RAN-Debias: Repulsion-Attraction-Neutralization Debias



RAN-Debias: Repulsion-Attraction-Neutralization Debias

This paper presents RAN-Debias, a gender de-biasing methodology which eliminates the bias present in a word vector and alters the spatial distribution of its neighboring vectors, achieving a bias-free setting while maintaining minimal semantic offset.

This paper also proposes a new bias evaluation metric – Gender-based Illicit Proximity Estimate (GIPE), which measures the extent of undue proximity in word vectors resulting from the presence of gender-based predilections. Experiments based on a suite of evaluation metrics show that RAN-Debias significantly outperforms the state-of-the-art in reducing proximity bias (GIPE) by at least 42.02%. It also reduces direct bias, adding minimal semantic disturbance, and achieves the best performance in a downstream application task (coreference resolution).

This method not only mitigates direct bias of a word, but also reduces its associations with other words that arise from gender-based predilections.
