OpenDialKG: Explainable Conversational Reasoning with Attention-based Walks over Knowledge Graphs

Association for Computational Linguistics (ACL)

We study a conversational reasoning model that strategically traverses through a large-scale common fact knowledge graph (KG) to introduce engaging and contextually diverse entities and attributes. For this study, we collect a new Open-ended Dialog ↔ KG parallel corpus called OpenDialKG, where each utterance from 15K human-to-human role-playing dialogs is manually annotated with ground-truth reference to corresponding entities and paths from a large-scale KG with 1M+ facts.

What makes a good conversation? How controllable attributes affect human judgments

North American Chapter of the Association for Computational Linguistics (NAACL)

In this work, we examine two controllable neural text generation methods, conditional training and weighted decoding, in order to control four important attributes for chitchat dialogue: repetition, specificity, response-relatedness and question-asking.

CNNs found to jump around more skillfully than RNNs: Compositional generalization in seq2seq convolutional networks

Annual Meeting of the Association for Computational Linguistics (ACL)

We test here a convolutional network (CNN) on these tasks, reporting hugely improved performance with respect to RNNs. Despite the big improvement, the CNN has however not induced systematic rules, suggesting that the difference between compositional and non-compositional behaviour is not clear-cut.

CoDraw: Collaborative Drawing as a Testbed for Grounded Goal-driven Communication

Association for Computational Linguistics (ACL)

In this work, we propose a goal-driven collaborative task that combines language, perception, and action. Specifically, we develop a Collaborative image-Drawing game between two agents, called CoDraw. Our game is grounded in a virtual world that contains movable clip art objects.

ELI5: Long Form Question Answering

Association for Computational Linguistics (ACL)

We introduce the first large-scale corpus for long-form question answering, a task requiring elaborate and in-depth answers to open-ended questions. The dataset comprises 270K threads from the Reddit forum “Explain Like I’m Five” (ELI5) where an online community provides answers to questions which are comprehensible by five year olds.

Miss Tools and Mr Fruit: Emergent communication in agents learning about object affordances

Association for Computational Linguistics (ACL)

Recent research studies communication emergence in communities of deep network agents assigned a joint task, hoping to gain insights on human language evolution. We propose here a new task capturing crucial aspects of the human environment, such as natural object affordances, and of human conversation, such as full symmetry among the participants.

Inferring Concept Hierarchies from Text Corpora via Hyperbolic Embeddings

Association for Computational Linguistics (ACL)

We consider the task of inferring is-a relationships from large text corpora. For this purpose, we propose a new method combining hyperbolic embeddings and Hearst patterns. This approach allows us to set appropriate constraints for inferring concept hierarchies from distributional contexts while also being able to predict missing is-a-relationships and to correct wrong extractions.

Translating Translationese: A Two-Step Approach to Unsupervised Machine Translation

Association for Computational Linguistics (ACL)

Given a rough, word-by-word gloss of a source language sentence, target language natives can uncover the latent, fully-fluent rendering of the translation. In this work we explore this intuition by breaking translation into a two step process: generating a rough gloss by means of a dictionary and then ‘translating’ the resulting pseudo-translation, or ‘Translationese’ into a fully fluent translation.

Learning to Optimize Halide with Tree Search and Random Programs


We present a new algorithm to automatically schedule Halide programs for high-performance image processing and deep learning. We significantly improve upon the performance of previous methods, which considered a limited subset of schedules.

Adaptive Attention Span in Transformers

Association for Computational Linguistics (ACL)

We propose a novel self-attention mechanism that can learn its optimal attention span. This allows us to extend significantly the maximum context size used in Transformer, while maintaining control over their memory footprint and computational time.
