Open-Source Software for Online Machine Learning

In contrast to Batch Machine Learning (BML), there are only a few open-source software packages for Online Machine Learning (OML). This chapter describes the availability of open-source software packages (especially in R/Python) that provide OML methods and algorithms to solve tasks such as regression, classification, clustering, or outlier detection. Section 8.1 gives an overview of the software, followed by a description of the corresponding packages. Then, Sect. 8.2 provides a comparative overview of the scope of the individual software packages. The chapter concludes with a comparison of the most important programming languages in the field of Machine Learning (ML) (Sect. 8.3).
