Document Type and Number:
WIPO Patent Application WO/2019/006631
Kind Code:
A1
Abstract:
A quality evaluation method and apparatus, a model establishment method and module, and a wearable device, wherein the quality evaluation method comprises: acquiring a quality evaluation model of a biological signal to be evaluated (301), wherein the quality evaluation model is established according to the establishment method of the quality evaluation model; acquiring a characteristic vector of the biological signal to be evaluated (302); performing, according to a pre-set dimension reduction method, dimension reduction processing on the characteristic vector of the biological signal to be evaluated, so as to obtain a characteristic vector corresponding to the quality evaluation model (303); and substituting the characteristic vector corresponding to the quality evaluation model into the quality evaluation model, and calculating a signal quality index of the biological signal to be evaluated (304). By means of the method, the characteristic vector of the biological signal in a training set is subjected to dimension reduction processing, thereby removing redundant information therein, and the quality evaluation model of the biological signal is acquired according to the characteristic vector after the dimension reduction processing, in order to acquire the signal quality index that accurately characterizes the signal quality when quality evaluation is performed on the biological signal.
