we give a Fuzzy Entropy Weight. For crisp numbers, the calculation of the entropies is very straightforward. Usu-ally we will use the following formula: (13) E(i) = −K Xm i=1 x ij lnx ij, where K is a constant. While for fuzzy numbers, we could not use the above formula to calculate the entropies of fuzzy numbers directly.
the concept of fuzzy entropy [8] have been popular in recent years. Fuzzy entropy is an extension of Shannon’s definition and its meaning is quite different from the classical Shannon entropy due to the fact that fuzzy entropy contains vagueness and ambiguity uncertainties, while Shannon entropy contains randomness uncertainty [9].

Assume we are considering the binary cross-entropy (so, i = 1) for one component of the fuzzy classification desired output. Assume the model's output is probability p and the desired output is probability q. Naturally, p and q will have the range of [0,1].

Entropy is also a measure of the number of possible arrangements the atoms in a system can have. In this sense, entropy is a measure of uncertainty or randomness . The higher the entropy of an object, the more uncertain we are about the states of the atoms making up that object because there are more states to decide from.
