WebOne of the most common problems in science is to investigate a function describing a system. When the estimate is made based on a classical mathematical model (white-box), the function is obtained throughout solving a differential equation. Alternatively, the prediction can be made by an artificial neural network (black-box) based on trends … WebMar 21, 2024 · Traditional approaches for density estimation (such as here) are based on the preliminary choice of a statistical model of the function and subsequent fitting on its parameters. For example, a neural network outputs the mean (μ) and the standard deviation (σ) parameters would be sufficient to describe the density function of a normal ... cross green asphalt plant WebMay 14, 2024 · Abstract.
