Query: GN-Transformer: Fusing Sequence and Graph Representation for Improved
  Code Summarization   As opposed to natural languages, source code understanding is influenced by
grammatical relationships between tokens regardless of their identifier name.
Graph representations of source code such as Abstract Syntax Tree (AST) can
capture relationships between tokens that are not obvious from the source code.
We propose a novel method, GN-Transformer to learn end-to-end on a fused
sequence and graph modality we call Syntax-Code-Graph (SCG). GN-Transformer
expands on Graph Networks (GN) framework using a self-attention mechanism. SCG
is the result of the early fusion between a source code snippet and the AST
representation. We perform experiments on the structure of SCG, an ablation
study on the model design, and the hyper-parameters to conclude that the
performance advantage is from the fused representation. The proposed methods
achieve state-of-the-art performance in two code summarization datasets and
across three automatic code summarization metrics (BLEU, METEOR, ROUGE-L). We
further evaluate the human perceived quality of our model and previous work
with an expert-user study. Our model outperforms the state-of-the-art in human
perceived quality and accuracy.
