Differential Privacy (DP) for text has recently taken the form of text paraphrasing using language models and temperature sampling to better balance privacy and utility. However, t…
Characterizing Stereotypical Bias from Privacy-preserving Pre-Training
Stefan Arnold, Rene Gröbner, Annika Schreiner
Differential Privacy (DP) can be applied to raw text by exploiting the spatial arrangement of words in an embedding space. We investigate the implications of such text privatizatio…
