(bagging). The model is fit to these smaller data sets and the predictions are aggregated. Several instances of the same data can be used repeatedly through replacement sampling, and the result is that trees that are not only trained on different sets of data, but also different features ...
Qualitative research methodsEach of the research approaches involve using one or more data collection methods.
