Learning Transferable Feature Representations Using Neural Networks (P19-1)
Copied to clipboard
| Challenge: | Traditional domain adaptation algorithms learn common representations which suffer from transfer loss when the source specific characteristics detract their ability to represent the target data. |
| Approach: | They propose to segregate source specific representation from the common representation and use it to learn a two-part representation which captures source specific characteristics while the second part captures the truly common representation. |
| Outcome: | The proposed representation outperforms existing learning algorithms on the source learning as well as cross-domain tasks on multiple datasets. |
Identifying Transferable Information Across Domains for Cross-domain Sentiment Classification (P18-1)
Copied to clipboard
| Challenge: | Cross-domain sentiment classification is challenging due to polarity orientation and significance differences . supervised learning algorithms have to be re-trained on every new domain . |
| Approach: | They propose that words that do not change their polarity and significance represent transferable information across domains for cross-domain sentiment classification. |
| Outcome: | The proposed method improves cross-domain sentiment classification performance by identifying polarity-preserving significant words across domains. |
