lvae_prediction
Module containing pytorch implementations for obtaining predictions from an LVAE.
lvae_predict_mmse_tiled_batch(model, likelihood_obj, input, mmse_count)
#
Generate the MMSE (minimum mean squared error) prediction, for a given input.
This is calculated from the mean of multiple single sample predictions.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
model | LadderVAE | Trained LVAE model. | required |
likelihood_obj | LikelihoodModule | Instance of a likelihood class. | required |
input | torch.tensor | tuple of (torch.tensor, Any, ...) | Input to generate prediction for. This can include auxilary inputs such as | required |
mmse_count | int | Number of samples to generate to calculate MMSE (minimum mean squared error). | required |
Returns:
Type | Description |
---|---|
tuple of (tuple of (torch.Tensor[Any], Any, ...)) | A tuple of 3 elements. The first element contains the MMSE prediction, the second contains the standard deviation of the samples used to create the MMSE prediction. Finally the last element contains the log-variance of the likelihood, this will be |
