JARVIS: A Neuro-Symbolic Commonsense Reasoning Framework for Conversational Embodied Agents

no code implementations28 Aug 2022 Kaizhi Zheng, Kaiwen Zhou, Jing Gu, Yue Fan, Jialu Wang, Zonglin Di, Xuehai He, Xin Eric Wang

Building a conversational embodied agent to execute real-life tasks has been a long-standing yet quite challenging research goal, as it requires effective human-agent communication, multi-modal understanding, long-range sequential decision making, etc.

Understanding Instance-Level Impact of Fairness Constraints

1 code implementation30 Jun 2022 Jialu Wang, Xin Eric Wang, Yang Liu

A variety of fairness constraints have been proposed in the literature to mitigate group-level statistical bias.


Fairness Transferability Subject to Bounded Distribution Shift

1 code implementation31 May 2022 Yatong Chen, Reilly Raab, Jialu Wang, Yang Liu

Given an algorithmic predictor that is "fair" on some source distribution, will it still be fair on an unknown target distribution that differs from the source within some bound?

Beyond Images: Label Noise Transition Matrix Estimation for Tasks with Lower-Quality Features

2 code implementations2 Feb 2022 Zhaowei Zhu, Jialu Wang, Yang Liu

We observe that tasks with lower-quality features fail to meet the anchor-point or clusterability condition, due to the coexistence of both uninformative and informative representations.

Are Gender-Neutral Queries Really Gender-Neutral? Mitigating Gender Bias in Image Search

1 code implementation EMNLP 2021 Jialu Wang, Yang Liu, Xin Eric Wang

Internet search affects people's cognition of the world, so mitigating biases in search results and learning fair models is imperative for social good.

Can Less be More? When Increasing-to-Balancing Label Noise Rates Considered Beneficial

1 code implementation NeurIPS 2021 Yang Liu, Jialu Wang

In this paper, we first quantify the trade-offs introduced by increasing a certain group of instances' label noise rate w. r. t.

Assessing Multilingual Fairness in Pre-trained Multimodal Representations

no code implementations Findings (ACL) 2022 Jialu Wang, Yang Liu, Xin Eric Wang

To answer these questions, we view language as the fairness recipient and introduce two new fairness notions, multilingual individual fairness and multilingual group fairness, for pre-trained multimodal models.


Linear Classifiers that Encourage Constructive Adaptation

no code implementations31 Oct 2020 Yatong Chen, Jialu Wang, Yang Liu

Machine learning systems are often used in settings where individuals adapt their features to obtain a desired outcome.

Fair Classification with Group-Dependent Label Noise

1 code implementation31 Oct 2020 Jialu Wang, Yang Liu, Caleb Levy

We begin by presenting analytical results which show that naively imposing parity constraints on demographic disparity measures, without accounting for heterogeneous and group-dependent error rates, can decrease both the accuracy and the fairness of the resulting classifier.

AceKG: A Large-scale Knowledge Graph for Academic Data Mining

no code implementations23 Jul 2018 Ruijie Wang, Yuchen Yan, Jialu Wang, Yuting Jia, Ye Zhang, Wei-Nan Zhang, Xinbing Wang

Most existing knowledge graphs (KGs) in academic domains suffer from problems of insufficient multi-relational information, name ambiguity and improper data format for large-scale machine processing.
