Collaborative and Distributed Bayesian Optimization via Consensus: Showcasing the Power of Collaboration for Optimal Design

1 code implementation25 Jun 2023 Xubo Yue, Raed Al Kontar, Albert S. Berahas, Yang Liu, Blake N. Johnson

Empirically, through simulated datasets and a real-world collaborative sensor design experiment, we show that our framework can effectively accelerate and improve the optimal design process and benefit all participants.

Federated Data Analytics: A Study on Linear Models

no code implementations15 Jun 2022 Xubo Yue, Raed Al Kontar, Ana María Estrada Gómez

In this work, we take a step back to develop an FDA treatment for one of the most fundamental statistical models: linear regression.

Federated Gaussian Process: Convergence, Automatic Personalization and Multi-fidelity Modeling

1 code implementation28 Nov 2021 Xubo Yue, Raed Al Kontar

In this paper, we propose \texttt{FGPR}: a Federated Gaussian process ($\mathcal{GP}$) regression framework that uses an averaging strategy for model aggregation and stochastic gradient descent for local client computations.

GIFAIR-FL: A Framework for Group and Individual Fairness in Federated Learning

no code implementations5 Aug 2021 Xubo Yue, Maher Nouiehed, Raed Al Kontar

In this paper we propose \texttt{GIFAIR-FL}: a framework that imposes \textbf{G}roup and \textbf{I}ndividual \textbf{FAIR}ness to \textbf{F}ederated \textbf{L}earning settings.

SALR: Sharpness-aware Learning Rate Scheduler for Improved Generalization

no code implementations10 Nov 2020 Xubo Yue, Maher Nouiehed, Raed Al Kontar

In an effort to improve generalization in deep learning and automate the process of learning rate scheduling, we propose SALR: a sharpness-aware learning rate update technique designed to recover flat minimizers.

In an effort to improve generalization in deep learning, we propose SALR: a sharpness-aware learning rate update technique designed to recover flat minimizers.

Why Non-myopic Bayesian Optimization is Promising and How Far Should We Look-ahead? A Study via Rollout

no code implementations4 Nov 2019 Xubo Yue, Raed Al Kontar

We then provide both a theoretical and practical guideline to decide on the rolling horizon stagewise.

The Renyi Gaussian Process: Towards Improved Generalization

no code implementations15 Oct 2019 Xubo Yue, Raed Kontar

We introduce an alternative closed form lower bound on the Gaussian process ($\mathcal{GP}$) likelihood based on the R\'enyi $\alpha$-divergence.

Variational Inference of Joint Models using Multivariate Gaussian Convolution Processes

no code implementations9 Mar 2019 Xubo Yue, Raed Kontar

We present a non-parametric prognostic framework for individualized event prediction based on joint modeling of both longitudinal and time-to-event data.
