Papers with bias problem
Kernel-Whitening: Overcome Dataset Bias with Isotropic Sentence Embedding (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to reduce dataset bias rely on spurious correlations and obstruct valid feature information while mitigating bias. |
| Approach: | They propose a representation normalization method which disentangles correlations between features of encoded sentences and a kernel approximation method which provides isotropic data distribution. |
| Outcome: | The proposed method eliminates the bias problem by providing isotropic data distribution while maintaining in-distribution accuracy. |
A Multi-modal Debiasing Model with Dynamical Constraint for Robust Visual Question Answering (2023.findings-acl)
Copied to clipboard
| Challenge: | Recent studies have shown that many well-developed Visual Question Answering systems suffer from bias problem. |
| Approach: | They propose a way to mitigate bias problem by subtracting bias score from standard VQA base score. |
| Outcome: | The proposed method improves on the VQA v2.0 and VQA-CP V2,0 datasets. |
Investigating Dynamic Routing in Tree-Structured LSTM for Sentiment Analysis (D19-1)
Copied to clipboard
| Challenge: | Existing deep neural network models such as LSTM and tree-LSTM have a bias problem where the words in the tail of a sentence are more heavily emphasized than those in the header. |
| Approach: | They propose a capsule tree-LSTM model that uses dynamic routing to build sentence representations by assigning different weights to nodes according to their contributions to prediction. |
| Outcome: | The proposed model improves on the Stanford Sentiment Treebank and EmoBank datasets. |
Regularized Context Gates on Transformer for Machine Translation (2020.acl-main)
Copied to clipboard
| Challenge: | Context gates are effective to control the contributions from the source and target contexts in the recurrent neural network (RNN) based neural machine translation. |
| Approach: | They propose a method to identify source and target contexts and introduce a gate mechanism to control the contributions from source and targets in the advanced Transformer architecture. |
| Outcome: | The proposed model achieves an averaged gain of 1.0 BLEU score over a strong transformer baseline. |
