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.

Interpretable classifiers using rules and bayesian analysis: building a better stroke prediction model

TL;DR: In this paper, a generative model called Bayesian rule lists (BRL) is proposed to predict the risk of stroke in patients with atrial fibrillation, which can be used to produce highly accurate and interpretable medical scoring systems.

Detecting Hidden Messages Using Higher-Order Statistics and Support Vector Machines

TL;DR: In this article, a wavelet-like decomposition is used to build higher-order statistical models of natural images and support vector machines are then used to discriminate between untouched and adulterated images.

NRC-Canada: Building the State-of-the-Art in Sentiment Analysis of Tweets

TL;DR: This paper describes how it created two state-of-the-art SVM classifiers, one to detect the sentiment of messages such as tweets and SMS (message-level task) and one to detects the sentimentof a term within a message (term-leveltask).

Cost-Sensitive Learning of Deep Feature Representations From Imbalanced Data

TL;DR: In this article, a cost sensitive deep neural network (CoSen) is proposed to learn robust feature representations for both the majority and minority classes, which jointly optimizes the class-dependent costs and the neural network parameters.

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.
