Erdem Bıyık, Malayandi Palan, Nicholas C. Landolfi, Dylan P. Losey, Dorsa Sadigh
2019 arXiv   pre-print
Simulations and a user study show our method not only produces easy questions, but also ultimately results in faster reward learning.  ...  Robots can learn the right reward function by querying a human expert.  ...  Toyota Research Institute (TRI) provided funds to assist the authors with their research but this article solely reflects the opinions and conclusions of its authors and not TRI or any other Toyota entity  ...

Here's What I've Learned: Asking Questions that Reveal Reward Learning [article]

Soheil Habibian, Ananth Jonnavittula, Dylan P. Losey
2021 arXiv   pre-print
Robots can learn from humans by asking questions. In these questions the robot demonstrates a few different behaviors and asks the human for their favorite.  ...  We develop and test a model that robots can leverage to relate the questions they ask to the information these questions reveal.  ...  USER STUDIES We conducted two in-person user studies to compare our approach to a state-of-the-art active learning baseline.  ...

Unified Questioner Transformer for Descriptive Question Generation in Goal-Oriented Visual Dialogue [article]

Shoya Matsumori, Kosuke Shingyouchi, Yuki Abe, Yosuke Fukuchi, Komei Sugiura, Michita Imai
2021 arXiv   pre-print
In addition, we build a goal-oriented visual dialogue task called CLEVR Ask. It synthesizes complex scenes that require the Questioner to generate descriptive questions.  ...  In particular, goal-oriented visual dialogue, where the aim of the agent is to seek information by asking questions during a turn-taking dialogue, has been gaining scholarly attention recently.  ...  For example, in simple scenes, where each object has different attributes and thus is easy to distinguish, the Questioner only needs to ask category-based questions such as "Is it a car?".  ...

It is AI's Turn to Ask Humans a Question: Question-Answer Pair Generation for Children's Story Books [article]

Bingsheng Yao, Dakuo Wang, Tongshuang Wu, Zheng Zhang, Toby Jia-Jun Li, Mo Yu, Ying Xu
2022 arXiv   pre-print
Existing question answering (QA) techniques are created mainly to answer questions asked by humans.  ...  But in educational applications, teachers often need to decide what questions they should ask, in order to help students to improve their narrative understanding capabilities.  ...  In fact, a couple of recent works use this dataset and train a network by combining a QG module and a QA module with a reinforcement learning approach (Tang et al., 2017) .  ...

Complex Knowledge Base Question Answering: A Survey [article]

Yunshi Lan, Gaole He, Jinhao Jiang, Jing Jiang, Wayne Xin Zhao, Ji-Rong Wen
2022 arXiv   pre-print
Knowledge base question answering (KBQA) aims to answer a question over a knowledge base (KB). Early studies mainly focused on answering simple questions over KBs and achieved great success.  ...  Therefore, in recent years, researchers propose a large number of novel methods, which looked into the challenges of answering complex questions.  ...  As users typically ask followup questions to explore a topic, deployed models are supposed to handle KBQA task in a conversational manner.  ...

Evaluation and improvement of student's question-posing ability in a web-based learning environment

Yu-Feng Lan, Pin-Chuan Lin
2011 Australasian Journal of Educational Technology  
To remedy this problem, the present study developed a system of integrating a reward mechanism into assessment activities, to measure the question-posing ability of individual students in a web-based learning  ...  However, this learning approach has some difficulties, one being the lack of a practical approach to assist teachers in evaluating the question-posing ability of all learners.  ...  The problem might be improved by providing a more user friendly interface and more rewards as incentives.  ...

We have devised a question-answer card interface to allow the elderly to participate in micro-tasks with minimal ICT skills and learning efforts.  ...  The primary target users involve senior citizens who have ICT devices such as smartphones or PCs but who do not actively use such technologies, who appear to be the majority of the senior population, at  ...  For the question asking about the compensation, the majority of the senior participants were less concerned about the rewards. The young participants tended to want 5 to 10 yen per card.  ...
