Macroscopic auxiliary asymptotic preserving neural networks for the linear radiative transfer equations

no code implementations4 Mar 2024 Hongyan Li, Song Jiang, Wenjun Sun, Liwei Xu, Guanyu Zhou

We develop a Macroscopic Auxiliary Asymptotic-Preserving Neural Network (MA-APNN) method to solve the time-dependent linear radiative transfer equations (LRTEs), which have a multi-scale nature and high dimensionality.

Curriculum Design Helps Spiking Neural Networks to Classify Time Series

no code implementations26 Dec 2023 Chenxi Sun, Hongyan Li, Moxian Song, Derun Can, Shenda Hong

Spiking Neural Networks (SNNs) have a greater potential for modeling time series data than Artificial Neural Networks (ANNs), due to their inherent neuron dynamics and low energy consumption.

Generative Adversarial Network for Abstractive Text Summarization

1 code implementation26 Nov 2017 Linqing Liu, Yao Lu, Min Yang, Qiang Qu, Jia Zhu, Hongyan Li

In this paper, we propose an adversarial process for abstractive text summarization, in which we simultaneously train a generative model G and a discriminative model D. In particular, we build the generator G as an agent of reinforcement learning, which takes the raw text as input and predicts the abstractive summarization.
