[FEATURE REQUEST]: Create a "best-practice" method for optimizing mixture weights, including optimizing over a simplex search space

FYI support for a `DerivedParameter` is added in https://github.com/facebook/Ax/pull/4142. This would allow specifying x6 as a function of the other parameters and using a sum constraint that `x1 + ......

[FEATURE REQUEST]: Create a "best-practice" method for optimizing mixture weights, including optimizing over a simplex search space

no, for now we require that the parameter constraints be specified in terms of the other parameters. That's a simple re-write of the constraint though

[Bug] MultiTaskGP without data

Thanks for flagging this. This appears to be an issue in `IndexKernel`: specifically, `InterpolatedLinearOperator` doesn't work when `left_interp_indices` and `right_interp_indices` are empty tensors. Would you mind opening an issue in...

[Bug]: MultiTaskGP Prediction when all_tasks is passed

Yeah these are related, but slight different issues. Currently, MultiTaskGP will create an index kernel with the number of tasks equal to the number of tasks in the training data,...
