Acquisition jitter? #333

Open harrytianyz opened 4 years ago

harrytianyz commented 4 years ago

I think in previous versions GPyOpt allowed users to tune the parameter acqusition_jitter, which is the degree of exploration of the acquisitions function. In the current version acquisition_jitter is removed and can only be used for modular Bayesian Opitimization.

Does anyone know why they removed it? And also can I still tune jitter without using modular Bayesian Optimization?

As far as I am aware it wasn't removed, you would still pass it as a named argument to BayesianOptimization object. Does this give you an error, or is there any other reason you think it was removed?

In the documentationm jitter is no longer one of the parameters: [https://gpyopt.readthedocs.io/en/latest/GPyOpt.methods.html].. If I do pass it as argument there is no error, but I don't think it does anything either...

Ah, i see. That must be a side effect of some refactoring we did a while ago, when we separated code that handles optional parameters like that. I'll have a little think of how to bring this part of docs back. But I am pretty sure this parameter is still supported.
