We have included several additional baselines for both the synthetic energy experiments and conformer generation
New Synthetic Energy Baselines (DW4, LJ) (Section A):
Denoising Diffusion Sampler (DDS) [Vargas 2023],
Off-policy LogVariance [Richter 2023]
An ablation of Adjoint Sampling w/o Reciprocal Projection that only trains with sampled SDE trajectories and does not perform reciprocal projection.
New Metrics and Figures for (DW4, LJ) (Section A):
Effective sample size (ESS) and Evidence lower bounds (ELBO) [Zhang 2022, Blessing 2024].
Energy Histogram Plots
Run-time efficiency breakdown of Amortized Training (Section A).
New Amortized Molecular Conformer Baselines (SPICE, GEOM-DRUGS) (Section A):
iDEM [Akhound-Sadegh 2023] with 2 and 16 MC samples for estimating the loss.
Adjoint Sampling w/o Reciprocal Projection (ablation).
Molecular Data Details (Section B):
The distribution of molecular structures and some example conformers are described.
