problem in mobile ad hoc networks (MANETs) based on a generalized two-hop relay with limited packet redundancy f (f-cast) for packet routing. We formulate such problem as a forwarding game, where each node individually decides a probability p (i.e., a strategy) to deliver out its own traffic and helps to forward other traffic with probability 1-p, while its payoff is the achievable throughput capacity of its own traffic. We derive closed-form result for the per node throughput capacity (i.e., payoff function) when all nodes play the symmetric strategy profiles, identify all the possible Nash equilibria of the forwarding game, and prove that there exists a Nash equilibrium strategy profile that is strictly Pareto optimal. Finally, for any symmetric profile, we explore the possible maximum per node throughput capacity and determine the corresponding optimal setting of f to achieve it.

Large Scale Visual Search

Dr. Qi Tian
University of Texas at San Antonio, USA

Abstract:
Coupled with the massive social multimedia data and mobile visual search applications, techniques towards large-scale visual search and recognition are emerging. To this end, the first part of this talk will review the key techniques in designing modern image search systems, including local feature representation and visual codebook construction, feature quantization and pooling, scalable index, spatial embedding and fast re-ranking. The second part of this talk will detail several cutting edge components toward achieving state-of-the-art performance, including visual pattern and phrase mining, supervised and optimal codebook construction, effective feature quantization and pooling, scalable spatial coding and fast re-ranking. Subsequently, this talk will go into four promising research topics targeting at real-world application of scalable visual search techniques, that is, mobile visual search with compact descriptors, visual query difficulty prediction for search engine designs, as well as the scalable spatial coding technique for real-time re-ranking of million-scale image corpus. Finally, this talk will sum up with the lessons learnt about developing scalable visual search systems, with our foresees for some prospective new topics, including zero-latency query manipulation, user-interaction in mobile query formulation, as well as objectbook construction for large-scale semantic-aware image retrieval.
