nnmnkwii.util.remove_zeros_frames¶

nnmnkwii.util.remove_zeros_frames(x, eps=1e-07)[source]¶

Remove zeros frames.

Given a feature matrix, remove all zeros frames as well as trailing ones.

Parameters:	x (numpy.ndarray) – 2d feature matrix, shape (`T x D`) eps (float) – Values smaller than `eps` considered as zeros.
Returns:	Zeros-removed 2d feature matrix, shape (`T' x D`).
Return type:	numpy.ndarray

Examples

>>> import numpy as np
>>> from nnmnkwii.util import remove_zeros_frames
>>> x = np.random.rand(100,10)
>>> y = remove_zeros_frames(x)
