FAQs

What is the core purpose of BLiTZ?

BLiTZ aims to simplify the creation of Bayesian Neural Network layers in PyTorch, allowing users to easily incorporate uncertainty and calculate the complexity cost of their models. It provides a straightforward way to integrate Bayesian features without disrupting standard PyTorch workflows.

How does BLiTZ help with prediction confidence?

By sampling weights from a distribution, BLiTZ enables the generation of confidence intervals for predictions, rather than just point estimates. This helps users understand the uncertainty associated with their model's outputs, leading to more reliable decision-making.

Is BLiTZ compatible with existing PyTorch models?

Yes, BLiTZ is designed for seamless integration with PyTorch. Its layers and utilities can be used within standard PyTorch network architectures, and it provides decorators like `variational_estimator` to handle Bayesian features while maintaining compatibility.
