## Latest Updates
2020-12-21: A new
[vectorized version of the TF 2 optimizer](https://github.com/tensorflow/privacy/blob/master/tensorflow_privacy/privacy/optimizers/dp_optimizer_keras_vectorized.py)
is available, which can deliver much faster performance. We recommend trying it
first, and to fall back to using the original non-vectorized version only if
this fails. We are thankful to the
[authors of this paper](https://arxiv.org/abs/2010.09063) for spurring this
change.
