constant_suffix_remover

Provides a Sparsifier which removes constant suffixes.

class ConstantSuffixRemover(n: int = 10, epsilon: float = 0.001, mode: str = 'relative')

Bases: Sparsifier

A sparsifier which removes constant suffixes.

frac

The relative amount of samples to keep from the incoming signal.

0 <= frac <= 1.

Raises:

• TypeError – If frac is not a float.

• ValueError – If frac not in the interval [0, 1].

Inits the ConstantSuffixRemover.

Parameters:

• n – The minimum length of the suffix to remove.

• epsilon – Relative size of the epsilon-neighbourhood of the suffix.

• mode – Wether the espilon neighborhood is “relative” or “absolute”.

Raises:

• TypeError – If n is not an int.

• ValueError – If n is negative or epsilon is negative.

• TypeError – If epsilon is neither float nor int.

• ValueError – If mode is neither “absolute” nor “relative”.

sparsify(signal: DataFrame) → DataFrame

Sparsifies the signal by constant suffixes.

Parameters:
