PixelCNN++: Improving the PixelCNN with discretized logistic mixture likelihood and other modifications
OpenAI's PixelCNN++ achieves new image generation benchmarks with discretized logistic mixture likelihood.
Why it matters
Academic research milestone on generative modeling for images. While influential in deep learning history, this 2017 paper predates the transformer era and modern diffusion models that now dominate production AI, limiting immediate business relevance today.
