Replace an unconstrained Euclidean diffusion sampler plus projection with a controlled diffusion whose state always lies on an embedded manifold \(\mathcal M\). The neural controller predicts a tangent vector, while the stochastic forcing is also tangent; this preserves constraints during every intermediate denoising step and avoids the bias caused by repeatedly projecting off-manifold states.

Train a neural model through a sequence of progressively harder objectives, analogous to descending temperature from the exactly solvable infinite-temperature heat kernel. At stage k, initialize from the parameters learned at the previous stage and increase the continuation parameter only when the current residual and sampling diagnostics are stable. This should reduce optimization shocks and avoid repeatedly entering poor basins.

Replace the standard Gaussian affine reverse step with a conditional transport kernel learned from the forward transition. Given a noisy state x_{k+1}, the model predicts a full conditional distribution for x_k using a monotone conditional CDF or an autoregressive normalizing flow. This represents multimodal and state-dependent reverse transitions that cannot be captured by a single Gaussian mean and variance.

When candidate rewards are noisy, do not score every candidate once and immediately retrain on the apparent elites. Sequentially resample only candidates near the selection boundary and certify their ordering with a mean, median-of-means, trimmed mean, or sign test selected according to the observed tail behavior.

Modify a diffusion or score-based sampler so that boundary reflection is aligned with the model's admissible noise and control directions instead of using the Euclidean normal. At a boundary hit, reflect through the sub-Riemannian diffusion Gram matrix, preserving the anisotropic dynamics and preventing constraint corrections from injecting motion into inaccessible directions.

Estimate the local contraction rate along minibatch couplings of neural ODE or flow-matching trajectories instead of using one global Lipschitz lower bound.

Replace the arbitrary labelled target graph in each flow-matching pair by the node permutation that minimizes its Euclidean distance to the source graph. Construct the conditional interpolation and velocity target using this aligned representative, so the model learns transport in graph quotient space rather than wasting capacity on node-order mismatches.

Generate discrete configurations globally with an autoregressive model and then refine them using a continuous-time Markov chain of local single-site replacement moves. Use importance weights and the paper's normalized ESS to adapt the CTMC refinement budget and to reject training batches in which the proposal has collapsed onto a few modes.

Train one prompt-conditioned controller to solve a distribution of stochastic control tasks directly from the control objective, instead of generating an optimal trajectory dataset for every task. Use the probability-flow velocity to evolve particles deterministically, evaluate running and terminal costs on those particles, and backpropagate through the rollout to learn a reusable operator.

Replace IID latent or diffusion-noise samples used inside a neural expectation with a randomized low-discrepancy point set. Each randomized point has the correct marginal distribution, while the complete set covers the sampling domain more uniformly, reducing variance in minibatch loss and gradient estimates when the integrand is smooth in the base-noise coordinates.

Build a neural transport layer by parameterizing a convex potential whose gradient maps a semi-log-concave latent distribution into a compact convex data domain. Use the paper's dimension-free Lipschitz certificate to set the layer's Jacobian scale, initialize the potential, and reject or regularize parameter updates that create excessive curvature. The goal is a bounded-output transport module that is less sensitive to latent dimension than diameter-based spectral heuristics.

Parameterize a generative or density-evolving model as a composition of diffeomorphic optimal-mass-transport maps rather than unconstrained residual layers. Each layer transports one smooth positive density to another through a learned squared-distance OT map, while compositions provide a principled universal family for transformations connected to the identity.

Parameterize a continuous normalizing flow by a scalar potential and convert its gradient into the generalized p-optimal velocity field rather than using the usual quadratic-flow velocity. Train the field by matching velocities along straight source-target bridges, while retaining a terminal distribution loss so the flow remains useful when exact pointwise pairings are unavailable.

Replace a discretized Langevin sampler used with a neural energy model by a short underdamped diffusion proposal followed by exact path-space rejection correction.

Train one functional flow-matching network against conditional velocity targets formed from randomly varying finite-rank reconstructions, including sensor sets that are not nested across training examples. Decode predictions from two sensor layouts into a common function representation and add a cross-layout consistency penalty.

Replace the unconstrained rectified-flow velocity predictor with the gradient of a learned scalar potential. At every rectification round, fit the potential by weighted least squares to the current displacement field, then integrate the resulting conservative velocity from the source distribution to the target distribution. The gradient restriction is intended to eliminate non-transport rotational motion and improve convergence toward the quadratic optimal-transport coupling.

Train masked predictors with an explicit mixture of high-visibility masks, low-visibility masks, and a small atom at the fully masked input. High-visibility masks preserve ordinary denoising quality, while low-visibility and fully masked examples force the network to learn global mode frequencies that are invisible when nearly all context is shown. Tune the low-visibility mass using unconditional-mode recovery as an auxiliary validation metric.

Train a neural policy against task cost while penalizing its induced drift mismatch from a reference policy or offline-data dynamics model. Unlike action-space behavior cloning, the penalty weights deviations by the inverse diffusion covariance, so deviations in highly noisy directions are cheap and deviations in predictable directions are expensive. This gives a principled interpolation between reference preservation and task optimization.

Train one denoiser only for the nonquadratic residual distribution, then modify the diffusion sampler using an analytically computed quadratic Gaussian context. Changing $K$ at inference changes the target distribution without retraining the denoiser, enabling transfer across temperatures, masses, coupling strengths, and boundary conditions whenever those changes remain quadratic.
