Format

  • The first row describes the data provided in the file.

    Format:

    iter<\t><loss 1><loss 2><\t>...<\t><loss N>
  • The metric names are expanded by colon-separated numbers if several validation datasets are input. The numbers correspond to the serial number of the input dataset.

  • All the rows except the first contain information for the specific iteration of building the tree.

    Format:

    <tree index><\t><loss 1><loss 2><\t>...<\t><loss N>
