Private Weighted Random Walk Stochastic Gradient Descent

no code implementations3 Sep 2020 Ghadir Ayache, Salim El Rouayheb

To speed up the convergence, we propose instead to study random walk based SGD in which a global model is updated based on a random walk on the graph.

Mechanisms for Hiding Sensitive Genotypes with Information-Theoretic Privacy

no code implementations10 Jul 2020 Fangwei Ye, Hyunghoon Cho, Salim El Rouayheb

Motivated by the growing availability of personal genomics services, we study an information-theoretic privacy problem that arises when sharing genomic data: a user wants to share his or her genome sequence while keeping the genotypes at certain positions hidden, which could otherwise reveal critical health-related information.

Adaptive Distributed Stochastic Gradient Descent for Minimizing Delay in the Presence of Stragglers

no code implementations25 Feb 2020 Serge Kas Hanna, Rawad Bitar, Parimal Parag, Venkat Dasari, Salim El Rouayheb

One solution studied in the literature is to wait at each iteration for the responses of the fastest $k<n$ workers before updating the model, where $k$ is a fixed parameter.

Guess & Check Codes for Deletions, Insertions, and Synchronization

1 code implementation24 May 2017 Serge Kas Hanna, Salim El Rouayheb

We consider the problem of constructing codes that can correct $\delta$ deletions occurring in an arbitrary binary string of length $n$ bits.
