Parameter docs for fields used in lgb.Dataset construction

Arguments

• label: vector of labels to use as the target variable
• weight: numeric vector of sample weights
• init_score: initial score is the base prediction lightgbm will boost from
• group: used for learning-to-rank tasks. An integer vector describing how to group rows together as ordered results from the same set of candidate results to be ranked. For example, if you have a 100-document dataset with group = c(10, 20, 40, 10, 10, 10), that means that you have 6 groups, where the first 10 records are in the first group, records 11-30 are in the second group, etc.
