Information Leakage from Data Updates in Machine Learning Models
Tian Hui, Farhad Farokhi, Olga Ohrimenko
In this paper we consider the setting where machine learning models are retrained on updated datasets in order to incorporate the most up-to-date information or reflect distributio…
Distributionally Time-Varying Online Stochastic Optimization under Polyak-Łojasiewicz Condition with Application in Conditional Value-at-Risk Statistical Learning
Yuen-Man Pun, Farhad Farokhi, Iman Shames
In this work, we consider a sequence of stochastic optimization problems following a time-varying distribution via the lens of online optimization. Assuming that the loss function…
Learning Safety Filters for Unknown Discrete-Time Linear Systems
Farhad Farokhi, Alex S. Leong, Mohammad Zamani +1
A learning-based safety filter is developed for discrete-time linear time-invariant systems with unknown models subject to Gaussian noises with unknown covariance. Safety is charac…
Toward nonlinear dynamic control over encrypted data for infinite time horizon
Junsoo Kim, Farhad Farokhi, Iman Shames +1
Recent studies on encrypted control using homomorphic encryption allow secure operation by directly performing computations on encrypted data without decryption. Implementing dynam…
Optimal Stochastic Evasive Maneuvers Using the Schrodinger's Equation
Farhad Farokhi, Magnus Egerstedt
In this paper, preys with stochastic evasion policies are considered. The stochasticity adds unpredictable changes to the prey's path for avoiding predator's attacks. The prey's co…
Security Versus Privacy
Farhad Farokhi, Peyman Mohajerin Esfahani
Linear queries can be submitted to a server containing private data. The server provides a response to the queries systematically corrupted using an additive noise to preserve the…
