Global existences and asymptotic behavior for semilinear heat equation

no code implementations28 Dec 2020 Avy Soffer, Yifei Wu, Xiaohua Yao

In this paper, we consider the global Cauchy problem for the $L^2$-critical semilinear heat equations $ \partial_t h=\Delta h\pm |h|^{\frac4d}h, $ with $h(0, x)=h_0$, where $h$ is an unknown real function defined on $ \R^+\times\R^d$.

A Convolutional Neural Network for Aspect Sentiment Classification

no code implementations4 Jul 2018 Yongping Xing, Chuangbai Xiao, Yifei Wu, Ziming Ding

If the aspect is picture quality, then the expected sentiment polarity is 'positive', if the battery life aspect is considered, then the sentiment polarity should be 'negative'; therefore, aspect is important to consider when we explore aspect sentiment in the sentence.
