OpenAI has released an improved version of their PixelCNN model, named PixelCNN++. This updated model incorporates several modifications to enhance performance and simplify its structure. Key changes include the use of a discretized logistic mixture likelihood for faster training, conditioning on whole pixels, and employing downsampling for multi-resolution structure capture. Additional optimizations like shortcut connections and dropout regularization were also implemented, leading to state-of-the-art results on the CIFAR-10 dataset. AI
