Questions tagged [machine-learning]

Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.

In order to achieve differentially private machine learning can one simply apply the Laplace mechanism after an SGD scheme? If so does it work well?

Consider a standard supervised machine learning problem on private data. Instead of using DPSGD, suppose that one uses a non-private SGD scheme to produce optimal model parameters $\theta$ (done in ...

Key management problem in federated learning based on homomorphic encryption

In federated learning using homomorphic encryption, all participants in most schemes share the same pair of keys, which can easily cause key leaks and lead to data privacy leaks. After research, I ...
