Abstract
LIBSVM is a library for Support Vector Machines (SVMs). We have been actively developing this package since the year 2000. The goal is to help users to easily apply SVM to their applications. LIBSVM has gained wide popularity in machine learning and many other areas. In this article, we present all implementation details of LIBSVM. Issues such as solving SVM optimization problems theoretical convergence multiclass classification probability estimates and parameter selection are discussed in detail.

Signal quality indices and data fusion for determining clinical acceptability of electrocardiograms

TL;DR: A completely automated algorithm to detect poor-quality electrocardiograms (ECGs) is described, based on both novel and previously published signal quality metrics, originally designed for intensive care monitoring and expected to achieve an accuracy closer to 100%.

Loda: Lightweight on-line detector of anomalies

TL;DR: This work shows that an ensemble of very weak detectors can lead to a strong anomaly detector with a performance equal to or better than state of the art methods, and compares Loda to several state ofThe art anomaly detectors in two settings: batch training and on-line training on data streams.

Head Pose Estimation for Driver Assistance Systems: A Robust Algorithm and Experimental Evaluation

TL;DR: This work presents an identity-and lighting-invariant system to estimate a driver's head pose, which is fully autonomous and operates online in daytime and nighttime driving conditions, using a monocular video camera sensitive to visible and near-infrared light.

A comparison of methods for multiclass support vector machines

TL;DR: Decomposition implementations for two "all-together" multiclass SVM methods are given and it is shown that for large problems methods by considering all data at once in general need fewer support vectors.
