Reviews: Variational Structured Semantic Inference for Diverse Image Captioning

Originality: The proposed approach using syntactic and lexical diversity modelling within the latent space to generate diverse image captions is novel. Quality: To establish that the generated captions are diverse, various standard diversity metrics are measured for the proposed method in Tab. 2. Some qualitative results demonstrating diverse captions and diversity conditioned on different visual parse tree probabilities is shown in Figure 1 and 6. These experiments help justify the core components of the proposed approach. Clarity: The paper is well written and easy to follow. Careful illustrations in Figure 1 and 3 are used as an aid while describing the proposed method.
