Estimators

sbi.neural_nets.estimators.ConditionalDensityEstimator	Base class for conditional density estimators.
sbi.neural_nets.estimators.ConditionalScoreEstimator	Score matching for score-based generative models (e.g., denoising diffusion).
sbi.neural_nets.estimators.ConditionalVectorFieldEstimator	Base class for vector field estimators.
sbi.neural_nets.estimators.FlowMatchingEstimator	Rectified flow matching estimator class that estimates the conditional vector field, \(v(\theta_t, t; x_o) = \mathbb{E}[\theta_1 - \theta_0 | \theta_t, x_o = x_o]\)
sbi.neural_nets.estimators.MixedDensityEstimator	Class performing Mixed Neural Density Estimation.
sbi.neural_nets.ratio_estimators.RatioEstimator	Base class for ratio estimators.
sbi.neural_nets.estimators.UnconditionalDensityEstimator	Base class for unconditional density estimators.
