Abstract: The present disclosure processes a user's medical data for each year to be input to a machine learning device for predicting dementia, and a data set composed of optimal features is constructed. The optimal features include at least information on the user's disease history, and the user's medical information for each year in the last 7 years or less. Precise prediction and diagnosis of dementia may be made by constructing the optimal features identified through experiments in the user's medical data for each year. Since the experimental results show that the prediction results of observing a disease history of 7 years or less may be the best, rather than observing medical information for a long period of time, the appropriate criteria may be suggested for predicting dementia.

Abstract: Embodiments of methods for multimedia annotation with sensor data (referred to herein as Sensor-rich video) includes acquisition, management, storage, indexing, transmission, search, and display of video, images, or sound, that has been recorded in conjunction with additional sensor information (such as, but not limited to, global positioning system information (latitude, longitude, altitude), compass directions, WiFi fingerprints, ambient lighting conditions, etc.). The collection of sensor information is acquired on a continuous basis during recording. For example, the GPS information may be continuously acquired from a corresponding sensor at every second during the recording of a video. Therefore, the acquisition apparatus generates a continuous stream of video frames and a continuous stream of sensor meta-data values. The two streams are correlated in that every video frame is associated with a set of sensor values. Note that the sampling frequency (i.e.
