WordDecipher: Enhancing Digital Workspace Communication with Explainable AI for Non-native English Speakers

no code implementations10 Apr 2024 Yuexi Chen, Zhicheng Liu

Non-native English speakers (NNES) face challenges in digital workspace communication (e. g., emails, Slack messages), often inadvertently translating expressions from their native languages, which can lead to awkward or incorrect usage.

DiJiang: Efficient Large Language Models through Compact Kernelization

1 code implementation29 Mar 2024 Hanting Chen, Zhicheng Liu, Xutao Wang, Yuchuan Tian, Yunhe Wang

In an effort to reduce the computational load of Transformers, research on linear attention has gained significant momentum.

TutoAI: A Cross-domain Framework for AI-assisted Mixed-media Tutorial Creation on Physical Tasks

no code implementations12 Mar 2024 Yuexi Chen, Vlad I. Morariu, Anh Truong, Zhicheng Liu

Mixed-media tutorials, which integrate videos, images, text, and diagrams to teach procedural skills, offer more browsable alternatives than timeline-based videos.

HealMe: Harnessing Cognitive Reframing in Large Language Models for Psychotherapy

no code implementations26 Feb 2024 Mengxi Xiao, Qianqian Xie, Ziyan Kuang, Zhicheng Liu, Kailai Yang, Min Peng, Weiguang Han, Jimin Huang

Large Language Models (LLMs) can play a vital role in psychotherapy by adeptly handling the crucial task of cognitive reframing and overcoming challenges such as shame, distrust, therapist skill variability, and resource scarcity.

PanGu-$π$: Enhancing Language Model Architectures via Nonlinearity Compensation

no code implementations27 Dec 2023 Yunhe Wang, Hanting Chen, Yehui Tang, Tianyu Guo, Kai Han, Ying Nie, Xutao Wang, Hailin Hu, Zheyuan Bai, Yun Wang, Fangcheng Liu, Zhicheng Liu, Jianyuan Guo, Sinan Zeng, Yinchen Zhang, Qinghua Xu, Qun Liu, Jun Yao, Chao Xu, DaCheng Tao

We then demonstrate that the proposed approach is significantly effective for enhancing the model nonlinearity through carefully designed ablations; thus, we present a new efficient model architecture for establishing modern, namely, PanGu-$\pi$.

Mystique: Deconstructing SVG Charts for Layout Reuse

no code implementations25 Jul 2023 Chen Chen, Bongshin Lee, Yunhai Wang, Yunjeong Chang, Zhicheng Liu

To facilitate the reuse of existing charts, previous research has examined how to obtain a semantic understanding of a chart by deconstructing its visual representation into reusable components, such as encodings.

Complexity-aware Large Scale Origin-Destination Network Generation via Diffusion Model

no code implementations8 Jun 2023 Can Rong, Jingtao Ding, Zhicheng Liu, Yong Li

The Origin-Destination~(OD) networks provide an estimation of the flow of people from every region to others in the city, which is an important research topic in transportation, urban simulation, etc.

Improving speech translation by fusing speech and text

no code implementations23 May 2023 Wenbiao Yin, Zhicheng Liu, Chengqi Zhao, Tao Wang, Jian Tong, Rong Ye

To tackle these gaps, we propose \textbf{F}use-\textbf{S}peech-\textbf{T}ext (\textbf{FST}), a cross-modal model which supports three distinct input modalities for translation: speech, text, and fused speech-text.

Transportation Scenario Planning with Graph Neural Networks

no code implementations25 Oct 2021 Ana Alice Peregrino, Soham Pradhan, Zhicheng Liu, Nivan Ferreira, Fabio Miranda

Providing efficient human mobility services and infrastructure is one of the major concerns of most mid-sized to large cities around the world.

The Volctrans Neural Speech Translation System for IWSLT 2021

1 code implementation ACL (IWSLT) 2021 Chengqi Zhao, Zhicheng Liu, Jian Tong, Tao Wang, Mingxuan Wang, Rong Ye, Qianqian Dong, Jun Cao, Lei LI

For offline speech translation, our best end-to-end model achieves 8. 1 BLEU improvements over the benchmark on the MuST-C test set and is even approaching the results of a strong cascade solution.

Robust Graph Learning Under Wasserstein Uncertainty

no code implementations10 May 2021 Xiang Zhang, Yinfei Xu, Qinghe Liu, Zhicheng Liu, Jian Lu, Qiao Wang

To this end, we propose a graph learning framework using Wasserstein distributionally robust optimization (WDRO) which handles uncertainty in data by defining an uncertainty set on distributions of the observed data.

Learning Geo-Contextual Embeddings for Commuting Flow Prediction

1 code implementation4 May 2020 Zhicheng Liu, Fabio Miranda, Weiting Xiong, Junyan Yang, Qiao Wang, Claudio T. Silva

Then, an attention mechanism is proposed based on the framework of graph attention network (GAT) to capture the spatial correlations and encode geographic contextual information to embedding space.
