Surface electromyography (sEMG) is a State-of-the-Art (SoA) pathway for human-to-machine communication. Currently, the research goal is a more intuitive and fluid control, moving from signal classification of discrete positions to continuous control based on regression. The sEMG-based regression is still scarcely explored in research since most approaches have addressed classification. In this work, we propose the first event-based EMG encoding applied to the regression of hand kinematics suitable for working in streaming on a low-power microcontroller (STM32 F401, mounting ARM Cortex-M4). The motivation for event-based encoding is to exploit upcoming neuromorphic hardware to benefit from reduced latency and power consumption. We achieve a Mean Absolute Error of $8.8pm 2.3$ degrees on 5 degrees of actuation on the public dataset NinaPro DB8, comparable with the SoA Deep Neural Network (DNN). We use $9times$ less memory and $13times$ less energy per inference, with $10times$ shorter latency per inference compared to the SoA deep net, proving suitable for resource-constrained embedded platforms.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123474210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such systems are essential for those affected by diseases that modify their cognitive status and are not collaborative in using wearable or interactive systems (e.g., mobile apps to communicate). This is particularly true regarding neurodegenerative diseases that involve memory loss, cognitive decline, communication difficulties, behavioral changes, loss of independence, and physical complications. In response to the need of healthcare structures and caregivers to monitor this category of people during their in-home daily life, this paper proposes a nonintrusive system capable of detecting whether or not a person is in his/her room and if he/she is lying on the bed. Checking these conditions is of utmost importance, in particular, during the night to support the monitoring activity of caregivers and social-health operators taking care of people with Dementia and Alzheimer’s disease. The proposed system exploits WiFi’s Channel State Information (CSI) gathered by common access points installed in the room. CSI data are then used to train a Convolutional Neural Network (CNN) and a fine-tuning technique is applied to increase the generalization capabilities of the CNN model on new environments. In our experimental analysis, we trained the CNN model by collecting CSI data in four different rooms, from two subjects performing three distinct activities. Promising results have been achieved (accuracy >97.5%) in recognizing the target activities.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128176436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For effective ubiquitous deployment, the monitoring system should be easy to install and unobtrusive, reliable, low cost, tagless, and privacy-aware. Long-range capacitive sensors are good candidates, but they can be susceptible to environmental electromagnetic noise and require special signal processing. Neural networks (NNs), especially 1D convolutional neural networks (1D-CNNs), excel at extracting information and rejecting noise, but they lose important relationships in max/average pooling operations. We investigate the performance of NN architectures for time series analysis without this shortcoming, the capsule networks that use dynamic routing, and the temporal convolutional networks (TCNs) that use dilated convolutions to preserve input resolution across layers and extend their receptive field with fewer layers. The networks are optimized for both inference accuracy and resource consumption using two independent state-of-the-art methods, neural architecture search and knowledge distillation. Experimental results show that the TCN architecture performs the best, achieving 12.7% lower inference loss with 73.3% less resource consumption than the best 1D-CNN when processing noisy capacitive sensor data for indoor human localization and tracking.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128947856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial Intelligence (AI) applications typically collect them into centralized cloud infrastructures to run computationally intensive Machine Learning (ML) tasks. According to the emerging edge computing paradigm, instead, data preprocessing, model training and inference can be distributed among devices at the border of the local network, exploiting data locality to improve response latency, bandwidth usage and privacy, at the cost of suboptimal model accuracy due to smaller training sets. The paper proposes a cloud-edge framework for sensor-based AI applications, enabling a dynamic trade-off between edge and cloud layers by means of: (i) a novel containerized microservice architecture, allowing the execution of both model training and prediction either on edge or on cloud nodes; (ii) flexible automatic migration of tasks between the edge and the cloud, based on opportunistic management of resources and workloads. In order to facilitate implementations, a scouting of compatible device platforms for field sensing and edge computing nodes has been carried out, as well as a selection of suitable open-source off-the-shelf software tools. Early experiments validate the feasibility and core benefits of the proposal.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125932375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
