Recovering molecules from coarse-grained beads: free-energy-conditioned generative backmapping across chemical space

Read the original on arXiv Machine Learning →

The paper introduces juniper, a discrete denoising diffusion model that performs compositional backmapping from coarse‑grained (CG) beads to detailed molecular graphs. By conditioning on the octanol–water partition free energy, the model generates valid and unique molecules that closely match the target free‑energy distribution for two‑bead systems. This approach enables the conversion of CG screening results into candidate atomistic molecules for further study or synthesis.

Boltzmann-Expected Molecular Design with Decoupled Annealing Flows

arXiv:2607. 19519v1 Announce Type: cross Abstract: Most 3D properties relevant to molecular design, including free energies and shape descriptors, are $\textit{expectations}$ over the Boltzmann distribution over 3D configurations of a molecular graph.
