Boosting as a Product of Experts
Narayanan U. Edakunni,Gary Brown,Tim Kovacs
Computer Science , 2012,
Abstract: In this paper, we derive a novel probabilistic model of boosting as a Product of Experts. We re-derive the boosting algorithm as a greedy incremental model selection procedure which ensures that addition of new experts to the ensemble does not decrease the likelihood of the data. These learning rules lead to a generic boosting algorithm - POE- Boost which turns out to be similar to the AdaBoost algorithm under certain assumptions on the expert probabilities. The paper then extends the POEBoost algorithm to POEBoost.CS which handles hypothesis that produce probabilistic predictions. This new algorithm is shown to have better generalization performance compared to other state of the art algorithms.
TreeVector: Scalable, Interactive, Phylogenetic Trees for the Web
Ralph Pethica,Gary Barker,Tim Kovacs,Julian Gough
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0008934
Abstract: Phylogenetic trees are complex data forms that need to be graphically displayed to be human-readable. Traditional techniques of plotting phylogenetic trees focus on rendering a single static image, but increases in the production of biological data and large-scale analyses demand scalable, browsable, and interactive trees.
Invertibility-preserving maps of -algebras with real rank zero
Istvan Kovacs
Abstract and Applied Analysis , 2005, DOI: 10.1155/aaa.2005.685
Abstract: In 1996, Harris and Kadison posed the following problem: show that a linear bijection between C∗-algebras that preserves the identity and the set of invertible elements is a Jordan isomorphism. In this paper, we show that if A and B are semisimple Banach algebras and Φ:A→B is a linear map onto B that preserves the spectrum of elements, then Φ is a Jordan isomorphism if either A or B is a C∗-algebra of real rank zero. We also generalize a theorem of Russo.
