Problems solved by technology

[0006] For this reason, the first purpose of the present invention is to propose a method for processing measurement data, which solves the problem that the time series conversion algorithm in the prior art has too few features and information provided by time series segments after reducing the dimension of the time series, resulting in Motif discovery is inaccurate, which leads to technical problems of poor behavior recognition effect

Abstract

The present invention proposes a method and device for processing measurement data, wherein the method includes: generating an original sequence according to the measurement data at each measurement time point, dividing the original sequence into multiple time segments, and for each time segment, according to the time The measurement data of the measurement time point in the segment is expanded by using various algorithms to obtain the sequence of each dimension of the time segment. For each dimension sequence of the time segment, various features are extracted respectively to obtain the symbol vector of the time segment. The sequence of symbolic vectors generated by the symbolic vectors of time segments is processed by a motif discovery algorithm. It solves the technical problem that the time series conversion algorithm in the prior art reduces the dimensionality of the time series, so that the time series fragments provide too few features and information, resulting in inaccurate motif discovery, resulting in poor behavior recognition effect.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method and device for processing measurement data. Background technique [0002] With the popularization and improvement of mobile computing, network and sensor technology, identifying and tracking human activities has become an important application in the wearable field. Establish a human health map by tracking human behavior, and human behavior recognition includes independent behavior recognition and discovery such as sitting, standing, walking, running, cycling, and driving, as well as switching between various behavior states over a long period of time. [0003] The recognition of human behavior is based on the analysis and extraction of the measured sequence. The sequence here refers to an ordered data list formed over time, which reflects the state of a certain transaction / event over time. Status can be represented by real values ​​or symbols. [0004] In the prior ar...
