Machine Learning Hamiltonians are Accurate Energy-Force Predictors

ICML 2026poster

Recently, machine learning Hamiltonian (MLH) models have gained traction as fast approximations of electronic structures such as orbitals and electron densities, while also enabling direct evaluation of energies and forces from their predictions. However, despite their physical grounding, existing H…

Multimodal Crystal Flow: Any-to-Any Modality Generation for Unified Crystal Modeling

ICML 2026poster

Crystal modeling spans a family of conditional and unconditional generation tasks across different modalities, including crystal structure prediction (CSP) and *de novo* generation (DNG). While recent deep generative models have shown promising performance, they remain largely task-specific, lacking…

CEDe: A collection of expert-curated datasets with atom-level entity annotations for Optical Chemical Structure Recognition

NeurIPS 2022accept

Optical Chemical Structure Recognition (OCSR) deals with the translation from chemical images to molecular structures, this being the main way chemical compounds are depicted in scientific documents. Traditionally, rule-based methods have followed a framework based on the detection of chemical entit…
