Reconstructing Training Data from Multiclass Neural Networks. (arXiv:2305.03350v1 [cs.LG])
cs.CV updates on arXiv.org arxiv.org
Reconstructing samples from the training set of trained neural networks is a
major privacy concern. Haim et al. (2022) recently showed that it is possible
to reconstruct training samples from neural network binary classifiers, based
on theoretical results about the implicit bias of gradient methods. In this
work, we present several improvements and new insights over this previous work.
As our main improvement, we show that training-data reconstruction is possible
in the multi-class setting and that the reconstruction quality is …
