Machine learning techniques based on neural networks are achieving remarkable results in a wide variety of domains. Often, the training of models requires large, representative datasets, which may be crowd-sourced and contain sensitive information. The models should not expose private information in these datasets. Differential Privacy is a standard privacy definition that implies a strong and concrete guarantee on protecting such information.

In this talk, I'll then outline two recent approaches to training deep neural networks while providing a differential privacy guarantee, and some new analysis tools we developed in the process. Our implementation and experiments demonstrate that we can train deep neural networks with non-convex objectives, under a modest privacy budget, and at a manageable cost in software complexity, training efficiency, and model quality.
