The Risk-Sensitive Schrödinger Bridge: Is Not a KL Projection
Hamidreza Behjoo
The Schrödinger bridge owes its computational power to a single structural fact: by Girsanov's theorem the controlled problem is a Kullback--Leibler (KL) projection onto a fixed re…
Adaptive Path Integral Diffusion: AdaPID
Michael Chertkov, Hamidreza Behjoo
Diffusion-based samplers -- Score Based Diffusions, Bridge Diffusions and Path Integral Diffusions -- match a target at terminal time, but the real leverage comes from choosing the…
Sampling Decisions: Exact Path-Space Control for Physics-Informed Generative Sampling
Michael Chertkov, Hamidreza Behjoo, Sungsoo Ahn
Scientific generative models must turn tractable local decisions into globally correlated samples that respect physical constraints. We introduce Sampling Decisions, a finite-horiz…
Harmonic Path Integral Diffusion
Hamidreza Behjoo, Michael Chertkov
In this manuscript, we present a novel approach for sampling from a continuous multivariate probability distribution, which may either be explicitly known (up to a normalization fa…
Exact Fractional Inference via Re-Parametrization & Interpolation between Tree-Re-Weighted- and Belief Propagation- Algorithms
Hamidreza Behjoo, Michael Chertkov
Computing the partition function, , of an Ising model over a graph of \enquote{spins} is most likely exponential in . Efficient variational methods, such as Belief Propag…
