Abstract
Being among the most popular and efficient classification and regression methods currently available, implementations of support vector machines exist in almost every popular programming language. Currently four R packages contain SVM related software. The purpose of this paper is to present and compare these implementations. (authors' abstract)

Comorbidity: a network perspective.

TL;DR: A method to visualize comorbidity networks is proposed and it is argued that this approach generates realistic hypotheses about pathways to comor bidity, overlapping symptoms, and diagnostic boundaries, that are not naturally accommodated by latent variable models.

Where is positional uncertainty a problem for species distribution modelling

TL;DR: It is proposed that local spatial association is a way to identify the species occurrence records that require treatment for positional uncertainty and developed and presented a tool in the R environment to target observations that are likely to create error in the output from SDMs as a result of positional uncertainty.

Geological mapping using remote sensing data: A comparison of five machine learning algorithms, their response to variations in the spatial distribution of training data and the use of explicit spatial information

TL;DR: This work identifies Random Forests as a good first choice algorithm for the supervised classification of lithology using remotely sensed geophysical data and indicates that as training data becomes increasingly dispersed across the region under investigation, MLA predictive accuracy improves dramatically.

Predictive models for forecasting hourly urban water demand

TL;DR: This paper describes and compares a series of predictive models for forecasting water demand obtained using time series data from water consumption in an urban area of a city in south-eastern Spain, and proposes a simple model based on the weighted demand profile resulting from the exploratory analysis of the data.

A bitter cup: climate change profile of global production of Arabica and Robusta coffee

TL;DR: In this paper, the authors used machine learning algorithms to derive functions of climatic suitability from a database of geo-referenced production locations, and the resulting multi-model ensemble suggests that higher temperatures may reduce yields of C. arabica, while C. canephora could suffer from increasing variability of intra-seasonal temperatures.

Fast training of support vector machines using sequential minimal optimization, advances in kernel methods

J. C. Platt
TL;DR: SMO breaks this large quadratic programming problem into a series of smallest possible QP problems, which avoids using a time-consuming numerical QP optimization as an inner loop and hence SMO is fastest for linear SVMs and sparse data sets.
