If ```agaricus.txt.test.buffer``` exists, and automatically loads from binary buffer if possible, this can speedup training process when you do training many times. You can disable it by setting ```use_buffer=0```.
- Buffer file can also be used as standalone input, i.e if buffer file exists, but original agaricus.txt.test was removed, xgboost will still run
* Deviation from LibSVM input format: xgboost is compatible with LibSVM format, with the following minor differences:
- xgboost allows feature index starts from 0
- for binary classification, the label is 1 for positive, 0 for negative, instead of +1,-1
- the feature indices in each line *do not* need to be sorted
