Fig. 2From: Differentiating novel coronavirus pneumonia from general pneumonia based on machine learningThe weight curves of 34 features based on ReliefF algorithm. The X-axis represents the numbers of features. The Y axis represents the weights of different features at different times. The algorithm run 1000 times represented by curves with different colors. The dark straight line represents weight = 0.11, which is the proposed threshold TBack to article page
