GMM fitting with full covariance crashes unexpectedly unlike sklearn GMM fitting

7

I was trying to fit a GMM on data and kept getting the same error (with variying numbers for the batch and order): `_LinAlgError: torch.linalg_cholesky: (Batch element 3): The factorization...

Hello: The title kind of says it all. The gmm.model_.covariances variable is None for some reason for both of these models. I don't think this was the case in the...

Mini-batch training on GMM

3

Hi, I want to implement mini-batching training on GMM as discussed in #7 . However, I am little bit confused by the code `gmm.reset_parameters(torch.Tensor(fvectors[:500].astype(np.float32)))`. I am not sure whether it...

I would like to extend the compatibility with Python 3.11, torch 2.1, and pytorch-lightning 2.1.3. One fix was easy to make (e.g. change training_epoch_end into `on_training_epoch_end`). Another fix was about...

Hi, I trained the GaussianMixture model with pycave v3.2.1, however, after training a few epochs nll=nan.0 appears. And this situation happens occasionally, I would like to ask what is the...

GMM with Mini-Batches

1

Hi, Like [#7](https://github.com/borchero/pycave/issues/7) and [#19](https://github.com/borchero/pycave/issues/19) I am trying to fit a GMM to a large dataset [10^10, 50] and want to (need to) use mini-batching. However, in contrast to the...

Hello, I'm using pycave for a project where the data is unidimensional of size 8e9. The GPU options works well, and I'm splitting the data in "for loops" to do...
