Flow training in unconstrained space #585

Open michaeldeistler opened 2 years ago

michaeldeistler commented 2 years ago

This should happen only after we have moved to pyroflows

janfb commented 2 years ago

addition: would be great to add log transforms for bounded data, e.g., for reaction time data in NLE.

Removing the label because we will do this after the flowtorch port

janfb commented 6 months ago

More context: With #952 #957 getting fixed, it will be possible to add new density estimators, e.g., those from zuko.

Goal: some priors are bounded, but it can be beneficial to perform the density estimation in unconstrained space, e.g., add a transform that transforms the parameters to an unconstrained space before or after the flow.

I literally just implemented this for another project. It shouldn't be too hard.

bkmi commented 5 months ago

actually I will work on something else for now.

janfb commented 1 month ago

As we have @zuko flows now, this should be straight forward to implement. Nevertheless, I am removing the hackathon label for now as I don't think this will be doable before nor essential for the upcoming release.
