Review for NeurIPS paper: Exemplar VAE: Linking Generative Models, Nearest Neighbor Retrieval, and Data Augmentation

And since the ideas are rather incremental Meta-reviewer recommendations: The paper is borderline. R2 is considering increasing the score. R4 recommends rejection based on the lack of novelty compared to the VampPrior and that the paper conducts small-scale non-challenging experiments that doesn't require approximate nearest-neighbor search. He proposes to run the method on ImageNet but I believe this cannot be a condition for acceptance since not everyone has the potential for running such experiments. Furthermore, the paper already covers quite a lot in experiments with MNSIT, Omniglot, FashionMNIST and CelebA, and classification. I believe that R4's concern for novelty are successfully addressed in the rebuttal.
