## Motivation `FrozenTrial` can now be passed to objective functions thanks to https://github.com/optuna/optuna/pull/1503. Additional documentation could be helpful, e.g. that changes to user attributes are not persisted, actually, that those...
## Motivation A `crossover` parameter is to be added to the NSGA-II sampler as seen in https://github.com/optuna/optuna/pull/2903. This PR expects a follow up PR that addresses the following https://github.com/optuna/optuna/pull/2903#issuecomment-964736529. -...
## Motivation Trial post processing was recently introduced in #2134 . Similarly, we could introduce trial pre processing with something along `BaseSampler.before_trial`. Samplers that would benefit from this would include...
## Motivation The objective function type hint says that its parameter should be of type `Trial`. However, https://github.com/optuna/optuna/pull/1503 will allow `FrozenTrial`s (which will derive from `BaseTrial` but not `Trial`) to...
This is a wrapper for the [Visual Genome](http://visualgenome.org/) dataset that I am currently working on. Initially planning to support Region Descriptions (bounding boxes with captions) only but will be grateful...
