Do you have any code about PCA for classificatin in MATLAB or Python?

Hi, I need PCA (principle component analysis) code for classification. I would like to use it for fault diagnosis. Thus, the problem is multi-class not just binary-class. I would be grateful if...

How are unknown parameters of dynamic linear model (state space model) specified?

The main idea is to use multivariable time series (as observations) to predict a state variable (one dimension). Please find the attachments. For example time series mm (4 variables and 200...

For classification (fault diagnosis), what is the advantage of Bayesian Network vs. Naive Bay classifier?

Naive Bayesian classifier have just two layers, one for Faults and the other for Symptoms. But, some researcher use Bayesian Network for classification such as the attachment. On the other hand,...
