Species distribution dataset
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
This dataset represents the geographic distribution of two species in Central and
|
||
|
|
South America. The two species are:
|
||
|
|
|
||
|
|
- `"Bradypus variegatus" <http://www.iucnredlist.org/details/3038/0>`_ ,
|
||
|
|
the Brown-throated Sloth.
|
||
|
|
|
||
|
|
- `"Microryzomys minutus" <http://www.iucnredlist.org/details/13408/0>`_ ,
|
||
|
|
also known as the Forest Small Rice Rat, a rodent that lives in Peru,
|
||
|
|
Colombia, Ecuador, Peru, and Venezuela.
|
||
|
|
|
||
|
|
The dataset is not a typical dataset since a :class:`~sklearn.datasets.base.Bunch`
|
||
|
|
containing the attributes `data` and `target` is not returned. Instead, we have
|
||
|
|
information allowing to create a "density" map of the different species.
|
||
|
|
|
||
|
|
The grid for the map can be built using the attributes `x_left_lower_corner`,
|
||
|
|
`y_left_lower_corner`, `Nx`, `Ny` and `grid_size`, which respectively correspond
|
||
|
|
to the x and y coordinates of the lower left corner of the grid, the number of
|
||
|
|
points along the x- and y-axis and the size of the step on the grid.
|
||
|
|
|
||
|
|
The density at each location of the grid is contained in the `coverage` attribute.
|
||
|
|
|
||
|
|
Finally, the `train` and `test` attributes contain information regarding the location
|
||
|
|
of a species at a specific location.
|
||
|
|
|
||
|
|
The dataset is provided by Phillips et. al. (2006).
