Filter

brainstate.typing.Filter

Flexible filter type that can be a single filter or combination of filters.

This allows for complex filtering patterns by combining multiple filter criteria.

Examples

>>> # Single filter
>>> simple_filter: Filter = "weight"
>>>
>>> # Tuple of filters (all must match)
>>> combined_filter: Filter = (float, "weight")
>>>
>>> # List of filters (any can match)
>>> alternative_filter: Filter = [int, float, "bias"]
>>>
>>> # Nested combinations
>>> complex_filter: Filter = [
...     ("weight", lambda p, x: x.ndim == 2),  # 2D weight matrices
...     ("bias", lambda p, x: x.ndim == 1),    # 1D bias vectors
... ]
