Infosys Certified Generative AI Professional: What Techniques Are Used to Reduce Bias in Large Language Models?

Large language models can contain biases from their training data. Learn about the careful data curation and debiasing techniques used by AI researchers to mitigate bias and create more neutral models.

Question

The process of reducing biases in large language models involves

A. Eliminating all potential sources of bias
B. Limiting the amount of training data
C. Fine-tuning on more biased datasets
D. Careful curation and debiasing techniques

Answer

D. Careful curation and debiasing techniques

Explanation

Reducing bias in large language models is an important challenge in AI development. While it is virtually impossible to completely eliminate all potential sources of bias, AI researchers employ a combination of careful data curation and debiasing techniques to significantly reduce bias:

Data Curation: Training datasets are carefully reviewed to identify and remove overtly biased content where possible. Data may also be balanced to better represent different groups.

Debiasing Techniques: Various algorithms can be applied during training or post-processing to reduce learned biases. For example, adversarial debiasing adds a discriminator to identify bias during training. Word embedding debiasing adjusts vector spaces to remove stereotypical associations.

The goal is not to limit the training data, but to be selective about its content. Fine-tuning on datasets with more bias would be counterproductive. Through thoughtful data selection and debiasing methods, language models can be made more neutral while still benefiting from large datasets that give them broad knowledge and capabilities. However, some bias may still remain, so it’s important to continually test for and mitigate biases.
