uqdeepnn 0.2.1

Deep-UQ is the most comprehensive uncertainty quantification toolkit for deep learning in PyTorch — 20+ UQ methods, scientific ML architectures, evaluation metrics, active learning, and physics constraints, all behind a unified predict_uq() API.

Install

pip install uqdeepnn

Quick Example

from deepuq.models import MLP
from deepuq.methods import LaplaceWrapper

model = MLP(input_dim=1, hidden_dims=[64, 64], output_dim=1)
# ... train as usual ...

la = LaplaceWrapper(model, likelihood="regression", hessian_structure="kron")
la.fit(train_loader)
result = la.predict_uq(x_test)
# result.mean, result.epistemic_var, result.total_var
