This research proposes a unified estimation framework that parameterizes the density ratio with a displacement field acting on a base distribution, so that density ratio estimation and displacement field estimation are obtained simultaneously through the same convex optimization problem.

UnverifiedTraditional Langevin dynamics relies on gradient information of the target distribution's density function and performs well when the density function is smooth and differentiable.74% similarUnverifiedThis study models the data selection problem as a high-dimensional regression scenario with multiple heterogeneous data sources, and employs a weighted ridge regression estimator to fuse these sources.73% similarUnverifiedThe key insight of this study is that when the likelihood function derived from the data model is known and differentiable, guided diffusion modeling can be used to sample the predictive distribution.73% similarUnverifiedThe conjugate moment measure proposes using a single convex potential function W to simultaneously characterize the sampling distribution and the transport map, offering a path for generative modeling that differs from mainstream diffusion models.73% similarUnverifiedCommonly used calibration methods include Platt Scaling (fitting a sigmoid function using logistic regression) and Isotonic Regression (fitting a non-parametric monotonic mapping using isotonic regression).72% similar
