OpenAI has published research on advancements in generative models, detailing FFJORD and Glow. FFJORD introduces a method for scalable reversible generative models using continuous dynamics and Hutchinson's trace estimator for unbiased density estimation. Glow, an extension of previous reversible models, utilizes invertible 1x1 convolutions to generate realistic high-resolution images with efficient sampling and attribute manipulation capabilities. Additionally, OpenAI presented a quantitative analysis framework for decoder-based generative models using Annealed Importance Sampling to evaluate log-likelihoods and assess model performance, overfitting, and mode coverage.
