Papers with feature projection
A Unified Neural Network Model for Readability Assessment with Feature Projection and Length-Balanced Loss (2022.emnlp-main)
Copied to clipboard
| Challenge: | Traditional readability assessment models employ hundreds of linguistic features, but it is less explored for readability assessments. |
| Approach: | They propose a BERT-based model with feature projection and length-balanced loss to determine the difficulty level of a given text. |
| Outcome: | The proposed model achieves significant improvements over baseline models on three English benchmark datasets and one Chinese dataset. |
Feature Projection for Improved Text Classification (2020.acl-main)
Copied to clipboard
| Challenge: | In sentiment classification, there are some good features that are indicative of class labels, but there are also many common features that do not discriminate for classification. |
| Approach: | They propose to project existing features into the orthogonal space of the common features and make them more discriminative for classification. |
| Outcome: | The proposed method improves CNN, RNN, Transformer, and Bert based text classification and obtains markedly better results. |
