Soft Sensor with Variational Inference Technique
Soft Sensor using supervised factor analysis with variational Bayesian
Soft Sensor using Gaussian mixture model with variational Bayesian
Just add the EM-based LDS method. Well, this is not numercial stable.
I think the basic works like parallelization the algorithm should be done by the enterprise. So, I'm not the brother mentioned in the Zhihu answer......
