### Discussed in https://github.com/facebook/Ax/discussions/2333 Originally posted by **JingDang99** April 7, 2024 [Ax](https://github.com/facebook/Ax/tree/main)/[tutorials](https://github.com/facebook/Ax/tree/main/tutorials) /saasbo.ipynb when I use this, especially for this line: --------------------------------------------------------------------------- DataRequiredError Traceback (most recent call last) Cell In[77],...

#2417 shows that parameter constraints in string form are not properly parsed if there are spaces between the weights and the names of the parameters. Since we don't allow spaces...

Return (inv) root of KroneckerProductAddedDiagLinearOperator as lazy

1

This is a clone of https://github.com/cornellius-gp/gpytorch/pull/1430 Previously, `_root_decomposition` and `_inv_root_decomposition` were returning the (inv) root from the eigendecomposition as a dense tensor, which can be inefficient. This now returns the...

# 🚀 Feature Request Currently, there are a number of functions in the `torch` namespace that are not registered to dispatch to `LinearOperator`. Closing this gap will be necessary to...

[RFC] "Unrolled" representation of multi-task MVN

7

Currently, the interleaved/non-interleaved representation of MTMVN creates a bunch of headaches (in particular regarding indexing, scalarization, and performance). It would be nice to have a higher-level API that abstracts away...

Allow parameter constraints that involve `FixedParameter`s

2

Summary: Currently, we error out in `validate_constraint_parameters` if the list of parameters invovles at least one `FixedParameter`. That doensn't make a lot of sense, we should allow constraints as long...

Introduce methods registry

2

Summary: This is useful to send information about which method to run as python primitives over the wire. For now this contains a simple `Sobol` method for illustrative purposes. Differential...
