    This example shows how to build an exponential degradation model to predict the Remaining Useful Life (RUL) of a wind turbine bearing in real time. The exponential degradation model predicts the RUL based on its parameter priors and the latest measurements (historical run-to-failure data can help estimate the model parameters priors, but they are not required).
