Replace the unresolved small jumps of an infinite-activity stable Levy noise source in a neural SDE or stochastic optimizer with one Gaussian increment whose variance equals the discarded jump variance. Simulate only jumps above the cutoff exactly or by Poisson sampling, retaining the large-jump distribution while obtaining the paper's O(\varepsilon) Wasserstein error instead of the naive O(\varepsilon^{1-\alpha/2}) error.

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.

Replace independent Gaussian diffusion noise across sequence positions with a positive, persistent variance chain and conditionally Gaussian perturbations. This gives the denoiser exposure to heavy tails and volatility clustering without requiring a more expressive neural architecture; keep the denoiser blind to the realized variance when the goal is for generated samples to retain this structure.

Build a Schrödinger-bridge solver that represents the two Sinkhorn scaling factors as solutions of forward and backward Kolmogorov PDEs, rather than requiring explicit transition-density evaluation. Enforce an oblique Neumann condition on the backward factor and a normal no-flux condition on the forward factor, allowing degenerate diffusion and hard domain boundaries to be handled directly.

Train a neural finite-time Hamiltonian-style path from an easy base density to a Boltzmann target by minimizing its generalized nonequilibrium work. The work is a path-space log-density ratio, so its mean is a forward KL divergence up to a constant and the endpoint marginal mismatch is bounded by the same quantity. Unlike an uncorrected neural sampler, this produces a global proposal whose bias and overlap can be measured quantitatively.

Use an online estimate of the target distribution's remaining coordinate dependence to choose diffusion step sizes instead of using a uniform timestep grid. Take large jumps when the current state is nearly coordinate-factorized and shorten the step when the denoiser detects strong cross-coordinate dependence, targeting the paper's dependence-adaptive discretization scaling.

Modify a diffusion sampler over a complete scenario trajectory z by exponentially tilting its prior toward a learned failure score s(z), rather than conditioning independently on environment and execution variables. The resulting sampler spends more evaluations in rare failure regions while preserving an explicit importance weight for estimating probabilities under the original distribution.

Use the OU process driven by multiple dichotomous noises as a bounded colored-noise module for latent-variable or diffusion sampling.

Turn the paper's self-fictitious-play process into a learned sampler for latent training examples or diffusion states. A controller network generates trajectories using a best response to a slowly updated occupancy belief, and the belief is updated from the controller's own states with an exponential occupation-measure update. The slow update prevents abrupt feedback loops while the controller continually adapts toward underrepresented regions.

Replace backpropagated gradients in a Langevin sampler with a simultaneous-perturbation estimate obtained from two noisy evaluations of a neural energy or simulator-defined negative log-density.

Replace stepwise gradient evaluation in a Bouncy Particle sampler over neural-network parameters with deterministic windows.

Modify the probability-flow ODE of a reflected diffusion so that its learned velocity is tangent to the constraint boundary. Use an exact tangent projection for box or sphere constraints, or a smooth boundary-collar correction for general domains, and train with an additional penalty on the predicted normal flux. This prevents numerical trajectories from leaving the domain and targets the no-flux structure directly instead of clipping samples after each solver step.

Represent a rare transition in a neural latent space by a controlled path whose drift is optimized directly, instead of obtaining it by reversing the relaxation dynamics. Learn a state-dependent mobility or diffusion matrix so that the sampler allocates noise and control effort according to the local stochastic geometry. This should improve generation of low-probability transitions in nonequilibrium world models and reduce the number of failed trajectories.

Replace repeated rejection sampling from a neural proposal P with a Poisson race that selects one proposal candidate with exactly the target distribution Q. Candidate i receives a Poisson arrival time A_i and race score A_i divided by Q(X_i)/P(X_i); the smallest score wins. When Q is close to P in KL divergence, the selected index has low expected logarithmic rank, providing an adaptive compute budget instead of a fixed number of candidates.
