The Research of Improved Grey GM (1, 1) Model to Predict the Postprandial Glucose in Type 2 Diabetes

Figure 1

(a) Patient A: blood glucose levels of 2 hours after meal. The front 18 samples constituted the original blood glucose sequence. The following 6 samples are the prediction sequence. (b) Patient A: blood glucose levels of 72 hours. The front 200 samples constituted the original glucose sequence. The following 664 samples are the prediction sequence. (c) The prediction results of (b). The original blood glucose data are shown by the black curve. The improved GM (1, 1) prediction values are shown by the red curve. (d) The prediction results of (b). The original blood glucose data are shown by the black curve. The AR model prediction values are shown by the red curve.
