GaussianProductOp.ProductAverageConditional - 实验质量带低于推荐的质量带（预览）

Question

我有一个非常简单的规则，但我已经遇到了质量范围问题。有人可以解释为什么会这样吗？我已阅读有关 Quality bands 的文档，但我不明白。

这是我编写的产生警告的代码：

Gaussian BornYoungPerLitterDist = new Gaussian(5.5, 0);
Gaussian BirthRateDist = new Gaussian(0.004102103451, 0.00000144);

Variable<double> BornYoungPerLitter = Variable.Random<double, Gaussian>(BornYoungPerLitterDist);
Variable<double> Birthrate = Variable.Random<double, Gaussian>(BirthRateDist);

InferenceEngine engine = new InferenceEngine();
Gaussian Born = engine.Infer<Gaussian>(BornYoungPerLitter * Birthrate);
Console.WriteLine(
    "Born Mean: {0:f10}, Standard Deviation: {1:f10}",
    Born.GetMean(),
    Math.Sqrt(Born.GetVariance())
);

警告是：

Compiling model...compilation had 1 warning(s).
  [1] GaussianProductOp.ProductAverageConditional(vdouble2_use_B, vGaussian0, vGaussian1) has quality band Experimental which is less than the recommended quality band (Preview)

Answer 1

此问题已在 Infer.Net 的 Github 存储库中得到解答。

截至 2019 年 1 月，该功能仍在开发中，因此始终会引发警告。

This happens because the code that implements a product of Gaussian variables (GaussianProductOp) is in an early stage of development. If you want to disable the model compiler errors and/or the warnings, set the options on engine.Compiler.
