Anand D. Sarwate

I am an Associate Professor in the Department of Electrical and Computer Engineering at Rutgers, The State University of New Jersey. I also am a member of the graduate faculty in the Department of Computer Science and the Department of Statistics. I like to work on problems that involve probability, mathematical statistics,
and optimization, with applications in information theory, communication, signal processing, and machine learning. I’m particularly interested in how these things intersect in the context of distributed/decentralized systems with constraints like privacy, bandwidth, latency, power, and so on.

This page is still somewhat under construction. I anticipate that will be the state for quite a while.

May 23, 2025	A bunch of updates after not so many updates: The site has been updated with more content, including slides from some recent talks. I was awarded the Presidential Outstanding Faculty Scholar Award by Rutgers. This is given to faculty getting promoted to Professor (from Associate). However, I have not received official notification for the promotion so I’ll just assume the award is a good sign (?) Our monograph is finally done! Dey et al, Codes for Adversaries: Between Worst-Case and Average-Case Jamming, Foundations and Trends in Communications and Information Theory, 2024. This is is the culmination of 15+ years of research we’ve been doing on adversarial channel models! Preprints! Vargas et al., Understanding Generative AI Content with Embedding Models, under review. Tao et al., Privacy-Preserving Visualization of Brain Functional Connectivity, about to be submitted. Banerjee et al., Measuring model variability using robust non-parametric testing, revision under review. Journal and conference papers! Tao and Sarwate, Differentially Private Distribution Estimation Using Functional Approximation, ICASSP 2025. We look at CDF approximation using functional approximation. A journal version is in the works. Wu et al., Learning to Help in Multi-Class Settings, ICLR 2025. We study a variation on learning with abstention to design effective “helpers” for resource-constrained devices needing to do ML/AI stuff. Tao et al., Federated Privacy-Preserving Visualization: A Vision Paper, IEEE BigData 2024. We’re looking at where and when private visualization might be useful. Sathyavageeswaran et al., Timely Offloading in Mobile Edge Cloud Systems, ITW 2024. We use an MDP framework to analyze computational offloading policies. Dey, et al., Computationally Efficient Codes for Strongly Dobrushin-Stambler Nonsymmetrizable Oblivious AVCs, ISIT 2024. We develop polynomial time codes for classes of adversarial channels! A. D. Sarwate, Machine learning with differential privacy, a chapter in the Handbook of Sharing Confidential Data Differential Privacy, Secure Multiparty Computation, and Synthetic Data from CRC. A limited survey of “classical” ML under differential privacy, more aimed at potential practitioners. Rootes-Murdy et al., Cortical similarities in psychiatric and mood disorders identified in federated VBM analysis via COINSTAC, Patterns, 2024. A use-case for COINSTAC, the federated learning platform for neuroimaging analysis on which I have been collaborating for the last 10 years.

Privacy protection is important in visualization due to the risk of leaking personal sensitive information. In this paper, we study the problem of privacy-preserving visualizations using differential privacy, employing biomedical data from neuroimaging as a use case. We investigate several approaches based on perturbing correlation values and characterize their privacy cost and the impact of pre- and post-processing. To obtain a better privacy/visual utility tradeoff, we propose workflows for connectogram and seed-based connectivity visualizations, respectively. These workflows successfully generate visualizations similar to their non-private counterparts. Experiments show that qualitative assessments can be preserved while guaranteeing privacy. These results show that differential privacy is a promising method for protecting sensitive information in data visualization.Competing Interest StatementThe authors have declared no competing interest.

Summary Structural neuroimaging studies have identified a combination of shared and disorder-specific patterns of gray matter (GM) deficits across psychiatric disorders. Pooling large data allows for examination of a possible common neuroanatomical basis that may identify a certain vulnerability for mental illness. Large-scale collaborative research is already facilitated by data repositories, institutionally supported databases, and data archives. However, these data-sharing methodologies can suffer from significant barriers. Federated approaches augment these approaches by enabling access or more sophisticated, shareable and scaled-up analyses of large-scale data. We examined GM alterations using Collaborative Informatics and Neuroimaging Suite Toolkit for Anonymous Computation, an open-source, decentralized analysis application. Through federated analysis of eight sites, we identified significant overlap in the GM patterns (n = 4,102) of individuals with schizophrenia, major depressive disorder, and autism spectrum disorder. These results show cortical and subcortical regions that may indicate a shared vulnerability to psychiatric disorders.

Enhancing collaborative neuroimaging research: introducing COINSTAC Vaults for federated analysis and reproducibility,

Frontiers in Neuroinformatics, Jun 2023.

Abs DOI URL Bib

Collaborative neuroimaging research is often hindered by technological, policy, administrative, and methodological barriers, despite the abundance of available data. COINSTAC (The Collaborative Informatics and Neuroimaging Suite Toolkit for Anonymous Computation) is a platform that successfully tackles these challenges through federated analysis, allowing researchers to analyze datasets without publicly sharing their data. This paper presents a significant enhancement to the COINSTAC platform: COINSTAC Vaults (CVs). CVs are designed to further reduce barriers by hosting standardized, persistent, and highly-available datasets, while seamlessly integrating with COINSTAC’s federated analysis capabilities. CVs offer a user-friendly interface for self-service analysis, streamlining collaboration, and eliminating the need for manual coordination with data owners. Importantly, CVs can also be used in conjunction with open data as well, by simply creating a CV hosting the open data one would like to include in the analysis, thus filling an important gap in the data sharing ecosystem. We demonstrate the impact of CVs through several functional and structural neuroimaging studies utilizing federated analysis showcasing their potential to improve the reproducibility of research and increase sample sizes in neuroimaging studies.

Federated Analysis in COINSTAC Reveals Functional Network Connectivity and Spectral Links to Smoking and Alcohol Consumption in Nearly 2,000 Adolescent Brains,

Neuroinformatics, Nov 2022.

Abs DOI URL Bib

With the growth of decentralized/federated analysis approaches in neuroimaging, the opportunities to study brain disorders using data from multiple sites has grown multi-fold. One such initiative is the Neuromark, a fully automated spatially constrained independent component analysis (ICA) that is used to link brain network abnormalities among different datasets, studies, and disorders while leveraging subject-specific networks. In this study, we implement the neuromark pipeline in COINSTAC, an open-source neuroimaging framework for collaborative/decentralized analysis. Decentralized exploratory analysis of nearly 2000 resting-state functional magnetic resonance imaging datasets collected at different sites across two cohorts and co-located in different countries was performed to study the resting brain functional network connectivity changes in adolescents who smoke and consume alcohol. Results showed hypoconnectivity across the majority of networks including sensory, default mode, and subcortical domains, more for alcohol than smoking, and decreased low frequency power. These findings suggest that global reduced synchronization is associated with both tobacco and alcohol use. This proof-of-concept work demonstrates the utility and incentives associated with large-scale decentralized collaborations spanning multiple sites.
