Abstract

The present invention provides a method for abnormal detection of fetal electrocardiogram driven by rough and reasonable granularity, comprising the following steps: S10 obtaining the eigenvalues ​​of all fetal electrocardiogram samples and constructing a decision information table of fetal state; Calculate the rough membership degree of the sample; S30 selects a reasonable neighborhood based on the PSO optimization algorithm; S40 uses the optimal neighborhood radius obtained in step S30 as the neighborhood radius of the local neighborhood decision-making rough set model in the step S20, and updates approximate set. A rough and reasonable granularity-driven fetal electrocardiogram abnormality detection method of the present invention identifies abnormal samples according to neighborhood information, respectively gives rough membership degrees of samples in different distribution situations, and provides a set of pseudo-category marks for label noise samples; introduces reasonable Granularity criterion, the particle swarm optimization algorithm is used to select the optimal neighborhood radius, and the upper and lower approximation sets are updated on the information table corrected according to the pseudo-category label.

Description

technical field [0001] The invention relates to the technical field of fetal electrocardiogram detection, in particular to a method for abnormal detection of fetal electrocardiogram driven by rough and reasonable granularity. Background technique [0002] Whether the fetus develops normally during pregnancy still mainly depends on ultrasound examination. B-ultrasound can judge the shape of the fetus through the playback of sonar, but the shape of the fetus cannot reflect the overall development. With the development of science and technology, the fetal electrocardiogram is born. The fetal electrocardiogram can capture the electrocardiographic activity of the fetus through the body surface, judge whether the fetal development is normal, and whether there is a possibility of fetal distress. It can play a certain role in guiding the health of the fetus. According to the information of the fetal electrocardiogram, the health status of the fetus in the womb can be effectively jud...
