Classifier-free guidance (CFG) is the default mechanism for conditional generation in diffusion models, but the distribution sampled by its deterministic guided dynamics is not captured by the usual product-distribution heuristic $p_0^ωq_0^{1-ω}$. We analyze CFG through the probability flow ODE and derive exact analytic path-integral representations of the induced distributions for both constant and time-dependent guidance.
arXiv:2606. 08953v1 Announce Type: new Abstract: Modern generative models often define an entire probability path from a simple prior to the data law, rather than only an endpoint map.

The paper introduces LOGSI, a method for logically guiding stochastic interpolants in generative models. LOGSI enables exact composition of conditional velocities for negation and exclusive disjunction, while handling conjunctions through score-based re-equilibration and Gaussian-path approximations. Experiments on image transfer and molecular editing demonstrate improved rule conformity and fidelity compared to baseline composed-velocity approaches.
arXiv:2606. 23920v1 Announce Type: cross Abstract: The task of compositional generation involves using a conditional generative model, trained only on a subset of the possible conditions, to produce samples from compositionally-defined target distributions such as a geometric combination of the source distributions.
