Predicting seizures is challenging even with the availability of various sensors (gyroscopes, pulse rate sensors, heart rate monitors, etc). Electroencephalography (EEG) data can directly measure the activity of the brain and has been the choice of leveraging deep learning (DL) models for seizure prediction. Despite DL models achieving over 95% accuracy on retroactive clinical-grade EEG data, this performance fails to translate in real-world settings where the accuracy goes down to 66% - which warrants further investigation. Moreover, consumer-grade wearable EEG headsets, characterized by lower data quality and a varying number of channels across brands, present additional challenges. In this paper, we estimate the robustness of DL models which are trained on clinical-grade EEG data but tested on the type of data expected from consumer-grade wearable EEG headsets. We select the previously published model SPERTL to estimate its robustness when: (1) predicting with data from less leads/channels, (2) predicting when faced with streaming data, (3) evaluating performance on imbalanced data with more interictal segments. Our results are compared against baseline results from the SPERTL model which we have re-configured to operate independently of the number of channels with an average baseline area under the curve (AUC) score of 98.56%. Our results demonstrate that though the model is surprisingly resilient to streaming and noisy data, reducing the number of channels and a higher class imbalance have a more severe degradation. The AUC across all cross-validation sets degrades only by 2% and 3% on average for noisy and streaming data, respectively. However, a performance reduction, on average, is observed by 32% when imbalance is increased with higher percentage of interictal samples, and up to 16% when using lower number of channels.</p>","PeriodicalId":93158,"journal":{"name":"...

Existing solutions either require facial recognition or installation and maintenance of multiple units, or they lack long-term re-identification capability. In this paper, we propose a novel system - called EyeFi- that combines WiFi and camera on a standalone device to overcome these limitations. EyeFi integrates a WiFi chipset to an overhead camera and fuses motion trajectories obtained from both vision and RF modalities to identify individuals. In order to do that, EyeFi uses a student-teacher model to train a neural network to estimate the Angle of Arrival (AoA) of WiFi packets from the CSI values. Based on extensive evaluation using real-world data, we observe that EyeFi improves WiFi CSI based AoA estimation accuracy by more than 30% and offers 3,800 times computational speed over the state-of-the-art solution. In a real-world environment, EyeFi's accuracy of person identification averages 75% when the number of people varies from 2 to 10.</p>","PeriodicalId":93158,"journal":{"name":"...

In this paper, we propose Wi-Fringe, which is a WiFi CSI-based device-free human gesture recognition system that recognizes <i>named</i> gestures, i.e., activities and gestures that have a semantically meaningful name in English language, as opposed to arbitrary free-form gestures. Given a list of activities (only their names in English text), along with zero or more training examples (WiFi CSI values) per activity, Wi-Fringe is able to detect all activities at runtime. We show for the first time that by utilizing the state-of-the-art semantic representation of English words, which is learned from datasets like the Wikipedia (e.g., Google's word-to-vector [1]) and verb attributes learned from how a word is defined (e.g, American Heritage Dictionary), we can enhance the capability of WiFi-based named gesture recognition systems that lack adequate training examples per class. We propose a novel cross-domain knowledge transfer algorithm between radio frequency (RF) and text to lessen the burden on developers and end-users from the tedious task of data collection for all possible activities. To evaluate Wi-Fringe, we collect data from four volunteers in a multi-person apartment and an office building for a total of 20 activities.

However, testing and experimenting with real-world environments still poses a challenge for these applications since a realistic scenario of mobility is required. Typically, simulation tools use mobility trails to construct the network topology based on the mathematical formulation of a city mobility model, which attempts to emulate the real mobility of a given city. Another strategy is to use the real route of vehicles traveling to generate the model of mobility of a certain city; however, many studies available in the literature do not use the entire flow of vehicles that circulate in the city, acquiring data only of a small group of vehicles. Thus, in this work we intend to develop an infrastructure that would allow the extraction of the information of mobility from the vehicles of the countryside cities, in real time. This enables not only real-time vehicle monitoring but also the generation of traceability of real-time mobility. The results showed low battery consumption, as well as a low amount of mobile data usage.","PeriodicalId":93158,"journal":{"name":"...

This year we received 65 submissions in response to the call for papers. Each paper was reviewed by at least three experts in the field. After detailed on-line discussions with the Track Chairs, 24 papers were finally accepted, leading to an acceptance ratio of 37%. Specifically, the program covers important aspects of distributed computing in sensor systems, such as mobile crowdsourcing, energy efficiency and communication, routing, tracking and localization, security, and applications and outdoor testbed, to name a few. Additionally, there is one workshop that addresses challenging research topics in sensor networking. We believe the technical program will provide an exciting forum for researchers and practitioners to exchange cutting-edge ideas in distributed sensor systems.","PeriodicalId":93158,"journal":{"name":"...
