Theres an example that kind of gets into it and I think will help you.有一个例子涉及其中，我认为会对你有所帮助。 It looks like you have to do your own scoring to get the exact probabilistic PCA implementation you're after for your data.看起来您必须自己进行评分才能获得数据所需的准确概率 PCA 实现。 Probably playing around with the results of an implementation similar to that will help you figure out your issues.可能使用类似的实现结果将帮助您找出问题。
