Function-Correcting Codes With Data Protection
Charul Rajput, B. Sundar Rajan, Ragnar Freij-Hollanti +1
Function-correcting codes (FCCs) are designed to provide error protection for the value of a function computed on the data. Existing work typically focuses solely on protecting the…
Perfectly-Private Analog Secure Aggregation in Federated Learning
Delio Jaramillo-Velez, Charul Rajput, Ragnar Freij-Hollanti +2
In federated learning, multiple parties train models locally and share their parameters with a central server, which aggregates them to update a global model. To address the risk o…
Secretive Hotplug Coded Caching
Mallikharjuna Chinnapadamala, Charul Rajput, B. Sundar Rajan
In this work, we consider a coded caching model called \textit{hotplug coded caching}, in which some users are offline during the delivery phase. The concept of Hotplug Placement D…
On Hierarchical Coded Caching with Offline Users
Rashid Ummer N. T., B. Sundar Rajan
This paper studies a two-layer hierarchical network in which some users are offline during the content delivery phase. A two-layer hierarchical network consists of a single server…
Function-Correcting Codes for Locally Bounded Functions
Charul Rajput, B. Sundar Rajan, Ragnar Freij-Hollanti +1
In this paper, we introduce a class of functions that assume only a limited number of values within a given Hamming -ball and call them locally -bounded functions. W…
Hierarchical Coded Caching in High Memory Regime with Coded Placement
Rajlaxmi Pandey, Charul Rajput, B. Sundar Rajan
We consider a two-layer hierarchical coded caching network where a server with a library of files is connected to mirrors, each having a cache memory of size . Each…
