Detecting Human Activities Based on a Multimodal Sensor Data Set Using a Bidirectional Long Short-Term Memory Model: A Case Study

Abstract: 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… Show more

“…DCTs are essential and crucial for various applications in the field of medical science/engineering. In lossy compression of audio files, such as MP3, and images, such as JPEG, the small high-frequency elements may be discarded, and DCT is suitable [ 43 , 44 , 45 , 46 ].…”

“…Automated recognition of patterns in data by computers based on knowledge already obtained is called pattern recognition. It has applications in image analysis, information retrieval, signal processing, bioinformatics, data compression, statistical data analysis, computer graphics, and machine learning [27,31,33,[41][42][43][44].…”

“…In today's pattern recognition applications and methods, the convolutional neural network (CNN) structures represent a huge breakthrough in image analyzing. The CNN structures largely exploit the texture content and can be found at the core of everything from remote sensing to automated tumor segmentation (Mahmood et al 2017;Ullah et al 2018;de Assis Neto et al 2020;Cecotti et al 2020).…”
