How do you remove bias from a data set?
Sample bias can be reduced or eliminated by:
- Training your model on both daytime and nighttime.
- Covering all the cases you expect your model to be exposed to. This can be done by examining the domain of each feature and make sure we have balanced evenly-distributed data covering all of it.
How can data analysis reduce bias?
There are ways, however, to try to maintain objectivity and avoid bias with qualitative data analysis:
- Use multiple people to code the data.
- Have participants review your results.
- Verify with more data sources.
- Check for alternative explanations.
- Review findings with peers.
Are there any tools to detect bias in data?
Recently, researchers at Princeton University developed a tool that identifies potential biases in image datasets that are used to train AI systems such as computer vision models. The open-source tool called REVISE can automatically uncover potential bias in visual datasets.
How to eliminate sample bias in a machine?

What’s the best way to mitigate visual bias?
The findings by researchers at the Princeton Visual AI Lab is a more effective way to mitigate bias which was suggested by them earlier. REVISE or REvealing VIsual biaSEs use statistical methods to study the dataset and identify potential bias across three dimensions — object-based, gender-based and geography-based.
How does revise or reveal visual bias work?
REVISE or REvealing VIsual biaSEs use statistical methods to study the dataset and identify potential bias across three dimensions — object-based, gender-based and geography-based. As the researchers mentioned, it works by filtering and balancing a dataset’s images in a way that requires more direction from the user.
