In this context, every silo (e. g. hospital) has data from several people (e. g. patients) and needs to protect the privacy of each person's data (e. g. health records), even if the server and/or other silos try to uncover this data.

We leverage convex and bilevel optimization techniques to develop a general gradient-based parameter learning framework for neural-symbolic (NeSy) systems.

We develop simple differentially private optimization algorithms that move along directions of (expected) descent to find an approximate second-order solution for nonconvex ERM.
