Strong Duality Relations in Nonconvex Risk-Constrained Learning

no code implementations2 Dec 2023 Dionysis Kalogerias, Spyridon Pougkakiotis

Our results in particular imply zero duality gaps within the class of problems under study, both extending and improving on the state of the art in (risk-neutral) constrained learning.

Federated Learning Under Restricted User Availability

no code implementations25 Sep 2023 Periklis Theodoropoulos, Konstantinos E. Nikolakakis, Dionysis Kalogerias

Federated Learning (FL) is a decentralized machine learning framework that enables collaborative model training while respecting data privacy.

Repeated Random Sampling for Minimizing the Time-to-Accuracy of Learning

no code implementations28 May 2023 Patrik Okanovic, Roger Waleffe, Vasilis Mageirakos, Konstantinos E. Nikolakakis, Amin Karbasi, Dionysis Kalogerias, Nezihe Merve Gürel, Theodoros Rekatsinas

Methods for carefully selecting or generating a small set of training data to learn from, i. e., data pruning, coreset selection, and data distillation, have been shown to be effective in reducing the ever-increasing cost of training neural networks.

Data Compression

Select without Fear: Almost All Mini-Batch Schedules Generalize Optimally

no code implementations3 May 2023 Konstantinos E. Nikolakakis, Amin Karbasi, Dionysis Kalogerias

We establish matching upper and lower generalization error bounds for mini-batch Gradient Descent (GD) training with either deterministic or stochastic, data-independent, but otherwise arbitrary batch selection rules.
