"""Returns 1 when `x` falls inside the bounds, between 0 and 1 otherwise.
|

|

Args:
|
||||
x: A scalar or numpy array.
|
||||
bounds: A tuple of floats specifying inclusive `(lower, upper)` bounds for
|
||||
the target interval. These can be infinite if the interval is unbounded
|
||||
at one or both ends, or they can be equal to one another if the target
|
||||
value is exact.
|
||||
margin: Float. Parameter that controls how steeply the output decreases as
|
||||
`x` moves out-of-bounds.
|
||||
* If `margin == 0` then the output will be 0 for all values of `x`
|
||||
outside of `bounds`.
|
||||
* If `margin > 0` then the output will decrease sigmoidally with
|
||||
increasing distance from the nearest bound.
|
||||
sigmoid: String, choice of sigmoid type. Valid values are: 'gaussian',
|
||||
'linear', 'hyperbolic', 'long_tail', 'cosine', 'tanh_squared'.
|
||||
value_at_margin: A float between 0 and 1 specifying the output value when
|
||||
the distance from `x` to the nearest bound is equal to `margin`. Ignored
|
||||
if `margin == 0`.
|
||||
|
||||
Returns:
|
||||
A float or numpy array with values between 0.0 and 1.0.

Raises:

ValueError: If `bounds[0] > bounds[1]`.

ValueError: If `margin` is negative.
