GPflow 不确定输入
GPflow uncertain inputs
GPflow 是否支持预测步骤中的不确定输入？训练步骤中的不确定输入怎么办？
我环顾四周，好像没有这方面的资料。
谢谢。

Currently, there is a good deal of back-end code that makes this easy, but the front-end functionality is not there yet. conditionals.py:uncertain_conditional() is designed for exactly this. It calculates the moment matched means and variances for Gaussian inputs, which is also what is needed for GPLVMs and variational uncertain input models. To train with this, one needs to implement a model using this conditional instead of the normal one, and similarly for testing.
Hope this helps.
