Self-Retrieval: Building an Information Retrieval System with One Large Language Model

no code implementations23 Feb 2024 Qiaoyu Tang, Jiawei Chen, Bowen Yu, Yaojie Lu, Cheng Fu, Haiyang Yu, Hongyu Lin, Fei Huang, Ben He, Xianpei Han, Le Sun, Yongbin Li

The rise of large language models (LLMs) has transformed the role of information retrieval (IR) systems in the way to humans accessing information.

Unified Language Representation for Question Answering over Text, Tables, and Images

no code implementations29 Jun 2023 Bowen Yu, Cheng Fu, Haiyang Yu, Fei Huang, Yongbin Li

When trying to answer complex questions, people often rely on multiple sources of information, such as visual, textual, and tabular data.

Coarse-to-Fine Knowledge Selection for Document Grounded Dialogs

no code implementations23 Feb 2023 Yeqin Zhang, Haomin Fu, Cheng Fu, Haiyang Yu, Yongbin Li, Cam-Tu Nguyen

Specifically, the former efficiently finds relevant passages in a retrieval-and-reranking process, whereas the latter effectively extracts finer-grain spans within those passages to incorporate into a parametric answer generation model (BART, T5).

Metropolitan Segment Traffic Speeds from Massive Floating Car Data in 10 Cities

1 code implementation17 Feb 2023 Moritz Neun, Christian Eichenberger, Yanan Xin, Cheng Fu, Nina Wiedemann, Henry Martin, Martin Tomko, Lukas Ambühl, Luca Hermes, Michael Kopp

Traffic analysis is crucial for urban operations and planning, while the availability of dense urban traffic data beyond loop detectors is still scarce.

TripLe: Revisiting Pretrained Model Reuse and Progressive Learning for Efficient Vision Transformer Scaling and Searching

no code implementations ICCV 2023 Cheng Fu, Hanxian Huang, Zixuan Jiang, Yun Ni, Lifeng Nai, Gang Wu, Liqun Cheng, Yanqi Zhou, Sheng Li, Andrew Li, Jishen Zhao

One promising way to accelerate transformer training is to reuse small pretrained models to initialize the transformer, as their existing representation power facilitates faster model convergence.

Layout-Aware Information Extraction for Document-Grounded Dialogue: Dataset, Method and Demonstration

no code implementations14 Jul 2022 Zhenyu Zhang, Bowen Yu, Haiyang Yu, Tingwen Liu, Cheng Fu, Jingyang Li, Chengguang Tang, Jian Sun, Yongbin Li

In this paper, we propose a Layout-aware document-level Information Extraction dataset, LIE, to facilitate the study of extracting both structural and semantic knowledge from visually rich documents (VRDs), so as to generate accurate responses in dialogue systems.

Bridging the Gap between Reality and Ideality of Entity Matching: A Revisiting and Benchmark Re-Construction

no code implementations12 May 2022 Tianshu Wang, Hongyu Lin, Cheng Fu, Xianpei Han, Le Sun, Feiyu Xiong, Hui Chen, Minlong Lu, Xiuwen Zhu

Experimental results demonstrate that the assumptions made in the previous benchmark construction process are not coincidental with the open environment, which conceal the main challenges of the task and therefore significantly overestimate the current progress of entity matching.

ProFlip: Targeted Trojan Attack With Progressive Bit Flips

no code implementations ICCV 2021 Huili Chen, Cheng Fu, Jishen Zhao, Farinaz Koushanfar

In this work, we present ProFlip, the first targeted Trojan attack framework that can divert the prediction of the DNN to the target class by progressively identifying and flipping a small set of bits in model parameters.

Towards Measuring Place Function Similarity at Fine Spatial Granularity with Trajectory Embedding

no code implementations31 Oct 2020 Cheng Fu, Robert Weibel

The embedding similarity was previously proposed as a new metric for measuring the similarity of place functions.

Dimensionality Reduction

A Neural-based Program Decompiler

no code implementations28 Jun 2019 Cheng Fu, Huili Chen, Haolan Liu, Xinyun Chen, Yuandong Tian, Farinaz Koushanfar, Jishen Zhao

Reverse engineering of binary executables is a critical problem in the computer security domain.

Towards Fast and Energy-Efficient Binarized Neural Network Inference on FPGA

no code implementations4 Oct 2018 Cheng Fu, Shilin Zhu, Hao Su, Ching-En Lee, Jishen Zhao

Thus there does exist redundancy that can be exploited to further reduce the amount of on-chip computations.
