Building Classifiers to Predict the Start of Glucose-Lowering Pharmacotherapy Using Belgian Health Expenditure Data

no code implementations28 Apr 2015 Marc Claesen, Frank De Smet, Pieter Gillard, Chantal Mathieu, Bart De Moor

We present a novel risk profiling approach based exclusively on health expenditure data that is available to Belgian mutual health insurers.

Assessing binary classifiers using only positive and unlabeled data

2 code implementations26 Apr 2015 Marc Claesen, Jesse Davis, Frank De Smet, Bart De Moor

We provide theoretical bounds on the quality of our estimates, illustrate the importance of estimating the fraction of positives in the unlabeled set and demonstrate empirically that we are able to reliably estimate ROC and PR curves on real data.

EnsembleSVM: A Library for Ensemble Learning Using Support Vector Machines

1 code implementation4 Mar 2014 Marc Claesen, Frank De Smet, Johan Suykens, Bart De Moor

EnsembleSVM is a free software package containing efficient routines to perform ensemble learning with support vector machine (SVM) base models.

Ensemble Learning

Fast Prediction with SVM Models Containing RBF Kernels

1 code implementation4 Mar 2014 Marc Claesen, Frank De Smet, Johan A. K. Suykens, Bart De Moor

We present an approximation scheme for support vector machine models that use an RBF kernel.

A Robust Ensemble Approach to Learn From Positive and Unlabeled Data Using SVM Base Models

1 code implementation13 Feb 2014 Marc Claesen, Frank De Smet, Johan A. K. Suykens, Bart De Moor

The included benchmark comprises three settings with increasing label noise: (i) fully supervised, (ii) PU learning and (iii) PU learning with false positives.
