Net 835-Gb/s/λ Carrier- and LO-Free 100-km Transmission Using Channel-Aware Phase Retrieval Reception

no code implementations10 Apr 2024 Hanzi Huang, Haoshuo Chen, Qian Hu, Di Che, Yetian Huang, Brian Stern, Nicolas K. Fontaine, Mikael Mazur, Lauren Dallachiesa, Roland Ryf, Zhengxuan Li, Yingxiong Song

We experimentally demonstrate the first carrier- and LO-free 800G/{\lambda} receiver enabling direct compatibility with standard coherent transmitters via phase retrieval, achieving net 835-Gb/s transmission over 100-km SMF and record 8. 27-b/s/Hz net optical spectral efficiency.

Toward Informal Language Processing: Knowledge of Slang in Large Language Models

no code implementations2 Apr 2024 Zhewei Sun, Qian Hu, Rahul Gupta, Richard Zemel, Yang Xu

Our work offers a comprehensive evaluation and a high-quality benchmark on English slang based on the OpenSubtitles corpus, serving both as a publicly accessible resource and a platform for applying tools for informal language processing.

Faithful Model Evaluation for Model-Based Metrics

no code implementations19 Dec 2023 Palash Goyal, Qian Hu, Rahul Gupta

Statistical significance testing is used in natural language processing (NLP) to determine whether the results of a study or experiment are likely to be due to chance or if they reflect a genuine relationship.

Evaluating Large Language Models on Controlled Generation Tasks

1 code implementation23 Oct 2023 Jiao Sun, Yufei Tian, Wangchunshu Zhou, Nan Xu, Qian Hu, Rahul Gupta, John Frederick Wieting, Nanyun Peng, Xuezhe Ma

While recent studies have looked into the abilities of large language models in various benchmark tasks, including question generation, reading comprehension, multilingual and etc, there have been few studies looking into the controllability of large language models on generation tasks.

FLIRT: Feedback Loop In-context Red Teaming

no code implementations8 Aug 2023 Ninareh Mehrabi, Palash Goyal, Christophe Dupuy, Qian Hu, Shalini Ghosh, Richard Zemel, Kai-Wei Chang, Aram Galstyan, Rahul Gupta

Here we propose an automatic red teaming framework that evaluates a given model and exposes its vulnerabilities against unsafe and inappropriate content generation.

Balancing the trade-off between cost and reliability for wireless sensor networks: a multi-objective optimized deployment method

1 code implementation19 Jul 2022 Long Chen, Yingying Xu, Fangyi Xu, Qian Hu, Zhenzhou Tang

In addition, this work fully considers the heterogeneity of SNs (i. e. differentiated sensing range and deployment cost) and three-dimensional (3-D) deployment scenarios.

Predicting vacant parking space availability zone-wisely: a graph based spatio-temporal prediction approach

no code implementations3 May 2022 Yajing Feng, Qian Hu, Zhenzhou Tang

Vacant parking space (VPS) prediction is one of the key issues of intelligent parking guidance systems.

OPP-Miner: Order-preserving sequential pattern mining

no code implementations9 Jan 2022 Youxi Wu, Qian Hu, Yan Li, Lei Guo, Xingquan Zhu, Xindong Wu

To discover patterns, existing methods often convert time series data into another form, such as nominal/symbolic format, to reduce dimensionality, which inevitably deviates the data values.

A Detector-oblivious Multi-arm Network for Keypoint Matching

1 code implementation2 Apr 2021 Xuelun Shen, Cheng Wang, Xin Li, Qian Hu, Jingyi Zhang

This paper presents a matching network to establish point correspondence between images.

Metric-Free Individual Fairness with Cooperative Contextual Bandits

no code implementations13 Nov 2020 Qian Hu, Huzefa Rangwala

Group fairness requires that different groups should be treated similarly which might be unfair to some individuals within a group.

Reliable Deep Grade Prediction with Uncertainty Estimation

no code implementations26 Feb 2019 Qian Hu, Huzefa Rangwala

Prior research on students' grade prediction include shallow linear models; however, students' learning is a highly complex process that involves the accumulation of knowledge across a sequence of courses that can not be sufficiently modeled by these linear models.
