Compressed Neural Network for Thermal Array-Based Fall Detection System on Embedded AI

초록

Fall incidents may lead to more serious health issues if not promptly treated. Existing fall detection systems mostly use cameras and are considered a privacy-intrusive approach. Thermal array sensors are considered a privacy-friendly device that does not raise discomfort for users. In this study, we presented a fall detection system using a thermal array sensor with three different deep learning approaches: LSTM, BiLSTM, and GRU. Our model is optimized using the pruning method to further efficiently deployed into Embedded AI. Our result shows that BiLSTM has the most promising result by 99.93% accuracy, 99.73% precision, and 0.057% False Alarm Rate (FAR).
