Automated Generation of Multiple-Choice Cloze Questions for Assessing English Vocabulary Using GPT-turbo 3.5

no code implementations4 Mar 2024 Qiao Wang, Ralph Rose, Naho Orita, Ayaka Sugawara

The VocaTT (vocabulary teaching and training) engine is written in Python and comprises three basic steps: pre-processing target word lists, generating sentences and candidate word options using GPT, and finally selecting suitable word options.

Assessing the Efficacy of Grammar Error Correction: A Human Evaluation Approach in the Japanese Context

no code implementations28 Feb 2024 Qiao Wang, Zheng Yuan

In this study, we evaluated the performance of the state-of-the-art sequence tagging grammar error detection and correction model (SeqTagger) using Japanese university students' writing samples.

A Unified Framework for Fair Spectral Clustering With Effective Graph Learning

no code implementations23 Nov 2023 Xiang Zhang, Qiao Wang

Traditional fair spectral clustering (FSC) methods consist of two consecutive stages, i. e., performing fair spectral embedding on a given graph and conducting $k$means to obtain discrete cluster labels.

Equal Incremental Cost-Based Optimization Method to Enhance Efficiency for IPOP-Type Converters

no code implementations12 Nov 2023 Hanfeng Cai, Haiyang Liu, Heyang Sun, Qiao Wang

This paper addresses the issue of enhancing the efficiency of a multiple module system connected in parallel during operation and proposes an algorithm based on equal incremental cost for dynamic load allocation.

Graph Learning Across Data Silos

no code implementations17 Jan 2023 Xiang Zhang, Qiao Wang

We consider the problem of inferring graph topology from smooth graph signals in a novel but practical scenario where data are located in distributed clients and prohibited from leaving local clients due to factors such as privacy concerns.

Yuille-Poggio's Flow and Global Minimizer of polynomials through convexification by Heat Evolution

no code implementations1 Jan 2023 Qiao Wang

On the other hand, we propose the "seesaw" polynomials $p(x|s)$ and we find a seesaw differential equation $\frac{\partial p(x|s)}{\, ds}=-\frac{1}{p''(x)}$ to characterize the evolution of global minimizer $x^*(s)$ of $p(x|s)$ while varying $s$.

Time-varying Graph Learning Under Structured Temporal Priors

no code implementations11 Oct 2021 Xiang Zhang, Qiao Wang

Different from many existing chain structure based methods in which the priors like temporal homogeneity can only describe the variations of two consecutive graphs, we propose a structure named \emph{temporal graph} to characterize the underlying real temporal relations.

A Semantic Indexing Structure for Image Retrieval

no code implementations14 Sep 2021 Ying Wang, Tingzhen Liu, Zepeng Bu, YuHui Huang, Lizhong Gao, Qiao Wang

In large-scale image retrieval, many indexing methods have been proposed to narrow down the searching scope of retrieval.

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.

Virtual Worlds as Proxy for Multi-Object Tracking Analysis

no code implementations CVPR 2016 Adrien Gaidon, Qiao Wang, Yohann Cabon, Eleonora Vig

We provide quantitative experimental evidence suggesting that (i) modern deep learning algorithms pre-trained on real data behave similarly in real and virtual worlds, and (ii) pre-training on virtual data improves performance.
