Abstract

The invention discloses an activity analysis method for hypertensive elder people based on multi-modal attention fusion. Multi-modal data features are fused, and attention representation of all modaldata is extracted based on an attention mechanism. Meanwhile, based on pulse waves and an electrocardio sensor, the method measures the real-time blood pressure of the hypertension elder people, calculates the variability of the blood pressure, analyzes the correlation between real-time activities and the blood pressure, and obtains daily activities suitable for the hypertension elder people. According to the analysis method, the attention mechanism is introduced based on a convolutional neural network model and a long-term and short-term memory neural network combination model, multi-modal feature extraction and fusion are realized, and the activity recognition precision can be effectively improved. Besides, the method analyzes the association between the real-time blood pressure and thedaily activities, and provides a basis for recommending reasonable daily activities for the hypertension elder people.

Description

technical field [0001] The invention belongs to the technical field of monitoring systems, and in particular relates to an activity analysis method for hypertensive elderly people based on multimodal attention fusion. Background technique [0002] Moderate physical activity is one of the important means of adjuvant treatment of chronic diseases such as hypertension, diabetes and osteoarthritis. Quantifying the intensity and type of daily activities of people with chronic diseases can help doctors or family members understand their activity patterns, regularity, type, and activity volume, improve the accuracy of health evaluation, and formulate more appropriate rehabilitation treatment strategies. With the development of wireless communication and wearable sensing technology, wearable sensing devices can collect data such as acceleration, heart rate, and electrocardiogram during human activities in real time. By analyzing the collected data, machine learning technology can be...
