Building Classifiers to Predict the Start of Glucose-Lowering Pharmacotherapy Using Belgian Health Expenditure Data
Marc Claesen, Frank De Smet, Pieter Gillard +2
Early diagnosis is important for type 2 diabetes (T2D) to improve patient prognosis, prevent complications and reduce long-term treatment costs. We present a novel risk profiling a…
Assessing binary classifiers using only positive and unlabeled data
Marc Claesen, Jesse Davis, Frank De Smet +1
Assessing the performance of a learned model is a crucial part of machine learning. However, in some domains only positive and unlabeled examples are available, which prohibits the…
Hyperparameter Search in Machine Learning
Marc Claesen, Bart De Moor
We introduce the hyperparameter search problem in the field of machine learning and discuss its main challenges from an optimization perspective. Machine learning methods attempt t…
Easy Hyperparameter Search Using Optunity
Marc Claesen, Jaak Simm, Dusan Popovic +2
Optunity is a free software package dedicated to hyperparameter optimization. It contains various types of solvers, ranging from undirected methods to direct search, particle swarm…
EnsembleSVM: A Library for Ensemble Learning Using Support Vector Machines
Marc Claesen, Frank De Smet, Johan Suykens +1
EnsembleSVM is a free software package containing efficient routines to perform ensemble learning with support vector machine (SVM) base models. It currently offers ensemble method…
Fast Prediction with SVM Models Containing RBF Kernels
Marc Claesen, Frank De Smet, Johan A. K. Suykens +1
We present an approximation scheme for support vector machine models that use an RBF kernel. A second-order Maclaurin series approximation is used for exponentials of inner product…
A Robust Ensemble Approach to Learn From Positive and Unlabeled Data Using SVM Base Models
Marc Claesen, Frank De Smet, Johan A. K. Suykens +1
We present a novel approach to learn binary classifiers when only positive and unlabeled instances are available (PU learning). This problem is routinely cast as a supervised task…
