%description
The natural increase in the complexity of current research experiments and
data demands better tools to enhance productivity in Data Analytics. The
package is a framework designed to address the modern challenges in data
analytics workflows. The package is inspired by Experiment Line concepts.
It aims to provide seamless support for users in developing their data
mining workflows by offering a uniform data model and method API. It
enables the integration of various data mining activities, including data
preprocessing, classification, regression, clustering, and time series
prediction. It also offers options for hyper-parameter tuning and supports
integration with existing libraries and languages. Overall, the package
provides researchers with a comprehensive set of functionalities for data
science, promoting ease of use, extensibility, and integration with
various tools and libraries. Information on Experiment Line is based on
Ogasawara et al. (2009) <doi:10.1007/978-3-642-02279-1_20>.
