Asking for Knowledge: Training RL Agents to Query External Knowledge Using Language

no code implementations12 May 2022 Iou-Jen Liu, Xingdi Yuan, Marc-Alexandre Côté, Pierre-Yves Oudeyer, Alexander G. Schwing

In order to study how agents can be taught to query external knowledge via language, we first introduce two new environments: the grid-world-based Q-BabyAI and the text-based Q-TextWorld.

Interactive Machine Comprehension with Dynamic Knowledge Graphs

1 code implementation EMNLP 2021 Xingdi Yuan

Interactive machine reading comprehension (iMRC) is machine comprehension tasks where knowledge sources are partially observable.

BUTLER: Building Understanding in TextWorld via Language for Embodied Reasoning

no code implementations ICLR 2021 Mohit Shridhar, Xingdi Yuan, Marc-Alexandre Cote, Yonatan Bisk, Adam Trischler, Matthew Hausknecht

ALFWorld enables the creation of a new BUTLER agent whose abstract knowledge, learned in TextWorld, corresponds directly to concrete, visually grounded actions.

An Empirical Study on Neural Keyphrase Generation

no code implementations NAACL 2021 Rui Meng, Xingdi Yuan, Tong Wang, Sanqiang Zhao, Adam Trischler, Daqing He

Recent years have seen a flourishing of neural keyphrase generation (KPG) works, including the release of several large-scale datasets and a host of new models to tackle them.

Graph Policy Network for Transferable Active Learning on Graphs

1 code implementation NeurIPS 2020 Shengding Hu, Zheng Xiong, Meng Qu, Xingdi Yuan, Marc-Alexandre Côté, Zhiyuan Liu, Jian Tang

Graph neural networks (GNNs) have been attracting increasing popularity due to their simplicity and effectiveness in a variety of fields.

Role-Wise Data Augmentation for Knowledge Distillation

1 code implementation ICLR 2020 Jie Fu, Xue Geng, Zhijian Duan, Bohan Zhuang, Xingdi Yuan, Adam Trischler, Jie Lin, Chris Pal, Hao Dong

To our knowledge, existing methods overlook the fact that although the student absorbs extra knowledge from the teacher, both models share the same input data -- and this data is the only medium by which the teacher's knowledge can be demonstrated.

Interactive Fiction Games: A Colossal Adventure

2 code implementations11 Sep 2019 Matthew Hausknecht, Prithviraj Ammanabrolu, Marc-Alexandre Côté, Xingdi Yuan

A hallmark of human intelligence is the ability to understand and communicate with language.

Does Order Matter? An Empirical Study on Generating Multiple Keyphrases as a Sequence

1 code implementation9 Sep 2019 Rui Meng, Xingdi Yuan, Tong Wang, Peter Brusilovsky, Adam Trischler, Daqing He

Recently, concatenating multiple keyphrases as a target sequence has been proposed as a new learning paradigm for keyphrase generation.

Interactive Machine Comprehension with Information Seeking Agents

1 code implementation ACL 2020 Xingdi Yuan, Jie Fu, Marc-Alexandre Cote, Yi Tay, Christopher Pal, Adam Trischler

Existing machine reading comprehension (MRC) models do not scale effectively to real-world applications like web-level information retrieval and question answering (QA).

Towards Solving Text-based Games by Producing Adaptive Action Spaces

2 code implementations3 Dec 2018 Ruo Yu Tao, Marc-Alexandre Côté, Xingdi Yuan, Layla El Asri

To solve a text-based game, an agent needs to formulate valid text commands for a given context and find the ones that lead to success.

Building Dynamic Knowledge Graphs from Text using Machine Reading Comprehension

no code implementations ICLR 2019 Rajarshi Das, Tsendsuren Munkhdalai, Xingdi Yuan, Adam Trischler, Andrew McCallum

We harness and extend a recently proposed machine reading comprehension (MRC) model to query for entity states, since these states are generally communicated in spans of text and MRC models perform well in extracting entity-centric spans.

Counting to Explore and Generalize in Text-based Games

2 code implementations29 Jun 2018 Xingdi Yuan, Marc-Alexandre Côté, Alessandro Sordoni, Romain Laroche, Remi Tachet des Combes, Matthew Hausknecht, Adam Trischler

We propose a recurrent RL agent with an episodic exploration mechanism that helps discovering good policies in text-based game environments.

Rapid Adaptation with Conditionally Shifted Neurons

no code implementations ICML 2018 Tsendsuren Munkhdalai, Xingdi Yuan, Soroush Mehri, Adam Trischler

We describe a mechanism by which artificial neural networks can learn rapid adaptation - the ability to adapt on the fly, with little data, to new tasks - that we call conditionally shifted neurons.

A Joint Model for Question Answering and Question Generation

no code implementations5 Jun 2017 Tong Wang, Xingdi Yuan, Adam Trischler

We propose a generative machine comprehension model that learns jointly to ask and answer questions based on documents.

A Parallel-Hierarchical Model for Machine Comprehension on Sparse Data

1 code implementation ACL 2016 Adam Trischler, Zheng Ye, Xingdi Yuan, Jing He, Phillip Bachman, Kaheer Suleman

The parallel hierarchy enables our model to compare the passage, question, and answer from a variety of trainable perspectives, as opposed to using a manually designed, rigid feature set.
