NeuroPlace: categorizing urban places according to mental states
Urban spaces have a great impact on how people’s emotion and behaviour. There are number of factors that impact our brain responses to a space. This paper presents a novel urban place recommendation approach, that is based on modelling in-situ EEG data. The research investigations leverages on newly affordable Electroencephalogram (EEG) headsets, which has the capability to sense mental states such as meditation and attention levels. These emerging devices have been utilized in understanding how human brains are affected by the surrounding built environments and natural spaces. In this paper, mobile EEG headsets have been used to detect mental states at different types of urban places. By analysing and modelling brain activity data, we were able to classify three different places according to the mental state signature of the users, and create an association map to guide and recommend people to therapeutic places that lessen brain fatigue and increase mental rejuvenation. Our mental states classifier has achieved accuracy of (%90.8). NeuroPlace breaks new ground not only as a mobile ubiquitous brain monitoring system for urban computing, but also as a system that can advise urban planners on the impact of specific urban planning policies and structures. We present and discuss the challenges in making our initial prototype more practical, robust, and reliable as part of our on-going research. In addition, we present some enabling applications using the proposed architecture

Detecting human Activities Based on a multimodal sensor data set using a bidirectional long short-term memory model: a case study
Human falls are one of the leading causes of fatal unintentional injuries
worldwide. Falls result in a direct financial cost to health systems, and indirectly,
to society’s productivity. Unsurprisingly, human fall detection and prevention is
a major focus of health research. In this chapter, we present and evaluate several
bidirectional long short-term memory (Bi-LSTM) models using a data set provided
by the Challenge UP competition. The main goal of this study is to detect 12 human
daily activities (six daily human activities, five falls, and one post-fall activity)
derived from multi-modal data sources - wearable sensors, ambient sensors, and
vision devices. Our proposed Bi-LSTM model leverages data from accelerometer
and gyroscope sensors located at the ankle, right pocket, belt, and neck of the subject.
We utilize a grid search technique to evaluate variations of the Bi-LSTM model and
identify a configuration that presents the best results. The best Bi-LSTM model
achieved good results for precision and f1-score, 43.30% and 38.50%, respectivel
