Semantic bottleneck for computer vision tasks
This paper introduces a novel method for the representation of images that is
semantic by nature, addressing the question of computation intelligibility in
computer vision tasks. More specifically, our proposition is to introduce what
we call a semantic bottleneck in the processing pipeline, which is a crossing
point in which the representation of the image is entirely expressed with
natural language , while retaining the efficiency of numerical representations.
We show that our approach is able to generate semantic representations that
give state-of-the-art results on semantic content-based image retrieval and
also perform very well on image classification tasks. Intelligibility is
evaluated through user centered experiments for failure detection
GuessWhat?! Visual object discovery through multi-modal dialogue
We introduce GuessWhat?!, a two-player guessing game as a testbed for
research on the interplay of computer vision and dialogue systems. The goal of
the game is to locate an unknown object in a rich image scene by asking a
sequence of questions. Higher-level image understanding, like spatial reasoning
and language grounding, is required to solve the proposed task. Our key
contribution is the collection of a large-scale dataset consisting of 150K
human-played games with a total of 800K visual question-answer pairs on 66K
images. We explain our design decisions in collecting the dataset and introduce
the oracle and questioner tasks that are associated with the two players of the
game. We prototyped deep learning models to establish initial baselines of the
introduced tasks.Comment: 23 pages; CVPR 2017 submission; see https://guesswhat.a
