[Documentation] Inaccurate and incomplete documentation for `SingleTaskMultiFidelityGP`
- The docstring for
linear_truncated
and the class docstring describe what the behavior would be if the default werelinear_truncated=False
. However, the default isTrue
. The model uses aLinearTruncatedFidelityKernel
, which isn't described at all. - It is not clear how data fidelities are to be interpreted. Does a higher number indicate higher fidelity? Can they lie outside [0, 1]? Do they have a cardinal or ordinal interpretation?
This came up in #2393 , and I spent a while myself trying to understand how fidelities should be specified and how they affect the kernel.
