NaiveNormalize

class torch_ecg._preprocessors.NaiveNormalize(mean: Union[numbers.Real, numpy.ndarray] = 0.0, std: Union[numbers.Real, numpy.ndarray] = 1.0, per_channel: bool = False, **kwargs: Any)

Bases: torch_ecg._preprocessors.normalize.Normalize

Naive normalization.

Naive normalization defined as

\[\frac{sig - m}{s}\]

Parameters

• mean (numbers.Real or numpy.ndarray, default 0.0) – Value(s) to be subtracted.

• std (numbers.Real or numpy.ndarray, default 1.0) – Value(s) to be divided.

• per_channel (bool, default False) – If True, normalization will be done per channel.

Examples

from torch_ecg.cfg import DEFAULTS
sig = DEFAULTS.RNG.randn(1000)
pp = NaiveNormalize()
sig, _ = pp(sig, 500)
