Lightgbm free_raw_data false

WebLightGBM constructs its data format, called a "Dataset", from tabular data. By default, that Dataset object on the R side does not keep a copy of the raw data. This reduces LightGBM's memory consumption, but it means that the Dataset object cannot be changed after it has been constructed. WebLightGBM Python package is a gradient boosting framework that uses a tree-based learning algorithm. LightGBM grows trees vertically, whereas other boosting algorithms grow trees horizontally; this means that LightGBM grows tree leafwise, and other algorithms grow trees levelwise. It chooses the leaf with maximum delta loss to grow.
