Query: Commit2Vec: Learning Distributed Representations of Code Changes   Deep learning methods, which have found successful applications in fields
like image classification and natural language processing, have recently been
applied to source code analysis too, due to the enormous amount of freely
available source code (e.g., from open-source software repositories).
  In this work, we elaborate upon a state-of-the-art approach to the
representation of source code that uses information about its syntactic
structure, and we adapt it to represent source changes (i.e., commits). We use
this representation to classify security-relevant commits.
  Because our method uses transfer learning (that is, we train a network on a
"pretext task" for which abundant labeled data is available, and then we use
such network for the target task of commit classification, for which fewer
labeled instances are available), we studied the impact of pre-training the
network using two different pretext tasks versus a randomly initialized model.
  Our results indicate that representations that leverage the structural
information obtained through code syntax outperform token-based
representations. Furthermore, the performance metrics obtained when
pre-training on a loosely related pretext task with a very large dataset
($>10^6$ samples) were surpassed when pretraining on a smaller dataset ($>10^4$
samples) but for a pretext task that is more closely related to the target
task.
