Controlled privacy leakage propagation throughout overlapping grouped learning
Shahrzad Kiani, Franziska Boenisch, Stark C. Draper
Federated Learning (FL) is the standard protocol for collaborative learning. In FL, multiple workers jointly train a shared model. They exchange model updates calculated on their d…
Differentially Private Federated Learning With Time-Adaptive Privacy Spending
Shahrzad Kiani, Nupur Kulkarni, Adam Dziedzic +2
Federated learning (FL) with differential privacy (DP) provides a framework for collaborative machine learning, enabling clients to train a shared model while adhering to strict pr…
Hierarchical coded elastic computing
Shahrzad Kiani, Tharindu Adikari, Stark C. Draper
Elasticity is offered by cloud service providers to exploit under-utilized computing resources. The low-cost elastic nodes can leave and join any time during the computation cycle.…
Successive Approximation Coding for Distributed Matrix Multiplication
Shahrzad Kiani, Stark C. Draper
Coded distributed computing was recently introduced to mitigate the effect of stragglers on distributed computing. This paper combines ideas of approximate computing with coded com…
Hierarchical Coded Matrix Multiplication
Shahrzad Kiani, Nuwan Ferdinand, Stark C. Draper
In distributed computing systems slow working nodes, known as stragglers, can greatly extend finishing times. Coded computing is a technique that enables straggler-resistant comput…
Cuboid Partitioning for Hierarchical Coded Matrix Multiplication
Shahrzad Kiani, Nuwan Ferdinand, Stark C. Draper
Coded matrix multiplication is a technique to enable straggler-resistant multiplication of large matrices in distributed computing systems. In this paper, we first present a concep…
Hierarchical Coded Matrix Multiplication
Shahrzad Kiani, Nuwan Ferdinand, Stark C. Draper
Slow working nodes, known as stragglers, can greatly reduce the speed of distributed computation. Coded matrix multiplication is a recently introduced technique that enables stragg…
Exploitation of Stragglers in Coded Computation
Shahrzad Kiani, Nuwan Ferdinand, Stark C. Draper
In cloud computing systems slow processing nodes, often referred to as "stragglers", can significantly extend the computation time. Recent results have shown that error correction…
Iterative method for simultaneous sparse approximation
Sahar Sadrizadeh, Shahrzad Kiani, Mahdi Boloursaz +1
This paper studies the problem of Simultaneous Sparse Approximation (SSA). This problem arises in many applications which work with multiple signals maintaining some degree of depe…
Heart Rate Tracking using Wrist-Type Photoplethysmographic (PPG) Signals during Physical Exercise with Simultaneous Accelerometry
Mahdi Boloursaz Mashhadi, Ehsan Asadi, Mohsen Eskandari +2
This paper considers the problem of casual heart rate tracking during intensive physical exercise using simultaneous 2 channel photoplethysmographic (PPG) and 3 dimensional (3D) ac…
