Mean path loss
WebMar 30, 2024 · we can give more accurate confidence level over the path loss mean value. Finally, we attempt to. combine ANN and Gaussian process models to build an optimal model in two key aspects: mean path. WebThe reference [ 1] describes an intrinsic loss as the automated derivation from the sampling distribution without subjective inputs. Whereafter, the entropy and Hellinger losses are suggested there as two appropriate distances between distributions, and their properties are studied especially for exponential families.
