Samples.slice(end, start=0)[source]#

Slice the Samples object.

The attribute arrays are sliced along a user-specified start and end index.

startint, default 0: The start index of the slice. Must be lower than end.

Returns:

sliceSamples: The Samples object sliced according to start and end arguments.

Examples

>>> from smash.factory import generate_samples
>>> problem = {"num_vars": 2, "names": ["cp", "llr"], "bounds": [[1, 200], [1, 500]]}

Generate samples

>>> sample = generate_samples(problem, n=5, random_state=1)
>>> sample.to_dataframe()
           cp         llr
0   83.987379   47.076959
1  144.344574   93.943845
2    1.022761  173.434803
3   61.164182  198.986970
4   30.204422  269.869550

Slice the first two sets

>>> sample_slice = sample.slice(2)
>>> sample_slice.to_dataframe()
           cp        llr
0   83.987379  47.076959
1  144.344574  93.943845

Slice between start and end indexes

>>> sample_slice = sample.slice(start=3, end=5)
>>> sample_slice.to_dataframe()
          cp        llr
0  61.164182  198.98697
1  30.204422  269.86955
