The ELF model's SDE (Stochastic Differential Equation) sampler, specifically Algorithm 6, and its mathematical consistency with the paper's interpolation convention.

A research-oriented machine learning model, aiming for mathematical rigor and reproducibility. The implicit positioning is a theoretically sound and correctly implemented model.

A significant mathematical inconsistency is identified in the ELF paper's SDE sampler (Algorithm 6). While the clean-data coefficient 't_back' aligns with the paper's interpolation, the total noise level and marginal distribution at 't_back' do not match the theoretical requirement. The sampler m...
