ada: An R Package for Stochastic Boosting
Boosting is an iterative algorithm that combines simple classification rules with ‘mediocre’ performance in terms of misclassification error rate to produce a highly accurate classification rule. Stochastic gradient boosting provides an enhancement which incorporates a random mechanism at each boosting step showing an improvement in performance and speed in generating the ensemble. ada is an R ...
متن کاملStochastic Epidemic Models
The present work concerns models of epidemic which are described by differential and stochastic differential equations. The theorems on the existence, uniqueness and properties of their solutions are stated. Introduction In nature, there are many diseases which can cause epidemics. Therefore it is useful to model the behavior of these diseases in order to control their progression. In this pape...
متن کاملstm: R Package for Structural Topic Models
This vignette demonstrates how to use the Structural Topic Model, stm, R package. The Structural Topic Model (STM) allows researchers to estimate a topic model which includes document-level meta-data. The stm package provides a range of features from model selection to extensive plotting and visualization options.
متن کاملStochastic Newton Sampler: The R Package sns
The R package sns implements Stochastic Newton Sampler (SNS), a Metropolis-Hastings Monte Carlo Markov Chain algorithm where the proposal density function is a multivariate Gaussian based on a local, second-order Taylor-series expansion of log-density. The mean of the proposal function is the full Newton step in Newton-Raphson optimization algorithm. Taking advantage of the local, multivariate ...
متن کاملEvidence synthesis for stochastic epidemic models
In recent years the role of epidemic models in informing public health policies has progressively grown. Models have become increasingly realistic and more complex, requiring the use of multiple data sources to estimate all quantities of interest. This review summarises the different types of stochastic epidemic models that use evidence synthesis and highlights current challenges.
