Visual Semantic Navigation using Scene Priors

Wei YangXiaolong WangAli FarhadiRoozbeh Mottaghi
2019
ICLR

How do humans navigate to target objects in novel scenes? Do we use the semantic/functional priors we have built over years to efficiently search and navigate? For example, to search for mugs, we… 

The Curious Case of Neural Text Degeneration

Ari HoltzmanJan BuysLi DuYejin Choi
2019
ICLR

Despite considerable advances in neural language modeling, it remains an open question what the best decoding strategy is for text generation from a language model (e.g. to generate a story). The… 

Tactical Rewind: Self-Correction via Backtracking in Vision-And-Language Navigation

Liyiming KeXiujun LiYonatan BiskS. Srinivasa
2019
CVPR

We present the Frontier Aware Search with backTracking (FAST) Navigator, a general framework for action decoding, that achieves state-of-the-art results on the 2018 Room-to-Room (R2R)… 

DREAM: A Challenge Data Set and Models for Dialogue-Based Reading Comprehension

Kai SunDian YuJianshu ChenClaire Cardie
2019
TACL

We present DREAM, the first dialogue-based multiple-choice reading comprehension data set. Collected from English as a Foreign Language examinations designed by human experts to evaluate the… 

ATOMIC: An Atlas of Machine Commonsense for If-Then Reasoning

Maarten SapRonan Le BrasEmily AllawayYejin Choi
2019
AAAI

We present ATOMIC, an atlas of everyday commonsense reasoning, organized through 877k textual descriptions of inferential knowledge. Compared to existing resources that center around taxonomic… 

QuaRel: A Dataset and Models for Answering Questions about Qualitative Relationships

Oyvind TafjordPeter ClarkMatt GardnerAshish Sabharwal
2019
AAAI

Many natural language questions require recognizing and reasoning with qualitative relationships (e.g., in science, economics, and medicine), but are challenging to answer with corpus-based methods.… 

Declarative Question Answering over Knowledge Bases containing Natural Language Text with Answer Set Programming

Arindam MitraPeter ClarkOyvind TafjordChitta Baral
2019
AAAI

While in recent years machine learning (ML) based approaches have been the popular approach in developing end-to-end question answering systems, such systems often struggle when additional knowledge… 

QASC: A Dataset for Question Answering via Sentence Composition

Tushar KhotPeter ClarkMichal GuerquinAshish Sabharwal
2019
AAAI

Composing knowledge from multiple pieces of texts is a key challenge in multi-hop question answering. We present a multi-hop reasoning dataset, Question Answering via Sentence Composition (QASC),… 

On the Capabilities and Limitations of Reasoning for Natural Language Understanding

Daniel KhashabiErfan Sadeqi AzerTushar KhotDan Roth
2019
arXiv

Recent systems for natural language understanding are strong at overcoming linguistic variability for lookup style reasoning. Yet, their accuracy drops dramatically as the number of reasoning steps… 

Expanding Holographic Embeddings for Knowledge Completion

Yexiang XueYang YuanZhitian XuAshish Sabharwal
2018
NeurIPS

Neural models operating over structured spaces such as knowledge graphs require a continuous embedding of the discrete elements of this space (such as entities) as well as the relationships between…
