Convert vector of predictions to matrix format
From line 56 at https://github.com/dmlc/xgboost/blob/ef4dcce7372dbc03b5066a614727f2a6dfcbd3bc/src/objective/multiclass_obj.cc,
it appears that preds is stored in column-major order with
observations in columns and classes/models in rows
i.e., preds[k * nclass + i] is prediction for model i at index k
Usage
1
preds_to_matrix(preds, num_models)
Arguments
preds
vector of predictions as obtained from xgb.train
number
of models
Value
preds in matrix form, with num_models columns and num_obs rows
