Inherent limitations of LLMs regarding spatial information

1 code implementation5 Dec 2023 He Yan, Xinyao Hu, Xiangpeng Wan, Chengyu Huang, Kai Zou, Shiqi Xu

Despite the significant advancements in natural language processing capabilities demonstrated by large language models such as ChatGPT, their proficiency in comprehending and processing spatial information, especially within the domains of 2D and 3D route planning, remains notably underdeveloped.

Nonlinear Multi-Carrier System with Signal Clipping: Measurement, Analysis, and Optimization

no code implementations1 Oct 2023 Yuyang Du, Liang Hao, Yiming Lei, Qun Yang, Shiqi Xu

With the derivations, we investigate the optimal system setting to achieve the SER lower bound in a practical OFDM system that considers both PA nonlinearity and clipping distortion.

Tensorial tomographic differential phase-contrast microscopy

no code implementations25 Apr 2022 Shiqi Xu, Xiang Dai, Xi Yang, Kevin C. Zhou, Kanghyun Kim, Vinayak Pathak, Carolyn Glass, Roarke Horstmeyer

We report Tensorial Tomographic Differential Phase-Contrast microscopy (T2DPC), a quantitative label-free tomographic imaging method for simultaneous measurement of phase and anisotropy.

Increasing a microscope's effective field of view via overlapped imaging and machine learning

no code implementations10 Oct 2021 Xing Yao, Vinayak Pathak, Haoran Xi, Amey Chaware, Colin Cooke, Kanghyun Kim, Shiqi Xu, Yuting Li, Timothy Dunn, Pavan Chandra Konda, Kevin C. Zhou, Roarke Horstmeyer

This work demonstrates a multi-lens microscopic imaging system that overlaps multiple independent fields of view on a single sensor for high-efficiency automated specimen analysis.

Text Augmentation in a Multi-Task View

no code implementations EACL 2021 Jason Wei, Chengyu Huang, Shiqi Xu, Soroush Vosoughi

Traditional data augmentation aims to increase the coverage of the input distribution by generating augmented examples that strongly resemble original samples in an online fashion where augmented examples dominate training.

Regularized Fourier Ptychography using an Online Plug-and-Play Algorithm

no code implementations31 Oct 2018 Yu Sun, Shiqi Xu, Yunzhe Li, Lei Tian, Brendt Wohlberg, Ulugbek S. Kamilov

The plug-and-play priors (PnP) framework has been recently shown to achieve state-of-the-art results in regularized image reconstruction by leveraging a sophisticated denoiser within an iterative algorithm.
