Feature

class braintools.cogtask.Feature(num, name=None)

Individual feature encoder for cognitive task inputs/outputs.

A Feature defines the encoding dimensions for a single input or output channel in a cognitive task.

Examples

>>> # Simple fixation feature
>>> fix = Feature(1, 'fixation')

>>> # Stimulus with higher dimensionality
>>> stim = Feature(8, 'stimulus')

>>> # Compose features
>>> all_features = fix + stim
>>> print(all_features.num)  # 9 (1 + 8)

>>> # Repeat features
>>> repeated = Feature(2, 'choice') * 3
>>> # Creates: choice_0, choice_1, choice_2

Parameters:

• num (int) – Number of dimensions for this feature.

• name (str) – Feature name. Required for composition.
