基于变分自编码器的情感回归半监督领域适应方法

A Semi-supervised Domain Adaptation Method of Sentiment Regression on Variational Autoencoder

提出一个新的情感回归半监督领域适应方法.首先使用长短期记忆网络(long short-term memory,LSTM)实现回归模型,其次使用变分自编码器(variational autoencoder,VAE)实现生成模型,最后联合学习LSTM回归模型和VAE生成模型,实现基于变分自编码器的情感回归半监督领域适应模型.实验结果表明,所提出的基于变分自编码器的情感回归半监督领域适应方法较其他基准方法能有效提高实验性能.

A novel approach was proposed for semi-supervised domain adaptation of sentiment regression,namely VAE-R. In VAE-R model,a long short-term memory( LSTM) network was employed to achieve a regression model,and then a generation model based on variational autoencoder( VAE). In the learning process,the LSTM regression model and the VAE generation model were jointly learned. Empirical studies had demonstrated the effectiveness of the proposed approach in the semi-supervised domain adaptation.
