Debiasing Sentence Embedders through Contrastive Word Pairs

1 code implementation27 Mar 2024 Philip Kenneweg, Sarah Schröder, Alexander Schulz, Barbara Hammer

It is problematic that most debiasing approaches are directly transferred from word embeddings, therefore these approaches fail to take into account the nonlinear nature of sentence embedders and the embeddings they produce.

Intelligent Learning Rate Distribution to reduce Catastrophic Forgetting in Transformers

1 code implementation27 Mar 2024 Philip Kenneweg, Alexander Schulz, Sarah Schröder, Barbara Hammer

We combine the learning rate distributions thus found and show that they generalize to better performance with respect to the problem of catastrophic forgetting.

Semantic Properties of cosine based bias scores for word embeddings

no code implementations27 Jan 2024 Sarah Schröder, Alexander Schulz, Fabian Hinder, Barbara Hammer

Furthermore, we formally analyze cosine based scores from the literature with regard to these requirements.

The SAME score: Improved cosine based bias score for word embeddings

no code implementations28 Mar 2022 Sarah Schröder, Alexander Schulz, Philip Kenneweg, Robert Feldhans, Fabian Hinder, Barbara Hammer

Furthermore, we thoroughly investigate the existing cosine-based scores and their limitations in order to show why these scores fail to report biases in some situations.

Evaluating Metrics for Bias in Word Embeddings

no code implementations15 Nov 2021 Sarah Schröder, Alexander Schulz, Philip Kenneweg, Robert Feldhans, Fabian Hinder, Barbara Hammer

However, lately some works have raised doubts about these metrics showing that even though such metrics report low biases, other tests still show biases.
