pyts.datasets.load_gunpoint(return_X_y=False)[source]

Load and return the GunPoint dataset.

This dataset involves one female actor and one male actor making a motion with their hand. The two classes are: Gun-Draw and Point: For Gun-Draw the actors have their hands by their sides. They draw a replicate gun from a hip-mounted holster, point it at a target for approximately one second, then return the gun to the holster, and their hands to their sides. For Point the actors have their gun by their sides. They point with their index fingers to a target for approximately one second, and then return their hands to their sides. For both classes, we tracked the centroid of the actor’s right hands in both X- and Y-axes, which appear to be highly correlated. The data in the archive is just the X-axis.

Training samples 50
Test samples 150
Timestamps 150
Classes 2
Parameters:
return_X_y : bool (default = False)

If True, return (data_train, data_test, target_train, target_test) instead of a Bunch object.

Returns:
data : Bunch

Dictionary-like object, with attributes:

data_train : array of floats

The time series in the training set.

data_test : array of floats

The time series in the test set.

target_train : array of integers

The classification labels in the training set.

target_test : array of integers

The classification labels in the test set.

DESCR : str

The full description of the dataset.

url : str

The url of the dataset.

(data_train, data_test, target_train, target_test) : tuple if return_X_y is True

Examples

>>> from pyts.datasets import load_gunpoint
>>> bunch = load_gunpoint()
>>> bunch.data_train.shape
(50, 150)
>>> X_train, X_test, y_train, y_test = load_gunpoint(return_X_y=True)
>>> X_train.shape
(50, 150)
