MetisFL: An Embarrassingly Parallelized Controller for Scalable & Efficient Federated Learning Workflows

no code implementations1 Nov 2023 Dimitris Stripelis, Chrysovalantis Anastasiou, Patrick Toral, Armaghan Asghar, Jose Luis Ambite

The controller is responsible for managing the execution of FL workflows across learners and the learners for training and evaluating federated models over their private datasets.

Federated Learning over Harmonized Data Silos

no code implementations15 May 2023 Dimitris Stripelis, Jose Luis Ambite

Federated Learning is a distributed machine learning approach that enables geographically distributed data silos to collaboratively learn a joint machine learning model without sharing data.

Secure & Private Federated Neuroimaging

no code implementations11 May 2022 Dimitris Stripelis, Umang Gupta, Hamza Saleem, Nikhil Dhinagar, Tanmay Ghai, Rafael Chrysovalantis Anastasiou, Armaghan Asghar, Greg Ver Steeg, Srivatsan Ravi, Muhammad Naveed, Paul M. Thompson, Jose Luis Ambite

Each site trains the neural network over its private data for some time, then shares the neural network parameters (i. e., weights, gradients) with a Federation Controller, which in turn aggregates the local models, sends the resulting community model back to each site, and the process repeats.

Federated Learning

Federated Progressive Sparsification (Purge, Merge, Tune)+

no code implementations26 Apr 2022 Dimitris Stripelis, Umang Gupta, Greg Ver Steeg, Jose Luis Ambite

Second, the models are incrementally constrained to a smaller set of parameters, which facilitates alignment/merging of the local models and improved learning performance at high sparsification rates.

Secure Neuroimaging Analysis using Federated Learning with Homomorphic Encryption

no code implementations7 Aug 2021 Dimitris Stripelis, Hamza Saleem, Tanmay Ghai, Nikhil Dhinagar, Umang Gupta, Chrysovalantis Anastasiou, Greg Ver Steeg, Srivatsan Ravi, Muhammad Naveed, Paul M. Thompson, Jose Luis Ambite

Federated learning (FL) enables distributed computation of machine learning models over various disparate, remote data sources, without requiring to transfer any individual data to a centralized location.

Benchmarking Federated Learning

Semi-Synchronous Federated Learning for Energy-Efficient Training and Accelerated Convergence in Cross-Silo Settings

no code implementations4 Feb 2021 Dimitris Stripelis, Jose Luis Ambite

There are situations where data relevant to machine learning problems are distributed across multiple locations that cannot share the data due to regulatory, competitiveness, or privacy reasons.

BIG-bench Machine Learning Federated Learning

Accelerating Federated Learning in Heterogeneous Data and Computational Environments

no code implementations25 Aug 2020 Dimitris Stripelis, Jose Luis Ambite

There are situations where data relevant to a machine learning problem are distributed among multiple locations that cannot share the data due to regulatory, competitiveness, or privacy reasons.

NSEEN: Neural Semantic Embedding for Entity Normalization

no code implementations19 Nov 2018 Shobeir Fakhraei, Joel Mathew, Jose Luis Ambite

An important task in this process is entity normalization, which consists of mapping noisy entity mentions in text to canonical entities in well-known reference sets.
