Update the results of fine-tuning RoBERTa-large with large batchsize and full precision.

Our code for fine-tuning BERT models with differential privacy now supports loading official RoBERTa checkpoints.

This repo provides some example code to help you get started with differentially private deep learning.

Our implementation uses Pytorch. We cover several algorithms including Differentially Private SGD [1], Gradient Embedding Perturbation [2], and Reparametrized Gradient Perturbation [3].

In the vision folder, we implement the algorithms in [1,2,3] to train deep ResNets on benchmark vision datasets.

In the language folder, we implement the algorithm in [3] to fine-tune BERT models on four tasks from the GLUE benchrmark.
