 	ScoreGradELBO(n_samples; kwargs...)

-
-To reduce the variance of the gradient estimator, we use a baseline computed from a running average of the previous ELBO values and subtract it from the objective.

+Evidence lower-bound objective computed with score function gradient with the VarGrad objective, also known as the leave-one-out control variate.
 
 # Arguments
-- `n_samples::Int`: Number of Monte Carlo samples used to estimate the ELBO.
-
-# Keyword Arguments
-- `entropy`: The estimator for the entropy term. (Type `<: AbstractEntropyEstimator`; Default: `ClosedFormEntropy()`)
-- `baseline_window_size::Int`: The window size to use to compute the baseline. (Default: `10`)
-- `baseline_history::Vector{Float64}`: The history of the baseline. (Default: `Float64[]`)
+- `n_samples::Int`: Number of Monte Carlo samples used to estimate the VarGrad objective.
 
 # Requirements
 - The variational approximation ``q_{\\lambda}`` implements `rand` and `logpdf`.
 - `logpdf(q, x)` must be differentiable with respect to `q` by the selected AD backend.
 - The target distribution and the variational approximation have the same support.
-
-Depending on the options, additional requirements on ``q_{\\lambda}`` may apply.
