Quantile Normalization 定义来自如下文献: 标准化/归一化 标准化(standardization)、归一化(normalization)两者总是被混着叫,实际是在做什么处理呢? 先看下Python库中的关于预处理的一些包: 其中包括了:scaling(缩放), centering(中心化), normalization(归一化), binarization(二值化)。 对于标准化和归一化对应的常...

In this study, min–max normalization was used as the data-scaling methods. When the information of each ship is defined as 𝑆(𝑥)S(x), the time corresponding to the starting point of the section is defined as 𝑆(𝑥𝑚𝑖𝑛)S(xmin) and the last point as 𝑆(𝑥𝑚𝑎...
This normalization is done with a softmax activation function (Figure 9). Imposing these constraints is important to obtain a working model, both to have an accurate point forecast and to have adequate quantile forecasts. In particular, the last constraint is necessary to stabilize the learning ...
All models are trained on the training set, and to reduce the complexity of training and improve the training efficiency of the models, a normalization method is used to normalize all data to a value between (0,1)(0,1). Each method is iterated for 200 epochs to ensure convergence of ...
