TLDR
In this paper, a bottom-up and top-down attention mechanism was proposed to enable attention to be calculated at the level of objects and other salient image regions, which achieved state-of-the-art results on the MSCOCO test server.Abstract:
Top-down visual attention mechanisms have been used extensively in image captioning and visual question answering (VQA) to enable deeper image understanding through fine-grained analysis and even multiple steps of reasoning. In this work, we propose a combined bottom-up and top-down attention mechanism that enables attention to be calculated at the level of objects and other salient image regions. This is the natural basis for attention to be considered. Within our approach, the bottom-up mechanism (based on Faster R-CNN) proposes image regions, each with an associated feature vector, while the top-down mechanism determines feature weightings. Applying this approach to image captioning, our results on the MSCOCO test server establish a new state-of-the-art for the task, achieving CIDEr / SPICE / BLEU-4 scores of 117.9, 21.5 and 36.9, respectively. Demonstrating the broad applicability of the method, applying the same approach to VQA we obtain first place in the 2017 VQA Challenge.read more

Answer Them All! Toward Universal Visual Question Answering Models
TL;DR: In this paper, the authors compare five state-of-the-art VQA algorithms across eight different datasets covering both natural image understanding and synthetic data sets and find that methods do not generalize across the two domains.

Learning to Generate Grounded Visual Captions Without Localization Supervision
TL;DR: This paper proposed a cyclical training regimen that forces the model to localize each word in the image after the sentence decoder generates it, and then reconstruct the sentence from the localized image region(s) to match the ground-truth.

Simple is not Easy: A Simple Strong Baseline for TextVQA and TextCaps
TL;DR: This paper argues that a simple attention mechanism can do the same or even better job without any bells and whistles of multi-modality encoder design, and finds this simple baseline model consistently outperforms state-of-the-art (SOTA) models on two popular benchmarks, TextVQA and all three tasks of ST-V QA.

Object-Difference Attention: A Simple Relational Attention for Visual Question Answering
TL;DR: An object-difference attention (ODA) is proposed which calculates the probability of attention by implementing difference operator between different image objects in an image under the guidance of questions in hand and Experimental results show those relational attentions have strengths on different types of questions.

Cascade Reasoning Network for Text-based Visual Question Answering
TL;DR: A novel Cascade Reasoning Network (CRN) is proposed that consists of a progressive attention module (PAM) and a multimodal reasoning graph (MRG) module that aims to explicitly model the connections and interactions between texts and visual concepts.

Long short-term memory
TL;DR: A novel, efficient, gradient based method called long short-term memory (LSTM) is introduced, which can learn to bridge minimal time lags in excess of 1000 discrete-time steps by enforcing constant error flow through constant error carousels within special units.

You Only Look Once: Unified, Real-Time Object Detection
TL;DR: Compared to state-of-the-art detection systems, YOLO makes more localization errors but is less likely to predict false positives on background, and outperforms other detection methods, including DPM and R-CNN, when generalizing from natural images to other domains like artwork.
