Multi-Teacher Multi-Objective Meta-Learning for Zero-Shot Hyperspectral Band Selection

no code implementations12 Jun 2024 Jie Feng, Xiaojian Zhong, Di Li, Weisheng Dong, Ronghua Shang, Licheng Jiao

However, most existing deep learning-based methods are aimed at dealing with a specific band selection dataset, and need to retrain parameters for new datasets, which significantly limits their generalizability. To address this issue, a novel multi-teacher multi-objective meta-learning network (M$^3$BS) is proposed for zero-shot hyperspectral band selection.

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

With the advancement of observational technology, especially with the advent of large-scale telescope projects such as FAST and SKA, the significant increase in data volume presents new challenges for the efficiency and accuracy of data processing. To address this challenge, in this study, we present a machine learning-based method for extracting \hi\ sources from the three-dimensional (3D) spectral data obtained from the Commensal Radio Astronomy FAST Survey (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.

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.

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.
