[−][src]Struct xgboost::FeatureMap
Maps a feature index to a name and type, used when dumping models as text.
See dump_model for usage.
Methods
impl FeatureMap[src]
pub fn from_file<P: AsRef<Path>>(path: P) -> Result<FeatureMap>[src]
Read a FeatureMap from a file at given path.
File should contain one feature definition per line, and be of the form:
<number>\t<name>\t<type>\n
Type should be one of:
i- binary featureq- quantitative featureint- integer features
E.g.:
0 age int
1 is-parent?=yes i
2 is-parent?=no i
3 income int
