lgb.drop_serialized

If a LightGBM model object was produced with argument `serializable=TRUE`, the R object will keep
a copy of the underlying C++ object as raw bytes, which can be used to reconstruct such object after getting
serialized and de-serialized, but at the cost of extra memory usage. If these raw bytes are not needed anymore,
they can be dropped through this function in order to save memory. Note that the object will be modified in-place.
New in version 4.0.0

Tree based algorithms can be improved by introducing boosting frameworks.
'LightGBM' is one such framework, based on Ke, Guolin et al. (2017) <https://papers.nips.cc/paper/6907-lightgbm-a-highly-efficient-gradient-boosting-decision>.
This package offers an R interface to work with it.
It is designed to be distributed and efficient with the following advantages:
1. Faster training speed and higher efficiency.
2. Lower memory usage.
3. Better accuracy.
4. Parallel learning supported.
5. Capable of handling large-scale data.
In recognition of these advantages, 'LightGBM' has been widely-used in many winning solutions of machine learning competitions.
Comparison experiments on public datasets suggest that 'LightGBM' can outperform existing boosting frameworks on both efficiency and accuracy, with significantly lower memory consumption. In addition, parallel experiments suggest that in certain circumstances, 'LightGBM' can achieve a linear speed-up in training time by using multiple machines.
