Scalable Bayesian Transformed Gaussian Processes

no code implementations20 Oct 2022 Xinran Zhu, Leo Huang, Cameron Ibrahim, Eric Hans Lee, David Bindel

The Bayesian transformed Gaussian process (BTG) model, proposed by Kedem and Oliviera, is a fully Bayesian counterpart to the warped Gaussian process (WGP) and marginalizes out a joint prior over input warping and kernel hyperparameters.

A fundamental problem on graph-structured data is that of quantifying similarity between graphs.

On the Distribution of Minima in Intrinsic-Metric Rotation Averaging

no code implementations CVPR 2020 Kyle Wilson, David Bindel

This is an extension of the results of [24], which used local convexity as a proxy to study the difficulty of problem.

Efficient Rollout Strategies for Bayesian Optimization

1 code implementation24 Feb 2020 Eric Hans Lee, David Eriksson, Bolong Cheng, Michael McCourt, David Bindel

Non-myopic acquisition functions consider the impact of the next $h$ function evaluations and are typically computed through rollout, in which $h$ steps of BO are simulated.

Practical Correlated Topic Modeling and Analysis via the Rectified Anchor Word Algorithm

no code implementations IJCNLP 2019 Moontae Lee, Sungjun Cho, David Bindel, David Mimno

Despite great scalability on large data and their ability to understand correlations between topics, spectral topic models have not been widely used due to the absence of reliability in real data and lack of practical implementations.

Scalable Log Determinants for Gaussian Process Kernel Learning

3 code implementations NeurIPS 2017 Kun Dong, David Eriksson, Hannes Nickisch, David Bindel, Andrew Gordon Wilson

For applications as varied as Bayesian neural networks, determinantal point processes, elliptical graphical models, and kernel learning for Gaussian processes (GPs), one must compute a log determinant of an $n \times n$ positive definite matrix, and its derivatives - leading to prohibitive $\mathcal{O}(n^3)$ computations.

Spectral inference provides fast algorithms and provable optimality for latent topic analysis.

Uncovering the Small Community Structure in Large Networks: A Local Spectral Approach

1 code implementation25 Sep 2015 Yixuan Li, Kun He, David Bindel, John Hopcroft

Nowadays, as we often explore networks with billions of vertices and find communities of size hundreds, it is crucial to shift our attention from macroscopic structure to microscopic structure when dealing with large networks.
