Time-Varying Interaction Estimation Using Ensemble Methods

no code implementations25 Jun 2019 Brandon Oselio, Amir Sadeghian, Silvio Savarese, Alfred Hero

Directed information (DI) is a useful tool to explore time-directed interactions in multivariate data.

Learning to Bound the Multi-class Bayes Error

no code implementations15 Nov 2018 Salimeh Yasaei Sekeh, Brandon Oselio, Alfred O. Hero

Providing a tight bound on the BER that is also feasible to estimate has been a challenge.

Consistent Alignment of Word Embedding Models

no code implementations24 Feb 2017 Cem Safak Sahin, Rajmonda S. Caceres, Brandon Oselio, William M. Campbell

Word embedding models offer continuous vector representations that can capture rich contextual semantics based on their word co-occurrence patterns.

Clustering

Similarity Function Tracking using Pairwise Comparisons

no code implementations7 Jan 2017 Kristjan Greenewald, Stephen Kelley, Brandon Oselio, Alfred O. Hero III

We propose Online Convex Ensemble StrongLy Adaptive Dynamic Learning (OCELAD), a general adaptive, online approach for learning and tracking optimal metrics as they change over time that is highly robust to a variety of nonstationary behaviors in the changing metric.
