GPU-Accelerated Primal Learning for Extremely Fast Large-Scale Classification

no code implementations NeurIPS 2020 John T. Halloran, David M. Rocke

One of the most efficient methods to solve L2-regularized primal problems, such as logistic regression and linear support vector machine (SVM) classification, is the widely used trust region Newton algorithm, TRON.

Learning Concave Conditional Likelihood Models for Improved Analysis of Tandem Mass Spectra

no code implementations NeurIPS 2018 John T. Halloran, David M. Rocke

The most widely used technology to identify the proteins present in a complex biological sample is tandem mass spectrometry, which quickly produces a large collection of spectra representative of the peptides (i. e., protein subsequences) present in the original sample.

Gradients of Generative Models for Improved Discriminative Analysis of Tandem Mass Spectra

no code implementations NeurIPS 2017 John T. Halloran, David M. Rocke

Tandem mass spectrometry (MS/MS) is a high-throughput technology used toidentify the proteins in a complex biological sample, such as a drop of blood.
