Preference Completion from Partial Rankings
Suriya Gunasekar, Oluwasanmi Koyejo, Joydeep Ghosh
We propose a novel and efficient algorithm for the collaborative preference completion problem, which involves jointly estimating individualized rankings for a set of entities over…
Online Classification with Complex Metrics
Bowei Yan, Oluwasanmi Koyejo, Kai Zhong +1
We present a framework and analysis of consistent binary classification for complex and non-decomposable performance metrics such as the F-measure and the Jaccard measure. The prop…
Information Projection and Approximate Inference for Structured Sparse Variables
Rajiv Khanna, Joydeep Ghosh, Russell Poldrack +1
Approximate inference via information projection has been recently introduced as a general-purpose approach for efficient probabilistic inference given sparse variables. This manus…
A simple and provable algorithm for sparse diagonal CCA
Megasthenis Asteris, Anastasios Kyrillidis, Oluwasanmi Koyejo +1
Given two sets of variables, derived from a common set of samples, sparse Canonical Correlation Analysis (CCA) seeks linear combinations of a small number of variables in each set,…
Generalized Linear Models for Aggregated Data
Avradeep Bhowmik, Joydeep Ghosh, Oluwasanmi Koyejo
Databases in domains such as healthcare are routinely released to the public in aggregated form. Unfortunately, naive modeling with aggregated data may significantly diminish the a…
What's in a pattern? Examining the Type of Signal Multivariate Analysis Uncovers At the Group Level
Roee Gilron, Jonathan Rosenblatt, Oluwasanmi Koyejo +2
Multivoxel pattern analysis (MVPA) has gained enormous popularity in the neuroimaging community over the past few years. At the group level, most MVPA studies adopt an "information…
Temporal meta-states are associated with differential patterns of dynamic connectivity, network topology and attention
James M. Shine, Oluwasanmi Koyejo, Russell A. Poldrack
Little is currently known about the coordination of neural activity over longitudinal time-scales and how these changes relate to behavior. To investigate this issue, we used resti…
