Logical¶
Logical functions stream generator.
Make a toy dataset with three labels that represent the logical functions: OR
, XOR
, AND
(functions of the 2D input).
Data is generated in 'tiles' which contain the complete set of logical operations results. The tiles are repeated n_tiles
times. Optionally, the generated data can be shuffled.
Parameters¶
-
n_tiles
Type → int
Default →
1
Number of tiles to generate.
-
shuffle
Type → bool
Default →
True
If set, generated data will be shuffled.
-
seed
Type → int | None
Default →
None
Random seed for reproducibility.
Attributes¶
-
desc
Return the description from the docstring.
Examples¶
from river.datasets import synth
dataset = synth.Logical(n_tiles=2, shuffle=True, seed=42)
for x, y in dataset.take(5):
print(x, y)
{'A': 1, 'B': 1} {'OR': 1, 'XOR': 0, 'AND': 1}
{'A': 0, 'B': 0} {'OR': 0, 'XOR': 0, 'AND': 0}
{'A': 1, 'B': 0} {'OR': 1, 'XOR': 1, 'AND': 0}
{'A': 1, 'B': 1} {'OR': 1, 'XOR': 0, 'AND': 1}
{'A': 1, 'B': 0} {'OR': 1, 'XOR': 1, 'AND': 0}
Methods¶
take
Iterate over the k samples.
Parameters
- k — 'int'
