使用StandardScaler代替MinMaxScaler时获取损失函数的NaN是由于数据标准化过程中可能存在的数值溢出或除以零的情况导致的。 StandardScaler是一种常用的数据标准化方法,它通过将数据按特征列进行标准化,使得每个特征的均值为0,标准差为1。标准化后的数据服从标准正态分布,适用于大多数机器学习算法。

很多的 loss 函数都有 size_average 和 reduce 两个布尔类型的参数。因为一般损失函数都是直接计算 batch 的数据，因此返回的 loss 结果都是维度为 (batch_size, ) 的向量。
The MinMax block ignores any input value that is NaN, except when every input value is NaN. When all input values are NaN, the output is NaN, either as a scalar or the value of each output vector element. Examples expand all Find Maximum Value of InputExtended...

In the second part of this work, there given are some sufficient conditions for the fulfillment of an analogy of classical scalar inequalities that involve relations between minmax and maxmin. An illustrative example is worked out for a linear-quadratic type of vector-valued optimization with ...
