Query: MAN: Moment Alignment Network for Natural Language Moment Retrieval via
  Iterative Graph Adjustment   This research strives for natural language moment retrieval in long,
untrimmed video streams. The problem is not trivial especially when a video
contains multiple moments of interests and the language describes complex
temporal dependencies, which often happens in real scenarios. We identify two
crucial challenges: semantic misalignment and structural misalignment. However,
existing approaches treat different moments separately and do not explicitly
model complex moment-wise temporal relations. In this paper, we present Moment
Alignment Network (MAN), a novel framework that unifies the candidate moment
encoding and temporal structural reasoning in a single-shot feed-forward
network. MAN naturally assigns candidate moment representations aligned with
language semantics over different temporal locations and scales. Most
importantly, we propose to explicitly model moment-wise temporal relations as a
structured graph and devise an iterative graph adjustment network to jointly
learn the best structure in an end-to-end manner. We evaluate the proposed
approach on two challenging public benchmarks DiDeMo and Charades-STA, where
our MAN significantly outperforms the state-of-the-art by a large margin.
