Application of a Cloud Model-Set Pair Analysis in Efficacy Assessment for Diabetic Ulcers

Table 4

Cloud weight of each index. Ex, En and He denote the expected value, entropy, and hyper entropy, respectively. Ex is the expected value of the cloud drop that can represent the qualitative concept. En reflects the dispersion degree of cloud drops, which also determines the certainty of cloud drops. He is the entropy of En. It reveals the uncertainty measurement of En that is used to settle confusion degree (see (6)). For the commonsense concept, He is smaller when the acceptance degree is higher. In the same way, He will be bigger if the concept cannot reach an agreement. After the test of (6), the distribution of Ex, En, and He in Table 4 is in accordance with the shape of cloud.
