python - Is there an machine learning algorithm that combines classification and regression into one -

i have data set , wherein want predict component , along components need predict proportions seems me classification+regression. there python library that? there deep learning method ? understand task can done in 2 separate step there way combine these operations.

the solution format expect prediction must get

class : 34% class b : 46% class u : 20%

assuming classes exist z, , composition may have increase or decrease in number of classes.

latent class regression

the problem describing can solved latent class regression, or cluster-wise regression, or it's extension mixture of generalized linear models members of wider family of finite mixture models, or latent class models.

it's not combination of classification (supervised learning) , regression per se, rather of clustering (unsupervised learning) , regression. basic approach can extended predict class membership using concomitant variables, makes closer looking for. in fact, using latent class models classification described vermunt , magidson (2003) recommend such pourpose.
