Paper:
For bidirectional joint image-text modeling, we develop variational hetero-encoder (VHE) randomized generative adversarial network (GAN), a versatile deep generative model that integrates a probabilistic text decoder, probabilistic image encoder, and GAN into a coherent end-to-end multi-modality learning framework. VHE randomized GAN (VHE-GAN) encodes an image to decode its associated text, and feeds the variational posterior as the source of randomness into the GAN image generator. We plug three off-the-shelf modules, including a deep topic model, a ladder-structured image encoder, and StackGAN++, into VHE-GAN, which already achieves competitive performance. This further motivates the development of VHE-raster-scan-GAN that generates photorealistic images in not only a multi-scale low-to-high-resolution manner, but also a hierarchical-semantic coarse-to-fine fashion. By capturing and relating hierarchical semantic and visual concepts with end-to-end training, VHE-rasterscan-GAN achieves state-of-the-art performance in a wide variety of image-text multi-modality learning and generation tasks.

Review:
This paper proposes a combined architecture for image-text modeling. Though the proposed architecture is extremely detailed, the authors explain clearly the overarching concepts and methods used, within limited space. The experimental results are extremely strong, especially on sub-domains where conditional generative models have historically struggled such as images with angular, global features - often mechanical or human constructed objects. "Computers" and "cars" images in Figure 2 show this quite clearly. The model also functions for tagging and annotating images - performing well compared to models designed *only* for this task.
The authors have done a commendable job adding detail, further analysis, and experiments in the appendix of the paper. Combined with the included code release, this paper should be of interest to many. 
My chief criticisms come for the density of the paper - while it is difficult to dilute such a complex model to 8 pages, and the included appendix clarifies many questions in the text body, it would be worth further passes through the main paper with a specific focus on clarity and brevity, to aid in the accessibility of this work. 
As usual, more experiments are always welcome, and given the strengths of GAN based generators for faces a text based facial image generator could have been a great addition. The existing experiments are more than sufficient for proof-of-concept though.
Finally, though this version of the paper includes code directly in a google drive link it would be ideal for the final version to reference a github code link - again to aid access to interested individuals. Being able to read the code online, without downloading and opening locally can be nice, along with other benefits from open source release. However the authors should release the code however they see fit, this is more of a personal preference on the part of this reviewer.
To improve my score, the primary changes would be more editing and re-writing, focused on clarity and brevity of the text in the core paper.
