Abstract

The invention discloses a health status evaluation system based on deep learning of multidimensional physiological big data, which utilizes a non-supervised convolutional neural network to extract features of physiological time-series data, and then utilizes multivariate Gaussian distribution for feature abnormality detection. The results show that it is an efficient anomaly detection system for physiological signals that can learn high-level features of signals from original physiological signals and multivariate Gaussian distribution anomaly detection. Users can identify certain early symptoms and take corresponding preventive measures in advance to reduce the risk of disease.

Description

technical field [0001] The present invention relates to medical testing equipment. Background technique [0002] In recent years, our life has become more and more closely connected with various smart devices, and modern life is increasingly inseparable from these smart devices. Using these smart devices, people nowadays can record various physiological signals anytime and anywhere, such as blood pressure, blood sugar, EEG, ECG, EMG, body temperature, breathing and other physiological signals. By analyzing these signals, we can understand Some information about the current state of our bodies. [0003] However, the incidence of various types of chronic non-communicable diseases is increasing. One of the reasons is the relative shortage of medical resources. People with a fast pace of life often go to the hospital for examination and treatment after they have serious physical problems, which leads to delays in treatment. Contents of the invention [0004] It is an object...
