EDDI: Efficient Dynamic Discovery of High-Value Information with Partial VAE

1 code implementation ICLR 2019 Chao Ma, Sebastian Tschiatschek, Konstantina Palla, José Miguel Hernández-Lobato, Sebastian Nowozin, Cheng Zhang

Many real-life decision-making situations allow further relevant information to be acquired at a specific cost, for example, in assessing the health status of a patient we may decide to take additional measurements such as diagnostic tests or imaging scans before making a final assessment.

A Birth-Death Process for Feature Allocation

no code implementations ICML 2017 Konstantina Palla, David Knowles, Zoubin Ghahramani

We propose a Bayesian nonparametric prior over feature allocations for sequential data, the birth-death feature allocation process (BDFP).

Bayesian Nonparametrics for Sparse Dynamic Networks

no code implementations6 Jul 2016 Cian Naik, Francois Caron, Judith Rousseau, Yee Whye Teh, Konstantina Palla

In this paper we propose a Bayesian nonparametric approach to modelling sparse time-varying networks.

A nonparametric variable clustering model

no code implementations NeurIPS 2012 Konstantina Palla, Zoubin Ghahramani, David A. Knowles

Factor analysis models effectively summarise the covariance structure of high dimensional data, but the solutions are typically hard to interpret.


SiGMa: Simple Greedy Matching for Aligning Large Knowledge Bases

1 code implementation19 Jul 2012 Simon Lacoste-Julien, Konstantina Palla, Alex Davies, Gjergji Kasneci, Thore Graepel, Zoubin Ghahramani

The Internet has enabled the creation of a growing number of large-scale knowledge bases in a variety of domains containing complementary information.
