Uncertainty-Calibrated Diffusion for Reliable 3D Molecular Graph Generation

arXiv:2606.01595v1 Announce Type: new Abstract: Bayesian inference provides a principled framework for modeling epistemic uncertainty in neural networks by treating predictions as distributions rather than deterministic values. Meanwhile, diffusion-based models for 3D molecular graph generation operate on fragile geometric structures governed by strict chemical constraints, making inference highly sensitive to uncertainty miscalibration. A largely overlooked issue is that epistemic uncertainty arising from the learned denoiser interacts with the aleatoric uncertainty intentionally injected dur

Why this matters
Why now

The increasing sophistication of AI models for scientific discovery, especially in molecular biology, necessitates robust methods for uncertainty quantification to ensure reliability and trust.

Why it’s important

Reliable 3D molecular graph generation with calibrated uncertainty is crucial for drug discovery, material science, and synthetic biology, where errors can have significant real-world consequences.

What changes

This advancement proposes a method to improve the trustworthiness and safety of AI-generated molecular structures by explicitly addressing and calibrating epistemic and aleatoric uncertainties.
