LatentFlow framework enables exact conditional sampling for stochastic processes

Researchers have developed LatentFlow, a novel framework designed to condition stochastic processes without requiring neural approximations or training. This method treats stochastic processes as deterministic transformations of a latent innovation, simplifying conditioning to latent-space inference. By pulling likelihoods back through this transformation and sampling from the resulting latent law, LatentFlow enables exact conditional sampling. This approach allows for rapid conditioning across diverse model classes, including spatial priors, nonlinear dynamics, scientific models, and neural processes, all executable on a standard CPU. AI

IMPACT This framework could streamline the development and application of complex AI models by simplifying the conditioning of stochastic processes.

    LatentFlow: A General Framework for Conditioning Stochastic Processes

    Stochastic-process models are, as a rule, far easier to simulate than to condition. Non-linear observations, non-Gaussian likelihoods, black-box information, and global constraints all induce intractable conditional laws, requiring bespoke, model-specific constructions. We introd…
