Automated Identification and Segmentation of Hi Sources in CRAFTS Using Deep Learning Method

1 code implementation29 Mar 2024 Zihao Song, Huaxi Chen, Donghui Quan, Di Li, Yinghui Zheng, Shulei Ni, Yunchuan Chen, Yun Zheng

We introduce a machine learning-based method for extracting HI sources from 3D spectral data, and construct a dedicated dataset of HI sources from CRAFTS.

Deep Learning for Day Forecasts from Sparse Observations

no code implementations6 Jun 2023 Marcin Andrychowicz, Lasse Espeholt, Di Li, Samier Merchant, Alexander Merose, Fred Zyda, Shreya Agrawal, Nal Kalchbrenner

The ability of neural models to make a prediction in less than a second once the data is available and to do so with very high temporal and spatial resolution, and the ability to learn directly from atmospheric observations, are just some of these models' unique advantages.

GAS: A Gaussian Mixture Distribution-Based Adaptive Sampling Method for PINNs

no code implementations28 Mar 2023 Yuling Jiao, Di Li, Xiliang Lu, Jerry Zhijian Yang, Cheng Yuan

With the recent study of deep learning in scientific computation, the Physics-Informed Neural Networks (PINNs) method has drawn widespread attention for solving Partial Differential Equations (PDEs).

LGN-Net: Local-Global Normality Network for Video Anomaly Detection

1 code implementation14 Nov 2022 Mengyang Zhao, Xinhua Zeng, Yang Liu, Jing Liu, Di Li, Xing Hu, Chengxin Pang

Existing unsupervised VAD methods tend to learn normality from training sets consisting of only normal videos and regard instances deviating from such normality as anomalies.

Carbon-chain molecule survey toward four low-mass molecular outflow sources

no code implementations11 Mar 2021 C. Zhang, Y. Wu, X. -C. Liu, Mengyao Tang, Di Li, Jarken Esimbek, S. -L. Qin

Hydrocarbons and HC$_3$N were detected in all the sources, except for L1598, which had a marginal detection of C$_4$H and a non-detection of HC$_3$N (J=2--1).

The first evidence for three-dimensional spin-velocity alignment in pulsars

no code implementations2 Mar 2021 Jumei Yao, Weiwei Zhu, Richard N. Manchester, William A. Coles, Di Li, Na Wang, Michael Kramer, Daniel R. Stinebring, Yi Feng, Wenming Yan, Chenchen Miao, Mao Yuan, Pei Wang, Jiguang Lu

Observations have shown a strong tendency for alignment of the pulsar space velocity and spin axis in young pulsars but, up to now, these comparisons have been restricted to two dimensions.

From haloes to galaxies -- II. The fundamental relations in star formation and quenching

no code implementations7 Oct 2020 Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci, Emanuele Daddi, Yu Gao, Roberto Maiolino, Chengpeng Zhang, Qiusheng Gu, Di Li, Simon J. Lilly, Feng Yuan

We show the integrated $M_{\rm H_2}$-SFR, SFR-$M_*$ and $M_{\rm H_2}$-$M_*$ relation can be simply transformed from the $\mu$-sSFR, SFE-$\mu$ and SFE-sSFR relation, respectively.

Universal Rules for Fooling Deep Neural Networks based Text Classification

no code implementations22 Jan 2019 Di Li, Danilo Vasconcellos Vargas, Sakurai Kouichi

Here, we go beyond attacks to investigate, for the first time, universal rules, i. e., rules that are sample agnostic and therefore could turn any text sample in an adversarial one.
