Subtract#

class deeptrack.features.Subtract(value: float | Callable[[...], float] = 0, **kwargs: dict[str, Any])#

Bases: ArithmeticOperationFeature

Subtract a value from the input.

This feature performs element-wise subtraction (-) from the input.

Parameters#

value: PropertyLike[int or float], optional

The value to subtract from the input. Defaults to 0.

**kwargs: dict of str to Any

Additional keyword arguments passed to the parent constructor.

Examples#

>>> import deeptrack as dt

Create a pipeline using Subtract: >>> pipeline = dt.Value([1, 2, 3]) >> dt.Subtract(value=2) >>> pipeline.resolve() [-1, 0, 1]

Alternatively, the pipeline can be created using operator overloading: >>> pipeline = dt.Value([1, 2, 3]) - 2

Or: >>> pipeline = -2 + dt.Value([1, 2, 3])

Or, more explicitly: >>> input_value = dt.Value([1, 2, 3]) >>> sub_feature = dt.Subtract(value=2) >>> pipeline = sub_feature(input_value)
