Missing data imputation using the exact conditional likelihood of DLVM
We're comparing the sampling methods to fill in missing parts of images by looking at the original images alongside versions where some fraction of pixels have been randomly changed.
- For MNIST dataset:
- For OMNIGLOT dataset:
Here we show some results about the imputation performance for different percentages of missing data.
Finally, we challenge the model by different initializations of the missing parts and we explore the the imputation performance.
